The present invention relates to a fermentation treatment apparatus and a fermentation state determination method for efficiently performing fermentation treatment of organic waste by predicting a predicted input timing and a predicted input amount at the time of performing.

Waste treatment apparatuses that ferment organic waste with microorganisms are widely known. For example, Document 1 discloses a technique that includes a state quantity detection unit and a control unit such as moisture, humidity, temperature, and carbon dioxide concentration, and controls the fermenter according to a signal from the state quantity detection unit. . Moreover, in the literature 2, in the fermentation treatment of organic waste, the weight or weight change and temperature or temperature change of the fungus bed containing the organic waste are measured and accumulated, and the present fermentation state is determined by these analyzes.

Further, Document 2 discloses an organic waste fermentation treatment apparatus and a treatment method for predicting a fermentation state after determination, selecting an operation mode corresponding to the prediction, and controlling the apparatus.
JP-A-8-309317, paragraph 0044 and the like. JP2003-145105, paragraph 0014, FIGS.

  In the disclosed technology of Document 1, the state of moisture is detected directly or indirectly by detecting the state quantity, and the apparatus is controlled according to the state quantity, so that the microbial carrier is used for the growth of degrading bacteria. It is said that it can be maintained in a suitable environment. However, the determination index of the state of the fermenter of the fermentation treatment apparatus with respect to the signal from the state quantity detection means is controlled according to the state quantity, and no clear definition is disclosed or suggested.

  In the disclosed technology of Document 2, the current fermentation state is judged by analyzing the weight change and temperature change of the fungus bed containing organic waste, the future fermentation state is predicted, and the corresponding operation mode is selected. There are clear criteria for controlling the equipment, but the concentration of carbon dioxide is not measured. Therefore, it is difficult to accurately determine the current fermentation state and accurately predict the future fermentation state.

  In view of the above-described problems, in the present invention, in the fermentation treatment of organic waste, measurement data of the carbon dioxide concentration in the fermenter, the weight and temperature of the organic waste is measured and acquired, and the measurement data and the predetermined data are obtained. Stored data composed of processing data such as temperature, weight change and temperature change for the time is obtained. Determine the fermentation state of organic waste after a predetermined time from the stored data, and output the prediction result to predict the predicted input time and predicted input amount for the next fermentation treatment of organic waste. To do.

The present invention for solving the above problems is configured as follows. That is, the first configuration obtains each measurement data including the carbon dioxide concentration in the fermenter (12) for fermenting the organic waste (W), the temperature of the organic waste (W), and the weight. Part (1), and a processing part (2) for obtaining each processing data comprising a temperature change amount, a weight change amount, an input amount, and a temperature change tendency of the organic waste (W) based on each measurement data Based on the measurement data and the processing data, the carbon dioxide concentration (A), the temperature change amount (B) of the organic waste (W), the weight change amount (C), the input amount (D), the temperature (E), and the combination of temperature change tendency (F), storage unit for storing each data stored chronologically consisting (3) and, the classified classification conditions depending on the value of the storage data (P) a classification table defining the (5), the combination of the classification condition (P) A decision table defining the determination result to respond (6), wherein the value of each stored data against the classification conditions (P) of the condition table, and extracts the matching classification number (Pn) from the combination of the classification conditions And a determination unit (4) for outputting a determination result corresponding to the classification number (Pn) from the determination table.

The determination result is a determination result (Q) composed of the fermentation state (Qa) and the fermentation progress (Qb) of the organic waste (W) after a predetermined time has elapsed. As the expression of the fermentation state, there are fermentation states such as “normal” that is normal fermentation, “bad” that fermentation is poor, and “abnormal” that indicates some abnormality. As the expression of the degree of progress of fermentation, there are fermentation states such as “initial stage” at the start of fermentation, “ongoing” during active fermentation, and “late” at the end of fermentation. Moreover, the expression of a fermentation state can be expressed by these combinations .

