In this embodiment, as shown in FIG. 1, a waste liquid treatment control device 100 of the present invention is connected to office devices 200-1 to 200-m (m is a natural number).
Each of the office devices 200-1 to 200-m is a device that manages each of a plurality of offices that perform water treatment, and possesses waste liquid data regarding water treatment in the office. The waste liquid data includes the type of substance contained in the waste liquid generated in the business establishment, the properties including the concentration and pH value of the substance, the temperature of the waste liquid, and the amount of the waste liquid. Waste liquid data may be measured values such as properties, but it may also be information that enables calculation of estimated values of waste liquid properties (e.g., amount of water used in the business site, type of chemicals used, amount of chemicals used). good. In addition, the waste liquid data may further include information indicating the processing cost, time, calorific value, etc. required when the waste liquid used in the business site is treated to a level that can be discharged by the business site alone. Since each of the office devices 200-1 to 200-m owns such waste liquid data, it goes without saying that it has a function of measuring each parameter of the waste liquid generated in internal processing. Further, each of the office devices 200-1 to 200-m has a communication function and is connected to the waste liquid treatment control device 100 so as to be communicable. The form of connection between each of the office devices 200-1 to 200-m and the waste liquid treatment control device 100 may be a connection via the Internet, which is a communication network, or a direct connection. It can be. Note that each of the office devices 200-1 to 200-m may be installed inside the office to be managed, or may be installed outside the office. Also, one office device may manage a plurality of offices.

FIG. 2 is a diagram showing an example of the internal configuration of the waste liquid treatment control device 100 shown in FIG. The waste liquid treatment control device 100 shown in FIG. 1 has an acquisition unit 110, a database 120, a calculation unit 130, and an output unit 140, as shown in FIG. 2 shows main elements in this embodiment among the constituent elements of the waste liquid treatment control apparatus 100 shown in FIG.

The acquiring unit 110 acquires the waste liquid data in each of the offices managed by each of the office devices 200-1 to 200-m. In addition, the acquiring unit 110 acquires transfer burden data indicating the burden of transferring the waste liquid between offices managed by the office devices 200-1 to 200-m. This movement burden data is calculated based on the positions of the offices managed by the office devices 200-1 to 200-m owned by the office devices 200-1 to 200-m. It is data that shows the burden calculated based on the distance and height difference, means of transportation between business sites (vehicle with mixing function, ship with mixing function, connecting pipe with mixing function, etc.), amount of waste liquid to be transported, etc. It may be calculated and held by the office devices 200-1 to 200-m, or may be calculated and held by the waste liquid treatment control device 100. FIG.
The database 120 stores substances that have the potential to meet or approach preset standard values in the properties of the mixed waste liquid by mixing at least two types of waste liquids and reacting substances contained in the waste liquids. Combination data indicating the combination of are stored in advance. The combination data may be, for example, data indicating a combination of an acidic substance and an alkaline substance, or data indicating a combination of an oxidizing substance and a reducing substance. Furthermore, the combination data may include, in addition to the combination of substances, information on chemical reactions between the substances of the combination. For example, the combination data may include information about heat of reaction when the substances of the combination cause a chemical reaction. Also, the database 120 stores such reference values in advance. This standard value may be a standard value based on laws or a voluntary standard. In addition, this reference value may be a value indicating the level at which the waste liquid can be discharged to the outside, or a value at which the waste liquid can be discharged to the outside by mixing the waste liquid with a small amount of other chemicals. good.

As shown in FIG. 3, the database 120 shown in FIG. 2 stores two waste liquids (waste liquid 1 and waste liquid 2) in association with mixing ratios. For example, as shown in FIG. 3, the substance "a" contained in the waste liquid 1, the substance "b" contained in the waste liquid 2, and the mixing ratio "1:1" are associated with each other. This is because if the substance “a” and the substance “b” are mixed at a ratio of “1:1”, the concentration of “a” in the waste liquid 1 will be and the concentration of "b" in waste liquid 2 meets or approaches a preset reference value. Further, the substance "c" contained in the waste liquid 1, the substance "d" contained in the waste liquid 2, and the mixing ratio "1:2" are associated with each other. This is because if the substance “c” and the substance “d” are mixed at a ratio of “1:2”, the reaction between the substance “c” and the substance “d” will cause the concentration of “c” in the waste liquid 1 to and the concentration of "d" in waste liquid 2 satisfies the preset reference value or approaches the reference value.

In addition, the calculation unit 130 calculates the processing burden (second processing burden) in the case of disposing of the waste liquid that does not meet the standard values at each of the business establishments managed by the business establishment devices 200-1 to 200-m. do. These first processing burden and second processing burden are calculated based on the combination data stored in the database 120 and the waste liquid data and movement burden data acquired by the acquisition unit 110 . Further, the calculation unit 130 calculates at least one of the cost, time, and calorific value required for water treatment as the first processing burden and the second processing burden. Further, the calculation unit 130 calculates the amount of waste generated when the waste liquids in each of the offices managed by the office devices 200-1 to 200-m are mixed with each other, including the amount of the waste in the first processing burden. can be

First, the acquiring unit 110 acquires waste liquid data from the office devices 200-1 to 200-m (step S1). Next, based on the waste liquid data acquired by the acquisition section 110, the calculation section 130 determines whether or not the waste liquid of the office devices 200-1 to 200-m needs to be treated (step S2). Specifically, the calculation unit 130 determines whether or not the waste liquid data acquired by the acquisition unit 110 satisfies the reference value stored in the database 120. If the reference value is not satisfied, the office device 200- It is determined that some sort of treatment is necessary for the 1 to 200-m waste liquid.
When the calculation unit 130 determines that the waste liquids of the office devices 200-1 to 200-m do not need to be treated, the output unit 140 outputs information indicating an instruction to discharge the waste liquids (step S3).

