[0021] like Figure 1 As shown,

[0022] As an optional embodiment,

[0023] A sewage treatment monitoring system comprises a sewage treatment device 1, wherein the discharge end of the sewage treatment device 1 is connected to a sewage filtration treatment device 2 through a first pipe fitting, and the discharge end of the sewage filtration treatment device 2 is connected to a sewage sedimentation treatment device 3 through a second pipe fitting; the sewage sedimentation treatment device 3 is connected to the sewage filtration treatment device 2 through a third pipe fitting, and the third pipe fitting is sequentially connected to a filter 4, a pump body 5 and a first solenoid valve 6, the first pipe fitting is installed with a third solenoid valve 8, and the second pipe fitting is installed with a second solenoid valve 7, a PLC controller 16 is installed on the sewage filtration treatment device 2, and the PLC controller 16 is electrically connected to the first solenoid valve 6, the second solenoid valve 7 and the third solenoid valve 8 respectively, and the sewage filtration treatment device 2 comprises a tank body, an electric heater 14 and three temperature sensors 15, wherein the three temperature sensors 15 are respectively located at the middle position of the left part of the tank body, the middle position of the right part of the tank body and the middle position of the top, and the three temperature sensors 15 and the electric heater 14 are all electrically connected to the PLC controller 16.

[0024] In the above structure, the sewage to be treated flows into the sewage treatment equipment 1, and after being treated by the sewage treatment equipment 1, it flows into the sewage filtration treatment equipment, and the sewage filtration treatment equipment further treats the inflowing sewage. Finally, the sewage in the sewage filtration treatment equipment after treatment enters the sewage sedimentation treatment equipment for sedimentation operation, so as to realize sewage purification treatment and achieve the purpose of reasonable sewage discharge;

[0025] The sewage treatment equipment 1 is provided with a radiation detector for detecting the radioactive activity of the sewage. If the radiation detector detects that the radioactive activity of the sewage is higher than the index value, a chemical elimination method including a chemical neutralization method and a chemical adsorption method is adopted, wherein chemical substances are used to react chemically with the nuclear radiation substances to convert them into harmless substances, such as using an adsorbent such as activated carbon to adsorb the radioactive substances on the surface, and then the substances are centrally processed until the radiation detector detects that the radioactive activity of the sewage reaches below the index value. Then, the PLC controller 16 controls the third solenoid valve 8 to open the first pipeline passage, so that the sewage can be discharged into the sewage filtration treatment equipment 2;

[0026] When entering the sewage filtering and treating device 2, the sewage filtering and treating device 2 filters the sewage. During the filtering process, the sewage can be heated by the electric heater 14, which can improve the fluidity of the internal liquid and prevent the sewage from sticking at low temperature. In addition, in order to further detect the temperature changes of various parts of the sewage, temperature detection sensors are installed at the middle position of the left part of the tank body, the middle position of the right part of the tank body, and the middle position of the top. The temperature sensor can detect the local temperature. Since three temperature sensors are used, when a temperature sensor is damaged and fails, the remaining two temperature sensors can still effectively control the heating temperature, with high temperature measurement accuracy. Heating can disinfect and sterilize the sewage, and can further improve the fluidity of the sewage and prevent the wastewater containing oil substances in the low-temperature sewage from cooling and condensing.

[0027] When entering the sewage sedimentation treatment equipment 3, the sewage is further cooled and placed for stratification treatment; then the supernatant is discharged.

[0028] Based on the first embodiment, Figure 1 As shown:

The set weighing hopper 17 can control the amount of the input material to achieve particle control of the input amount of the input material. Subsequently, the PLC controller 16 can control the opening and closing of the sixth solenoid valve 12 to achieve the purpose of automatically inputting the input material into the sewage treatment equipment 1.

[0031] As a preferred solution, a fourth solenoid valve 9 is installed on the sewage treatment equipment 1, and the liquid inlet end of the fourth solenoid valve 9 is connected to a clean water pipeline. The fourth solenoid valve 9 is electrically connected to the PLC controller 16. The fourth solenoid valve 9 is selected to open the clean water pipeline to connect with the sewage treatment equipment 1, and the radioactive activity of the sewage can be reduced by dilution. Conversely, clean water can be automatically connected to facilitate subsequent cleaning of the sewage treatment equipment. The fourth solenoid valve can be subsequently controlled to open and close by the PLC controller 16.

[0032] As a preferred solution, a fifth solenoid valve 10 is installed on the sewage treatment equipment 1, and the liquid inlet end of the fifth solenoid valve 10 is connected to a flow meter 11, and the liquid inlet end of the flow meter 11 is connected to a sewage pipe. The fifth solenoid valve 10 is electrically connected to the PLC controller 16. In order to further control the amount of sewage entering the sewage treatment equipment 1, the flow meter 11 is designed to control the sewage flow rate, and the fifth solenoid valve is controlled to open and close by the PLC controller to control whether the sewage is discharged into the sewage treatment equipment 1.

[0033] As a preferred solution, the second pipe fitting is connected to the third pipe fitting by a tee pipe, and the tee pipe is located on the second pipe fitting between the second solenoid valve 7 and the sewage filtering treatment equipment 2. The second solenoid valve 7 can be used to cut off the sewage in the sewage filtering treatment equipment 2 from being discharged into the sewage sedimentation treatment equipment 3. The second solenoid valve 7 is closed and the first solenoid valve 6 is opened. The pump body 5 flows the sewage sedimentation treatment equipment 3 into the sewage filtering treatment equipment. The upper clear liquid inside the sewage sedimentation treatment equipment 3 can be discharged into the sewage filtering treatment equipment 2, and the interior of the sewage filtering treatment equipment 2 is backwashed to clean the sewage filtering treatment equipment 2. At the same time, the filter 4 can filter the sewage flowing through to avoid sewage clogging the pump body.

[0034] As a preferred solution, the PLC controller 16 includes a data input / output module, a data processing module, a memory card and a CPU module, wherein the PLC controller 16 mainly adopts a PLC programmable controller, and is also equipped with an AD converter to achieve the effect of converting analog signals into digital signals. The data input / output module can adopt a DAM-3025D data acquisition module, and the memory card stores the execution program, specifically a GCAN-PLC series programmable master control module.

[0035] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