Another judgment result is a prediction result (R) composed of a predicted input amount (Ra) and a predicted input time (Rb) when performing the next fermentation treatment of organic waste (W). To do. Estimated input amount is `` regulated amount '' when the fermentation is normal and the remaining amount of organic waste is small, etc. `` Half '' or `` When the fermentation is delayed and the remaining amount of organic waste is large '' “1/5”, in case of abnormal fermentation such as excessive moisture, “discontinuation of input” is selected and output. As the predicted input time, the estimated input amount (Ra) for the next fermentation treatment of the organic waste (W) is output after what time from the input, and the state explanation matter in the fermenter when the predetermined time has elapsed Output if there is. In addition, based on the output of the prediction result, it is also possible to adopt a fermentation treatment apparatus configured to input the predicted amount of organic waste into the fermenter at the predicted input time from a hopper that is a storage unit for organic waste. Is possible. The determination result has a notifying unit (7) for notifying. The notification unit, audible notification that can inform the determination result such as site worker, there is a character broadcast to visual notification, or on a monitor such as by lighting the lights. It is also possible to transmit the notification contents to a remote manager to perform auditory, visual, or text notification.

Next, the organic waste fermentation treatment apparatus of the present application is characterized in that it takes the following fermentation state determination method.
That is, based on each measurement data consisting of the carbon dioxide concentration in the fermenter (12) for fermenting the organic waste (W), the temperature of the organic waste (W), and the weight, the organic waste ( W), each processing data including a temperature change amount, a weight change amount, an input amount, and a temperature change tendency is formed, and based on each measurement data and each processing data, the carbon dioxide concentration (A), the organic property Temperature change amount (B), weight change amount (C), input amount (D), temperature (E), and temperature change tendency (F) of waste (W) are stored in time series to form each stored data. And
Based on the stored data, the classification number is specified from the classification table (5) that defines the combination specifications of the classification conditions (P) classified in advance in consideration of the values of the respective storage data (A to F). Based on the classification number, the determination result from the determination table (6a) defining the combination of the fermentation state (Qa) and the fermentation progress (Qb) of the organic waste (W) after the predetermined time has passed, and the next time Judgment is made by extracting a prediction result (R) from a prediction table (6b) that defines a combination of a predicted input amount (Ra) and a predicted input time (Rb) when performing fermentation treatment of organic waste (W). It is characterized by being output as a result .

One of the determination results is a determination result (Q) composed of the fermentation state (Qa) and the fermentation progress (Qb) of the organic waste (W) after a predetermined time has elapsed. The other determination result is a prediction result (R) including a predicted input amount (Ra) and a predicted input time (Rb) when performing the next fermentation treatment of the organic waste (W) .

In the present invention, the fermented state of the organic waste in the fermenter is compared with the classification conditions of the classification table defined in accordance with the value of each stored data, and a suitable classification number is extracted from the combination of classification conditions, It is set to output the determination result of the fermentation state of the organic waste corresponding to the classification number. Specific judgment results include judgment results for judging the fermentation state and fermentation progress of organic waste, and predictions for predicting the predicted input time and predicted input amount for the next fermentation treatment of organic waste Consists of results. Based on the prediction result, the predicted input timing and the predicted input amount are instructed, and the organic waste is input to the fermentation treatment apparatus automatically or manually. In the present invention, steady operation such as maintaining constant agitation and ensuring a constant exhaust amount may be performed, and therefore operation control other than these is unnecessary. Even in the case of a conventional fermentation treatment device, control such as heating of organic waste by heating or increase in the number of agitation is not very effective in the state of abnormal fermentation. It is based on what cannot be done.

The meaning of the classification condition in the classification table will be described in detail below.
1. Regarding carbon dioxide concentration For carbon dioxide concentration, an upper limit value after a predetermined time and several other values were set as the first classification condition. Organic waste put into the fermenter of fermentation treatment equipment is decomposed into water and carbon dioxide by appropriately fermenting, but the concentration of carbon dioxide increases with fermentation, and organic waste The maximum concentration is reached several hours before the temperature of the waste reaches its maximum temperature, after which the carbon dioxide concentration decreases. By measuring the carbon dioxide concentration in the fermenter, it is possible to directly determine the fermentation state accurately and quickly. Experiments have confirmed that the concentration of carbon dioxide emitted with the decomposition of organic waste increases prior to the increase in temperature of the organic waste. This requires a considerable amount of heat to raise the temperature of the organic waste, so even if the decomposition of the organic waste by fermentation becomes active, the temperature of the organic waste will not rise for a while. Because.