On the other hand, when the calculation unit 130 determines that some kind of treatment is necessary for the waste liquid of the business office devices 200-1 to 200-m, the calculation unit 130 determines that the office devices 200-1 to 200-m manage It is determined whether the combinations stored in the database 120 can be achieved by combining the waste liquids in each (step S4). Specifically, for example, when the database 120 stores the correspondence shown in FIG. If information indicating the substance b in the waste liquid is included in the waste liquid data acquired from the office device 200-2, the combination of the substance a and the substance b is stored in the database 120, so the calculation unit 130 determines that the combination stored in the database 120 can be achieved with the waste liquid from the business establishment managed by the business establishment device 200-1 and the waste liquid from the business establishment managed by the business establishment device 200-2. .

If it is determined that the combination stored in the database 120 can be realized by combining the waste liquids in the respective business sites managed by the business site devices 200-1 to 200-m, the determined combination , the acquisition unit 110 acquires movement burden data for moving waste liquid between offices to be combined (step S5). Then, the calculation unit 130 calculates a burden (first processing burden) when the waste liquid is mixed between the offices to be combined (step S6). In addition to the burden (time and cost) of transferring waste liquids between business sites calculated based on the transfer burden data, the burden of mixing waste liquids includes, for example, the type of waste generated when mixing waste liquids. These include the amount of heat, the amount of heat generated, the time and cost required for mixing, and the like. The same applies to other "burdens" described below. Further, these are calculated based on the waste liquid data acquired from the office equipment of the office to be combined and the data stored in advance in the database 120 when performing the mixing process. Further, the calculation unit 130 calculates the burden (second processing burden) when the business establishments to be combined process the waste liquid for each business establishment (step S7). The calculation unit 130 calculates the burden of processing the waste liquid for each business establishment based on the waste liquid data acquired from the business establishment.

After the calculation unit 130 calculates the first processing load and the second processing load, the output unit 140 outputs the result calculated by the calculation unit 130 (step S8).

On the other hand, in step S4, it is determined that the combinations stored in the database 120 cannot be realized even if the waste liquids in the respective offices managed by the office devices 200-1 to 200-m are combined with each other. In this case, the calculation unit 130 calculates the burden (second processing burden) when the establishment alone treats the waste liquid (step S9). Then, in step S8, the output unit 140 outputs the result calculated by the calculation unit 130. FIG.

Note that the output unit 140 displays both the first processing load and the second processing load as the result calculated by the calculation unit 130, so that the user viewing the display can select the processing method. of comparative elements can be presented. In addition, the output unit 140 compares the cost of the first processing load and the cost of the second processing load, and displays a screen prompting the user to perform the process with the lower cost. By doing so, it is possible to support appropriate selection when a processing method that gives priority to cost is to be selected. Not only the cost but also the time required for processing (mixing), calorific value, and the total amount of waste liquid generated including the amount of chemicals used are compared for the priority factors, and as a result, the burden is small. The output unit 140 displays a screen prompting the user to perform the first process.

On the other hand, when the calculation unit 130 determines that some processing is necessary for the waste liquids of the office devices 200-1 to 200-m, the calculation unit 130 determines that the pH value of the waste liquid n (n is a natural number) is in the middle of the waste liquid A. It is determined whether or not summation is possible (step S14). If neutralization is possible, the calculator 130 calculates the pH value after mixing the waste liquid A and the waste liquid n based on the properties of the waste liquid A and the waste liquid n (step S15).

Also, when the calculation unit 130 calculates the temperature after mixing the waste liquid A and the waste liquid n, the calculation unit 130 determines whether the calculated temperature is a legally dischargeable value. Specifically, the calculation unit 130 compares the calculated temperature with the regulation database stored in the database 120, and determines whether the calculated temperature satisfies the conditions of the regulation database. Note that the processing of steps S14 to S16 may determine whether or not there is a correspondence between the waste liquid A and the waste liquid n in the correspondence stored in the database 120 as shown in FIG.

Further, the calculation unit 130 calculates the load when the waste liquid A and the waste liquid n are mixed based on the waste liquid data acquired from each office device 200-1 to 200-m and the movement load data as described above. do. Then, the calculation unit 130 calculates the effect of reducing the burden in the case where the office apparatus 200-1 mixes the waste liquid compared to the case where the office apparatus 200-1 treats the waste liquid independently (step S17). This effect is superior in terms of cost effect, time effect, reduction of calorific value, reduction of amount of waste generated, etc. is the point. Then, the calculation unit 130 determines whether or not the calculated burden reduction effect satisfies the customer's condition (step S18).
