Rainwater and sewage (hereinafter, simply referred to as sewage) are stored and allowed to flow down to the settling basin 11. First, the sedimentation tank 11 precipitates the suspended matter in the wastewater and sends the treated water that has been cleaned to some extent to the reaction tank (aeration tank) 12. In the reaction tank (aeration tank) 12, air is blown into the treated water, and the aerobic microorganisms in the returned sludge decompose organic matter in the treated water to precipitate activated sludge.

The final settling tank 13 settles sludge. A part of the sludge settled in the final settling tank 13 is discharged as surplus sludge and treated so that it can be reused. The other sludge is transported to the reaction tank 12 and reused for aeration. Chlorine mixing pond 14 is reaction tank 12
Sodium hypochlorite is injected into the treated water that has flowed out of the mixture, and the mixture is mixed and sterilized. The discharge pipe 15 is a chlorine mixing pond 14.
The treated water that has been sterilized in 1 is flowed down and discharged into the sea or river. The inspection terminal 16 is carried by an equipment inspector and temporarily stores inspection data input by the equipment inspector. This inspection data is the data of the inspection result of the facility to be managed (for example, the above-mentioned sewage treatment plant) according to the inspection items.

Next, the equipment inspection system will be described with reference to the drawings. FIG. 2 is a schematic configuration diagram showing the configuration of the sewage treatment facility according to the embodiment of the present invention. In this figure, the communication unit 21 receives the inspection data output from the inspection terminal 16 and stores the received inspection data in the inspection history database 25. The input unit 22 is, for example, an input device such as a keyboard, a mouse, and a touch panel, and outputs inspection data input by an equipment inspector to the inspection history database 25. The communication unit 21 and the input unit 22 correspond to inspection data acquisition means.

The inspection history database 25 stores the inspection data acquired by the inspection data acquisition means as an inspection history. The reference value database 23 stores the reference data for each inspection item as reference value data. As the reference value data stored in the reference value database 23, for example, reference values relating to water quality as shown in FIG. 3 are stored as reference value data.

The coping information database 24 stores in advance, as coping information, a coping method corresponding to the operation status of the equipment, with respect to the comparison result of the inspection data and the reference value data. This coping information is information on a coping method for reducing the operating cost of the equipment within a range in which the inspection data does not exceed the reference value data. For example, this handling information database 24
The coping information stored in is, for example, as a coping method according to the comparison result between the inspection data of the coliform count and the reference value data of the coliform count as shown in FIG. Data of instructions for increasing or decreasing the injection amount is stored.

The comparison unit 26 reads out the reference value data corresponding to the inspection item of the inspection data from the reference value database 25 and compares the read reference value data with the inspection data acquired by the inspection data acquisition means. The handling information retrieval unit 27 reads the handling information according to the comparison result of the comparing unit 26 from the handling information database 24. The control unit 28 performs control to output the search result searched by the handling information search unit 27 to the output unit 30. In addition, the control unit 28, based on the history of the inspection data stored in the inspection history database 25,
An alarm unit 2 including a speaker and an alarm lamp, if necessary.

It is an output device such as a (Cathode Ray Tube) or a liquid crystal display device, and outputs various information. Bus 31
Performs data transfer between each unit of the device.

Here, the above-mentioned inspection of equipment includes daily inspection and periodic inspection. In the daily inspection, the inspection items are set based on the events necessary to manage whether the equipment is operating or processing normally.For example, the daily inspection items that are regularly determined and the operation data are set. There is an inspection instruction item in which an item to be inspected, which is determined by the control unit 28, is set to be checked more. On the other hand, the periodic inspection includes a maintenance plan item defined in the maintenance plan based on the service life of the equipment and an operation cycle, and an inspection instruction item determined by the control unit 28 based on the operation data and the daily inspection data. According to these inspection items, an equipment inspector inspects equipment disassembly, wear of parts and the like, and quality of operation. Among these inspection items, the inspection items necessary for inspecting the sewage treatment plant are stored in advance in the inspection terminal 16, and the equipment inspector can inspect each part of the equipment according to the inspection items. It is like this.

Next, the operation of the equipment inspection system in this embodiment will be described with reference to the drawings. here,
Of the plurality of inspection items set in the inspection terminal 16, analysis of the number of coliform bacteria, measurement of residual chlorine, and treated state of treated water, which are set as daily inspection items, will be described. Figure 5
6 is a flowchart for explaining the operation of the equipment inspection system.