2. About the amount of temperature change It has been conventionally known that the decomposition rate decreases when the maximum fermentation temperature exceeds 60 ° C, the appropriate fermentation temperature is set to 50 ° C, and the culture temperature of 30 ° C used for general bacterial testing is set. When the minimum compensation temperature of the fermenter of the fermentation treatment apparatus was used, the difference of 20 ° C was set as the second classification condition. In the fermenter of the fermenter, aerobic bacteria are propagated by appropriately sending fresh air from the outside, and heat is generated due to the decomposition of organic matter when it is propagated. You can know the fermentation state. The time required to reach the maximum temperature varies depending on the amount and type of organic waste to be treated. It is necessary to set appropriately the predetermined time required for the fermentation treatment of organic waste.

3. About the amount of weight change The third target is to reduce the weight of the organic waste in the organic waste by 50% from the input of the organic waste to the time when the organic waste reaches the maximum temperature. Condition. When an appropriate amount of organic waste is introduced with respect to the fermenter capacity of the fermentation treatment apparatus, the weight decreases by about 50% as the temperature rises. This is mainly due to the decomposition of organic matter into water and carbon dioxide. As the temperature of the organic waste in the fermenter rises due to fermentation, moisture is evaporated as water vapor, so that ventilation to the organic waste is also ensured.

4). About the amount of input In order to continue fermentation of organic waste, it is necessary to experiment that it is necessary to input more than 20% of the specified amount of organic waste when the water content of organic waste is 80%. Since it was found, the case where the input amount of organic waste at the time of input was less than 1/5 of the specified amount was set as the fourth classification condition. Microorganisms in the fermenter decrease if nutrients are insufficient, but the amount of organic waste discharged at each office is often not constant, so the nutritional state is also not constant. In addition, even during normal fermentation, if the amount of organic waste input is small, moisture and nutrients may be insufficient, the fermentation state may deteriorate at a stretch, and drying must be avoided. is doing.

5). Regarding temperature The temperature of the organic waste at the time of the introduction of the organic waste was defined and it was classified as the fifth classification condition. Despite normal fermentation and the temperature of organic waste is rising, if organic waste with low temperature is introduced, even if the temperature of the fermentation tank of the fermentation treatment apparatus is sufficient, This is because the temperature of the organic waste is lowered, and subsequent fermentation cannot be continued normally.

6). Regarding temperature change tendency When the temperature is decreasing and the fermentation is judged to be normal based on the consideration up to the fifth classification condition, it is determined that the organic waste can be input with the sixth classification condition. To do. The temperature change tendency is determined by dividing the predetermined time into equal parts and acquiring and storing temperature data for each lapse of time. The current organic waste temperature is higher than the previous data. If the current temperature of the organic waste is low, it is determined that the temperature is decreasing. If it is determined that the temperature has risen in the majority of the segment time within the predetermined time, it is determined that the temperature is rising. The same applies to the determination of whether the temperature is decreasing. However, it can also be determined that it can be put in after 24 hours, except when the fermentation is abnormal. Furthermore, in the case of a fermentation treatment apparatus with a large capacity of the fermenter, that is, a large amount of treatment, the heat retention capability of the organic waste itself is increased, and therefore the temperature rise and fall may not be obvious. However, even in this case, if the fermentation state is good, the carbon dioxide concentration increases, so that it is determined that the state can be charged after 24 hours.

  In addition, the said code | symbol is attached | subjected for understanding of the content of invention, and the technical idea of this invention should not be limitedly interpreted by these code | symbols.

  In the present invention, the fermentation state of the organic waste is judged by the main body of the fermentation treatment apparatus, and the fermentation state of the organic waste is determined based on the determination result and the prediction result, and the predicted amount of organic waste is added at the predicted input time. Since it can be put into the fermenter of the fermentation treatment apparatus, normal fermentation can be continued without having specialized knowledge or experience. Furthermore, since it is not necessary to control a special fermentation treatment apparatus, it is not necessary to manufacture a new fermentation treatment apparatus, and it is possible to connect to a fermentation tank of an existing fermentation treatment apparatus. Therefore, unlike a conventional fermentation treatment apparatus, a fermentation treatment apparatus with reduced cost can be provided. As described above, the industrial effect of the present invention is extremely remarkable.

