To Control The Operation Process Of Sewage Treatment Equipment
operators should first open the inlet valve and outlet valve, start the inlet water lifting pump, and transfer the sewage from the regulating pool to the sewage treatment equipment.
For equipment in initial use and debugging, when the water level reaches 1/2 of the height of sewage treatment equipment, operators stop the water pump and open the fan inlet valve to start the fan, as well as then slowly open the fan outlet valve to initiate the inlet water lifting pump to add sewage to 3/4 of the equipment after aerating in the oxidation pool for 48 hours, and then aerate in the pool for 24 hours.
Operators touch the filler by hand whether there is a sense of stickiness, and observe the growth of microorganisms in the water until the growth of a layer of orange biofilm on the filler, before continuous delivery of sewage to the sewage treatment equipment. The amount of water should be gradually increased to the designed amount of water.
Regularly observe the growth of microorganisms in the water, and control the amount of water intake to adjust if abnormal.
It is necessary to observe the water flow pattern of the secondary sedimentation tank and the water collection of the effluent weir. Generally, the sludge is discharged once every 24 hours. When discharging the sludge, the solenoid valve is opened and the sludge in the secondary sedimentation tank is elevated to the sludge tank by air stripping.
Sewage treatment equipment will take some disinfectant in disinfection pool. The water from the secondary sedimentation tank will react with the drug which is partially dissolved, to achieve disinfection. The treated water stays in the water box for about 0.5 hours, to meet the discharge requirements.
After commissioning and normal operation, the system can enter automatic operation. The operation of water pump and fan will be switched to automatic operation state. The electrical operation control cabinet is automatically controlled by PLC, the program has been programmed before the equipment leaves the factory, and there is no need to set it separately during operation.
Users should test the water quality in accordance with the environmental protection discharge requirements from time to time to ensure the normal operation of sewage treatment equipment.