Treated water such as rainwater and sewage is supplied to the sewer pipe 10.
After being stored in the first settling tank 11, the suspended matter in the wastewater is removed in the first settling tank 11, and the reaction tank 1
2 is sent. Next, in the reaction tank 12, aeration is performed, sludge contained in the treated water is precipitated in the final settling tank 13, sent to the chlorine mixing tank 14, sodium hypochlorite is injected, and sterilization is performed.

The facility inspector carries the inspection terminal 16 with
While patrolling the sewage treatment plant, inspections will be performed sequentially based on the inspection items output on the screen of the terminal. That is, a sample of treated water is collected in the chlorine mixing pond 14 and the number of coliform bacteria is analyzed (step S1), and the number of coliform bacteria as an analysis result is input to the inspection terminal 16 as inspection data (step S2). In addition, the facility inspector measures residual chlorine from the collected treated water sample (step S3),
The measurement result is input to the inspection terminal 16 as inspection data (step S4). Furthermore, the treatment state of the treated water is inspected, and the inspection result is input to the inspection terminal 16 as inspection data. After the inspection is completed, the equipment inspector connects the inspection terminal 16 to the communication unit 21 of the equipment inspection system,
The inspection data is transferred via the communication unit 21.

In the equipment inspection system, after the inspection data received via the communication unit 21 is stored in the inspection history database 25, the comparison unit 26 reads out the inspection data in the analysis item of the number of coliforms and the reference value database 23. The reference value of the number of coliforms is compared, and the comparison result is output to the coping information retrieval unit 27. Furthermore, the equipment inspection system
The inspection data in the measurement of residual chlorine and the reference value data are compared, the inspection data in the treatment state of the treated water and the reference value data are compared, and each comparison result is output to the handling information retrieval unit 27.

In the comparison result output from the comparison unit 26, the countermeasure information retrieval unit 27 determines that the inspection data of the number of coliforms is extremely smaller than the reference value data and the inspection data of residual chlorine is higher than the reference value data. The handling information when the number of coliform bacteria is extremely small and the residual chlorine is high is read from the handling information database 24, and the read handling information is output to the control unit 28. The control unit 28 uses the handling information search unit 2
The handling information output from 7 is output to the output unit 30. In this case, the output section 30 displays a message such as "Please reduce the injection amount of sodium hypochlorite."

On the other hand, in the comparison result output from the comparison unit 26, the inspection data of the number of coliform bacteria is less than the reference value data but is extremely large, the state of water treatment is good, and the inspection data of residual chlorine. Is lower than the reference value data, the handling information corresponding to this comparison result is read from the handling information database 24, and the read handling information is read by the control unit 2.
Output to 8. The control unit 28 outputs the handling information output from the handling information search unit 27 to the output unit 30. In this case, the output unit 30 displays such as "Increase the injection amount of sodium hypochlorite."

Then, the equipment inspector determines the injection amount of sodium hypochlorite according to the handling information output to the output unit 30 (step S5), and based on the instruction of the injection amount, the current injection amount is determined. The work of decreasing or increasing the injection amount is performed (step S6). Then, since the number of coliform bacteria is equal to or less than the reference value, the treated water is discharged from the chlorine mixing basin 14 through the discharge pipe 15.

Incidentally, the control unit 28 responds to the search result searched by the countermeasure information search unit 27 when the state of water treatment tends to deteriorate based on the check history stored in the check history database 25. In addition to the output of coping information, the alarm unit 29 gives an alarm.

As described above, the countermeasure information corresponding to the inspection data and the reference value data stored in advance is output, and the injection of sodium hypochlorite is performed while satisfying the reference value of the coliform group number. Since I tried to increase or decrease the amount, without injecting sodium hypochlorite excessively,
It is possible to maintain operational quality.

The reference value for the number of coliform bacteria in the above-mentioned embodiment may be any value that can comply with the Water Pollution Control Law. Further, in the above-described embodiment, the information stored in the countermeasure information database 24 and the reference value database 23 is the data regarding the sewage treatment plant, but the reference data regarding other equipment is stored and the other data is stored. The inspection data may be received from the inspection terminal 16 that has inspected the equipment, and the above-described equipment inspection may be managed. Further, in the above-described embodiment, the case where the daily inspection items in the information stored in the countermeasure information database 24 and the reference value database 23 are inspected has been described, but the treated water of the sewage treatment plant is sent out. It is also possible to store the inspection items for the pump and the like and inspect the pump (daily inspection / periodic inspection).
