Process steps of domestic sewage treatment equipment

Process steps and structure of domestic sewage treatment equipment:

Buried integrated sewage treatment equipment can provide us with a clean living environment, so its use is becoming more and more extensive. However, when using this equipment, there are many points of attention that are particularly important. Let's introduce its specific operation process:

1. The commissioning personnel of the device must first turn on the water inlet valve and the water outlet valve, start the equipment water inlet and raise the water pump, and transport the sewage from the conditioning tank to the underground integrated sewage treatment equipment.

2. The underground integrated sewage treatment equipment used and debugged for the first time, when the water level reaches one-half of the height of the equipment, stop the water pumping, turn on the fan inlet valve, open the fan, and slowly open the fan outlet valve. After 48 hours of aeration in the contacting oxygen tank, the water-intake-increasing water pump is started to take the sewage to three quarters of the equipment, and then aeration into the tank for 24 hours.

3. The staff should touch the seasoning with their hands to see if there is a sticky feeling, and investigate the growth of microorganisms in the water body until the biofilm grows, before they can continue to transport sewage to the buried integrated sewage treatment equipment, the water volume should be gradually added to the design Water volume.

4. Investigate the growth of microorganisms in the water punctually. If any abnormalities are found, the water intake should be adjusted in time.

5. It is necessary to investigate the flow pattern of the water in the secondary sedimentation tank. The water collection of the effluent weir must be uniform. Usually, it is necessary to discharge the sludge every 24 hours. When the sludge is discharged, turn on the sludge discharge solenoid valve, and use the air lift method to remove the sewage in the secondary sedimentation tank. The mud is raised to the sludge pond.

6. The buried integrated sewage treatment equipment adds disinfectant in the disinfection tank as needed. The water from the secondary sedimentation tank passes through the disinfectant dosing tank, and the medicine is partially dissolved to reach the intention of disinfection. After the treated water stays in the clean water tank for about 0.5 hours, it reaches the discharge demand and can be discharged to the outside water body.

7. After debugging and normal operation of the underground integrated sewage treatment equipment, the system can enter active operation, and the operation of the water pump and fan can be switched to active operation on site.

In addition, in order to ensure the normal operation of the buried integrated sewage treatment equipment, we have to check the water quality of the equipment from time to time.
