1. The installation and commissioning personnel first open the inlet and outlet valves, start the equipment inlet lift pump, and transport the sewage from the regulating tank (which can be used for civil engineering) to the buried domestic sewage treatment equipment for operation.
2. For the equipment used and debugged for the first time, when the water level reaches the height of12 of the equipment, stop the water inlet of the pump, open the water inlet valve of the fan, slowly open the water outlet valve of the fan, aerate the contact oxidation tank for 48 hours, then start the water inlet lift pump to add 3/4 of the sewage into the equipment and aerate the tank for 24 hours.
3. The staff should touch the filler with their hands to see if it feels sticky, and observe the growth of microorganisms in the water body at the same time, until an orange biofilm grows on the filler, the sewage can be continuously transported to the equipment, and the water volume should be gradually increased to the design water volume.
4, regularly observe the growth of microorganisms in the water, found abnormal should be timely control of water to adjust.
5. Observe the flow pattern of the secondary sedimentation tank. The outlet weir must be uniform, and sludge must be discharged once every 24 hours. When discharging sludge, open the sludge discharge solenoid valve and lift the sludge in the secondary sedimentation tank to the sludge tank by blowing off.
6. Buried sewage treatment and equipment need to add disinfectants (chlorine wafers, etc.). ) put it in a disinfection pool. The water from the secondary sedimentation tank passes through disinfectants and medicine cans, and the medicine is partially dissolved, thus achieving the purpose of disinfection. After the treated water stays in the clean water pool for 0.5 hours, it meets the discharge requirements and can be discharged to the external receiving water body.
7. After the equipment is debugged and operated normally, the system can enter into automatic operation. On-site pumps and fans are switched to automatic operation. Because the electric operation control cabinet adopts PLC automatic control program, it has been programmed before the equipment leaves the factory (usually switching once per shift), so it does not need to be set separately when operating.
8. Users should regularly test the effluent quality according to the requirements of environmental protection discharge to ensure the normal operation of buried sewage treatment equipment.
