A detailed introduction to the processing technology of the integrated wastewater treatment equipment for residential communities

1. Geshan

The grid is mainly used to block the solid suspended solids in the wastewater to ensure the normal operation of the building after the treatment and to reasonably relieve the treatment load, providing a guarantee for the long-term normal operation of the system.

2. Horizontal flow sedimentation tank or fiberglass septic tank

Due to the fact that the water body and water volume vary at different times, the total flow during peak periods is generally 2 to 8 times the average output. Therefore, in order to ensure the continuous and stable operation of the sewage treatment system and to adjust the water flow and homogenize the water body, a horizontal flow sedimentation tank is designed. The design scheme of this integrated wastewater treatment equipment is reasonable, and its capacity is generally 6 to 10 times the average output. The horizontal flow sedimentation tank is embedded with submersible sewage pumps and backflow countermeasures. Additionally, a hydrolysis acidification tank system is set up to carry out a pre-hydrolysis acidification tank to ensure a certain rated flow rate is increased to the stability of domestic sewage treatment equipment and subsequent treatment. Two QW type submersible sewage pumps are used for sewage lift pumps.

3. Sewage treatment equipment

The processing technology selects the WSZ domestic sewage treatment equipment. This integrated wastewater treatment equipment is mainly used for domestic sewage treatment and the treatment of industrial organic wastewater similar to this type. The key treatment method adopts the currently relatively mature biochemical treatment technology - contact oxidation method.

(1) Class A biochemical tank

To keep the dissolved oxygen in the A-level biochemical tank at around 0.5 mg/ s, A pore hydrolysis acidification tank is selected for the tank. The packing material for the A-level biochemical tank adopts A new type of ductile three-dimensional packing with a height-to-width ratio of 2.

0 meters. This type of packing material has the advantages of being less prone to clogging, being relatively light in weight, having a large specific surface area, and maintaining a stable treatment effect. Moreover, it is easy to maintain and replace, with a retention time of ≥3 to 5 hours.
