Embodiment 1

[0053] see figure 1 , figure 1 It is a structural schematic diagram of a sewage treatment control system provided in the embodiment of this application. Depend on figure 1 It can be seen that the sewage treatment control system in this application mainly includes: a data acquisition module 1, a PLC controller 2, a cloud computing big data analysis platform 3 and a communication module 4. Wherein, the data acquisition module 1 is set in the integrated sewage treatment equipment, and is used for collecting COD value, ammonia nitrogen value of water in the sewage treatment process, power parameters and water flow of the integrated sewage treatment equipment. The PLC controller 2 is connected to the cloud computing big data analysis platform 3 through the communication module 4, and the PLC controller 2 is also connected to the electric valve of the dosing tank in the integrated sewage treatment equipment for the data collection module 1. Perform preliminary processing and on-s...

Embodiment 2

[0057] exist figure 1 On the basis of the illustrated embodiment see figure 2 , figure 2 It is a schematic structural diagram of another sewage treatment control system provided in the embodiment of the present application. Depend on figure 2 It can be seen that the data acquisition module 1 in this embodiment mainly includes: an influent COD monitor 11, an influent ammonia nitrogen monitor 12, an effluent COD monitor 13, an effluent ammonia nitrogen monitor 14, an aerobic pool COD monitor 15, an aerobic pool Ammonia nitrogen monitor 16, water inlet flow meter 17, water outlet flow meter 18 and electric energy meter 19.

[0058] The inlet water COD monitor 11, the inlet water ammonia nitrogen monitor 12 and the inlet water flowmeter 17 are all arranged on the pipeline where the sewage enters the adjustment tank, that is, the pipeline upstream of the adjustment tank. In this embodiment, in order to avoid the interference of the water inlet flowmeter 17 by other equipment...

Embodiment 3

[0069] exist figure 1 and figure 2 On the basis of the illustrated embodiment see image 3 , image 3 It is a schematic flow chart of a sewage treatment method provided in the embodiment of this application. Depend on image 3 It can be seen that the sewage treatment method in this implementation mainly includes the following processes:

[0070] S1: Obtain the COD value of the water before sewage treatment, the COD value of the water in the aerobic pool, and the COD value of the water after sewage treatment.

[0071] In this implementation, after the COD values ​​of water in different water treatment stages are obtained, they are also stored and real-time curves are generated for intuitive understanding.

[0072] S2: Determine whether the COD value of the water before sewage treatment is ≤ the COD reference value of the influent water, whether the COD value of the water in the aerobic pool is ≤ the COD reference value of the water in the aerobic pool, and whether the COD...

Abstract

The invention relates to a sewage processing control system and a sewage processing method. The control system comprises a data collection module, a PLC (Programmable Logic Controller), a cloud computing big data analysis platform and a communication module. The method comprises the following steps: obtaining the COD (Chemical Oxygen Demand) value of water before sewage processing, the COD value of the water in an aerobic tank and the COD value of the water after sewage processing; judging whether the COD value of the water before sewage processing is smaller than or equal to an incoming waterCOD reference value or not, whether the COD value of the water in the aerobic tank is smaller than or equal to the COD reference value in the aerobic tank or not, and whether the COD value of the water after sewage processing is smaller than or equal to an effluent COD reference value or not; if so, judging whether sewage processing is normal or not, otherwise, judging that sewage processing is abnormal, and in terms of the two abnormal situations, controlling the electrically operated valve of a medicine adding tank to be started or stopped through controlling a variable frequency fan or controlling the PLC. Through the control system, water quality can be monitored in real time so as to effectively improve the purification degree of the water quality. In addition, various pieces of monitoring data of sewage processing integration equipment can be collected so as to bring convenience for workers to carry out analysis and calling at any time.

Description

1.1 Technical field [0001] The present application relates to the technical field of sewage treatment, in particular to a sewage treatment control system and a sewage treatment method. 1.2 Background technology [0002] In the field of sewage treatment technology, integrated sewage treatment equipment is usually used for water treatment. Integrated sewage treatment equipment usually includes: regulating pool, anaerobic pool, anoxic pool, aerobic pool, secondary sedimentation pool, water distribution pool, clear water pool, Various water pumps, dosing tanks and frequency conversion fans. Among them, the sewage enters the regulating pool through the pipeline, and the regulating pool transports the water to the anaerobic pool through the pipeline through the lifting pump, the anaerobic pool flows the water into the anoxic pool through the pipeline, and the anoxic pool flows into the aerobic pool through the pipeline The nitrification liquid return pump is used to drive the wat...
