This regulation is a technical document and basis for guiding sewage treatment and normal operation. It is applicable to the water treatment operation staff of sewage treatment plants, as well as to management, laboratory, technical, and maintenance inspection personnel. It can also be used as a reference for other relevant personnel.
Employees of sewage treatment plants should ensure that all facilities in the station are in good condition and in good working condition. Any malfunctions should be promptly resolved, and they are not allowed to work with illnesses or violate regulations. Strictly implement this regulation and relevant regulations of the enterprise, fulfill our duties and responsibilities, achieve safe operation, and meet the requirements of wastewater treatment.
1. One set of manual grid in the grid pool can automatically intercept various large solid impurities in the sewage. The sewage station staff regularly check the condition of the grid, manually clean the slag, and regularly transport the slag outside.
2. The regulating tank is used to collect sewage, balance water quantity and quality. One lifting pump is installed in the tank to lift the sewage into the integrated sewage treatment equipment. One liquid level float ball is installed to control the start and stop of the lifting pump through high and low liquid levels. ① Operation content, methods, and control indicators: The control mode of the sewage lifting pump is divided into manual and automatic control. When manually controlled, the lifting pump can be manually started and stopped. When turned to automatic control, the lifting pump can operate automatically under the control of the liquid level float. ② Safety precautions and emergency handling of malfunctions: Operators should regularly observe the operation status of the lifting pump, promptly eliminate any abnormalities, and communicate with the manufacturer to solve any other difficult problems.
3. Biochemical processing unit
The biochemical treatment unit is mainly divided into three parts: anoxic tank, aerobic tank, MBR membrane tank, which is equipped with biological packing and aeration device. Microorganisms in the tank attach to the packing and grow to form biofilm. Hollow fiber membrane modules are installed in the MBR membrane tank to deeply treat sewage. In different areas, sewage is purified under the action of different microorganisms, and COD, BOD, ammonia nitrogen and other indicators are removed.
Operation content, methods, control indicators, and precautions: ① During the initial sludge cultivation, the growth of biofilm on the packing material should be regularly observed. ② After the equipment is running normally, pay attention to the growth of microorganisms to prevent abnormal conditions such as sludge floating and sludge swelling.

In the MBR membrane tank, membrane components replace the secondary sedimentation tank in the traditional activated sludge process, intercepting a large number of microbial communities in the biological system, promoting the aggregation of microbial communities and biological species in the system, and improving the sewage treatment capacity and efficiency. Part of the sludge flows back to the hydrolysis acidification tank to increase the sludge concentration in the tank, while the other part is discharged to the sludge tank for external treatment.
Operation content, methods, control indicators and precautions:
① Adjust the starting frequency and time of the reflux pump according to the operation status of the sewage station. To prevent affecting the sedimentation effect, both the reflux pump and sludge pump should not be started or stopped frequently. ② MBR membrane components require regular maintenance, and cleaning solutions should be used regularly to backwash the MBR membrane according to its operating conditions, decompose organic matter attached to the membrane surface, restore membrane differential pressure, and increase its service life.
Other precautions:
1. Seriously abide by the safety operation regulations, especially during the inspection of water tanks and equipment, be highly concentrated and do not work outside the safety protection fence;
2. Before the maintenance of mechanical and electrical equipment, the power supply should be cut off and a "non compliant closing" sign should be hung at the switch in the central control room;
3. Sewage and sludge should be strictly disinfected according to regulations, and should not be casually lifted or stacked;
4. All sewage treatment agents, raw materials, etc. must not come into contact with domestic drinking water sources and food to prevent poisoning accidents.

Operating Procedures for Sludge Dehydration Workshop Process
In order to better utilize the equipment, ensure that the sludge treatment meets the design and corresponding discharge standards, and meet the production requirements of the entire plant, the process operation instructions are provided.
Operators should strive to learn this instruction and continuously summarize their experience in production practice, propose rational suggestions for sludge treatment, and improve the level of sludge treatment. During the sludge treatment process, operators should closely monitor the operation of equipment and the effectiveness of sludge treatment, and record in detail the operation process and any malfunctions encountered during operation.
1. After the centrifuge is started and reaches zui high speed, adjust the basic speed difference, control slope and control starting point.
2. When the moisture content of the mud cake is too high and the separation liquid is clear, perform the following operation:
⑴ Reduce the speed difference. (Slightly higher moisture content)
⑵ Adjust the clear liquid weir plate or lower the feed rate. (Slightly higher moisture content)
⑶ Increase the dosage of flocculant. (High moisture content)
⑷ Reduce the speed difference and increase the dosage of flocculant. (High moisture content)
3. When the moisture content of the mud cake is too high and cannot be adjusted through step (2), check whether the mud meets the dewatering requirements of the centrifuge and adjust the mud before dewatering.
