Here, the operation of the batch type reaction tank 2 is defined as controlling the operation state of the batch type reaction tank 2, the amount of treated water flowing through the treated water discharge line 22, and the amount of sludge discharged through the sludge discharge line 23, The operation state of the reaction tank 2 is defined by including the anaerobic reaction time, anaerobic reaction time, and exhalation reaction time of the batch reactor. Thus, the control unit 3 drives the driving unit 32, which will be described below, to drive the operation of the batch type reaction tank 2.

The operation of the batch type reaction tank 2 is not shown in the drawing, but is performed by controlling various known configurations such as an aeration device, various valves, and a pump, and a detailed description thereof will be omitted.

The treatment water discharge line 22 includes the second sensor 221 on the other side of the batch type reaction tank 2, The water quality of the treated water, that is, the outflow water quality, is measured through the second sensor 221, and the measured value is transmitted to the controller 3. It is appropriate that the second sensor 221 includes a water quality sensor.

A third sensor 25 is provided in the batch type reaction tank 2 to measure the water quality and temperature of the inside of the batch type reaction tank 2 and to transmit the measurement result to the control device 3. It is appropriate that the third sensor 25 includes a water quality sensor and a temperature sensor.

The control device 3 is connected to the first to third sensors 211, 221 and 25 to accumulate and analyze the sensing data of the respective sensors to detect the operation state of the batch type reaction tank 2, 22, and the amount of sludge discharged through the sludge discharge line 23 are controlled.

2, the control device 3 of the present invention includes a data part 31, a driving part 32 and an analysis part 33 as shown in FIG. 2, and includes two embodiments for controlling the operation of the batch reaction tank 2 . Each embodiment is mutually complementary and can be used selectively.

First, the data unit 31 receives the influent water quality value and the flow rate value from the first sensor 211, derives the influent load, receives the outflow water quality value from the second sensor 221, (25), and the inflowing load and the outflowing water quality are converted into data by temperature.

That is, the data unit 31 provides the comparison data to the analyzing unit 33 to be described below by converting each influent load and each outflow water quality into data by temperature.

The analyzer 33 receives the real-time influent water quality value and the real-time flow rate value from the first sensor 211, derives the real-time influent load, and calculates the real-time influent load derived from the real- To obtain a real-time runoff water quality value. The real-time effluent quality value is derived from the comparison data obtained by data-by-temperature calculation of each influent load and each effluent quality in the data unit 31.

The analysis unit 33 determines the operation state of the batch type reaction tank 2 and the amount of treated water flowing out through the treated water discharge line 22 according to the real-time effluent water quality value thus derived. That is, the analysis unit 33 determines an appropriate operation state of the batch type reaction tank 2 and an amount of treated water outflow through the treated water discharge line 22 based on the derived real-time effluent water quality value.

Also, the analyzer 33 receives the real-time effluent quality value from the second sensor 221 and determines the sludge discharge amount through the sludge discharge line 23. In this case, the outflow water quality value by the second sensor 221 will be a value based on the SS or the like.