  Embodiments of the present invention will be described in detail below. FIG. 8 is an explanatory diagram of the fermentation treatment apparatus in the present embodiment. The fermentation processing apparatus S uses a conventional technique, and a fermenter 12 is formed therein. An inlet 9 for organic waste W is disposed on the upper side of the fermentation treatment apparatus S, and an exhaust pipe 10 and an intake pipe 11 for ventilating the fermentation tank 12 and the outside are disposed. The exhaust pipe 10 forcibly exhausts a certain amount of air per unit time from the inside of the fermenter 12 to the outside, and a quantitative exhaust pump or the like can be used. The intake pipe 11 sucks the same amount of air exhausted by the exhaust pipe 10 to the outside from the outside to the inside of the fermentation tank 12 and has a check valve for preventing a reverse flow from the inside of the fermentation tank 12 to the outside. Piping etc. can be used. A stirring unit 13 is arranged inside the fermenter 12. The stirring unit 13 is for stirring the organic waste W, and a motor-driven stirring blade or the like can be used. A storage unit 14 for storing the organic waste W from the next time is disposed above the input port 9. A hopper or the like can be used as the storage unit 14. The fermentation treatment apparatus S performs only steady operation such as maintaining constant stirring and securing a certain displacement, and does not perform any other operation control.

FIG. 1 is an operation block diagram of the fermentation treatment apparatus in the present embodiment. In the present embodiment, the fermentation treatment of the organic waste W by the fermentation treatment apparatus S will be described for a case where the specified amount to be charged once is 15 kg. The fermentation processing apparatus S for organic waste W according to this embodiment includes an acquisition unit 1, a processing unit 2, a storage unit 3, a determination unit 4, and a notification unit 7.
The acquisition unit 1 acquires each measurement data from the carbon dioxide concentration measurement unit 1a, the temperature measurement unit 1b, and the weight measurement unit 1c arranged in the fermentation treatment apparatus S. The carbon dioxide concentration measuring unit 1a is a carbon dioxide concentration measuring means such as an infrared gas analyzer, and is connected to the exhaust pipe 10 to measure the carbon dioxide concentration in the fermenter 12. The temperature measuring unit 1 b is a temperature measuring means such as a thermocouple or a resistance thermometer attached to the inner wall of the fermenter 12, and measures the temperature of the organic waste W put into the fermenter 12. The weight measuring unit 1c is a weight measuring unit such as a load cell arranged on the lower side of the fermentation processing apparatus S, and measures the weight of the organic waste W put into the fermentation processing apparatus S. Each measurement data of carbon dioxide concentration, temperature and weight acquired by the acquisition unit 1 is sent to the next processing unit 2.

  The processing unit 2 acquires processing data including a temperature change amount, a weight change amount, an input amount, and a temperature change tendency of the organic waste W from each measurement data for a predetermined time acquired by the acquisition unit 1. The measurement data of the carbon dioxide concentration is sent to the storage unit 3 without being processed by the processing unit 2. In this embodiment, 8 hours required for the fermentation treatment time of the organic waste W are adopted as the predetermined time. It should be noted that it is possible to set a predetermined time that is appropriately increased or decreased depending on factors such as the state and type of the organic waste W, the temperature of the organic waste W at the time of input, and the outside air temperature.

Based on the measurement data and the processing data, the storage unit 3 stores the carbon dioxide concentration A, the temperature change amount B, the weight change amount C, the input amount D, the temperature E, and the temperature change tendency F of the organic waste W. Each stored data for a predetermined time is stored in time series.
The carbon dioxide concentration A is the carbon dioxide concentration in the fermenter 12 after a predetermined time has elapsed. The temperature change amount B is a value obtained by subtracting the temperature of the organic waste W at the time of charging from the temperature of the organic waste W after a predetermined time has elapsed. The weight change amount C is a value obtained by subtracting the weight of the organic waste W at the time of charging from the weight of the organic waste W after a predetermined time has elapsed. The input amount D is the weight of the organic waste W at the time of input, and does not include the weight of the worm carrier or sawdust. The temperature E is the temperature of the organic waste W after a predetermined time has elapsed. The temperature change tendency F indicates whether the slope of the temperature change of the organic waste W after the elapse of a predetermined time is either rising or falling. As for the temperature change tendency F, measurement data is processed as follows because there may be an upward and downward wave. Eight hours, which is the predetermined time, are equally divided into, for example, a plurality of every 30 minutes, and the measured data at the time of measurement is compared with the measured data of 30 minutes before, and the slope of the temperature change for each divided time either increases or decreases Calculate whether or not. The one where the number of times of rising or falling is larger may be adopted as the temperature change tendency.

  The determination unit 4 collates each stored data A to F with a predetermined classification condition P and outputs a determination result of the fermentation state of the organic waste W. In FIG. 2, the classification conditions Pa to Pf of the same type as the stored data A to F are defined in order to collate with the values of the stored data A to F. Hereinafter, the details of each of the classification conditions Pa to Pf will be described. For the carbon dioxide concentration A, the carbon dioxide concentration Pa is “5% or more”, “less than 5% to 2.5% or more”, “less than 2.5% to 0.5% or more”, and “less than 0.5%”. Are classified into four categories. Similarly, regarding the temperature change amount B of the organic waste W, the temperature change amount Pb is classified into “+ 20 ° C. or higher” and “less than + 20 ° C.”. Regarding the weight change amount C, the weight change amount Pc is classified into two types, “−50% or more” and “less than −50%”. For the input amount D, the predicted input amount Pd is classified into two categories: “specified amount” and “less than 1/5”. Regarding the temperature E, the temperature Pe is classified into “40 ° C. or more and less than 45 ° C.” and “less than 40 ° C.”. Regarding the temperature change tendency F, the temperature change tendency Pf is classified into two categories, “up” and “down”.

FIG. 3 defines combinations of the classification conditions Pa to Pf in FIG. Although not all combinations of the classification conditions Pa to Pf are defined in FIG. 3, this is due to the following reason. For example, when the carbon dioxide concentration Pa is “5% or more” or “less than 0.5%”, it is considered that exhaustion is defective or intake is excessive, or the activity of microorganisms is inactive. This is because the fermentation state is not subject to judgment. For each of the other classification conditions Pb to Pf, if it is considered that the classification can be performed only by a combination of the other classification conditions, values and ranges are arbitrary (right arrow in FIG. 3).

The determination unit 4 that collates the stored data A to F and the classification conditions Pa to Pf is subdivided into a determination unit 4a and a prediction unit 4b.
The determination unit 4a collates each stored data A to F in the storage unit 3 with each classification condition Pa to Pf in the classification table 5, and specifies a classification number Pn corresponding to the combination of the matching classification conditions Pa to Pf. And a determination result Q is output as a determination result from the determination table 6a (to be described later) corresponding to the same number as this number.
Further, the prediction unit 4b collates the storage data A to F of the storage unit 3 with the classification conditions Pa to Pf of the classification table 5, and determines the classification number Pn corresponding to the matching combination of the classification conditions Pa to Pf. This is a part that is specified and extracted, and outputs a prediction result R as a determination result from the prediction table 6b (to be described later) corresponding to the same number as this number.
As shown in FIG. 4, the determination table 6a defines a determination number Qn corresponding to each combination of the fermentation state Qa and the fermentation progress Qb. According to the extracted classification number Pn, the fermentation state Qa and the fermentation progress Qb corresponding to the same determination number Qn are extracted from the determination table 6a and output to the notification unit 7 as the determination result Q.
Further, as shown in FIG. 5, the prediction table 6b defines a prediction number Rn corresponding to various combinations of the predicted input amount Ra and the predicted input time Rb. In accordance with the classification number Pn, the predicted input amount Ra, the predicted input time Rb and the prediction table 6b corresponding to the prediction number Rn having the same number are extracted from the prediction table 6b and output as the prediction result R to the notification unit 7 and the input unit 8. is there.
In the present invention, what is constituted by the above-described determination table 6a and prediction table 6b is referred to as a determination table 6.

The alerting | reporting part 7 alert | reports the determination result Q and the prediction result R which the determination part 4 output to the display monitor (illustration omitted) attached to the fermentation processing apparatus S by a character display . Further, in this embodiment, and outputs as a control signal the prediction result R to the insertion portion 8 from the prediction unit 4b of the determination unit 4.
The input unit 8 uses the control signal from the prediction unit 4b based on the prediction result R , and when the predicted input time Rb is reached, the storage unit 14 connected to the input port 9 of the fermentation treatment apparatus S supplies the organic waste with the predicted input amount Ra. This is a part for giving an instruction to automatically put W or water into the fermenter 12 . When the organic waste W is thrown into the fermentation treatment apparatus S, the time measurement is reset and the measurement of the next charging time starts.

FIG. 6 is a transition diagram for 60 days of carbon dioxide concentration, weight, and temperature in the fermentation treatment process using the fermentation treatment apparatus of this embodiment, and FIG. 7 is a transition diagram for 48 hours. It can be seen that the carbon dioxide concentration in the fermentation treatment apparatus S and the temperature of the organic waste W show a similar transition with a positive correlation. Further, as can be seen from FIG. 7, it is confirmed that the concentration of carbon dioxide increases prior to the rise in temperature, and by measuring the concentration of carbon dioxide in the exhaust gas, a more accurate and quick determination of the fermentation state can be made. . Furthermore, it can be seen from FIG. 7 that before the temperature rises, the concentration of carbon dioxide increases and the activity of microorganisms becomes active. 6 and 7, the initial weight is not zero because the weight including the weight of the organic carrier W and the weight of sawdust and sawdust, which are microbial carriers, is measured. By subtracting the weight before the organic waste W is charged, the input amount D of the organic waste W can be acquired.
[Operation of this embodiment]

  After the input port 9 of the fermentation treatment apparatus S is opened and the organic waste W is input, when the input port 9 is closed, a change in weight is detected, the time measurement is reset, and time measurement starts. The fermentation treatment apparatus S stirs the organic waste W by the stirrer 13, and a fixed amount of air is exhausted from the exhaust pipe 10 per unit time. The weight measuring unit 1c calculates the input amount D by comparing the weight immediately before the input from the weight measured at the time of the input. When the organic waste is introduced into the fermenter 12, the measurement of the carbon dioxide concentration in the exhaust pipe 10 is performed every 10 minutes and the measurement data is stored. And the largest numerical value and the numerical value at the time of insertion are compared with the numerical value preserve | saved after 8 hours pass from the time of injection | throwing, and the difference is acquired. The temperature of the organic waste W is stored every 10 minutes. In the case of 8 hours, the difference between the 48th data and the temperature is taken. The temperature data is compared every 30 minutes to determine whether the temperature is rising or falling.

After 8 hours, the stored data A to F are ready. As an example, carbon dioxide concentration A = 3.0%, temperature change B = + 15 ° C., weight change C = −55%, input D = 15 kg, temperature E = 35 ° C., temperature change tendency F = store of rise A case where data is obtained will be described. The determination unit 4a and the prediction unit 4b constituting the determination unit 4 collate the stored data A to F with the classification table 5 and extract the classification number P14 as a combination of the classification conditions P.
Subsequently, the determination unit 4 extracts a determination result corresponding to the classification number P14 from the determination table 6 including the determination table 6a and the prediction table 6b, and outputs the result to the notification unit 7. That is, the determination unit 4a, which is a constituent element of the determination unit 4, extracts the determination number Q14 from the determination table 6a as the determination result Q corresponding to the classification number P14 and outputs it to the notification unit 7. Further, the prediction unit 4b, which is another component of the determination unit 4, extracts the prediction number R14 from the prediction table 6b as the prediction result R corresponding to the classification number P14 and outputs it to the notification unit 7.

The notification unit 7 displays, as the determination result Q of the determination unit 4a, the fermentation state Qa = “defective (recovery period)” and the fermentation progress Qb = “continuous fermentation failure”, which are the contents of the determination number Q14, on the monitor. In addition, the notification unit 7 has the prediction amount R as the prediction result R of the prediction unit 4b, that is, the predicted input amount Ra = “specified amount”, the instruction notification content Rb = “fermentation is returning to normal from drying. Please input the specified amount at around hour +16). ”Is displayed on the monitor. “At the time of input” means the time when the organic waste W is input, and in this embodiment, it is approximately 8 hours before the display of the prediction result. Furthermore, the prediction unit 4b transmits the content of the prediction number R14 to the input unit 8 as a control signal. The input unit 8 automatically inputs a predetermined amount of organic waste W, which is the predicted input amount Ra, into the fermenter 12 at the predicted input time Rb from the storage unit 14 connected to the input port 9 of the fermentation treatment apparatus S. To do. This resets the time and starts the next fermentation treatment cycle. In addition, in the fermentation treatment apparatus S by this invention, the organic waste W after a fermentation process is positioned as a high-speed primary fermentation thing, and the utilization to a fertilizer or a soil improvement material is the organic after the fermentation process which is hardly decomposable. For further decomposition of the radioactive waste W, it is preferable to use it after the secondary treatment.
[Possibility of other embodiments]

  It is also possible to adopt a configuration in which the input unit 8 in this embodiment is omitted. When the input unit 8 is omitted, based on the notification result of the notification unit 7, the organic waste W having the predicted input amount Ra is input from the input port 9 of the fermentation processing apparatus S manually in the fermenter 12 at the predicted input time Rb. Is put in, the time measurement is reset and the next fermentation treatment cycle is started.
