1. Characteristics of buried integrated domestic sewage treatment equipment:

　　1. The underground integrated domestic sewage treatment equipment adopts mature biochemical treatment technology, which has good impact load resistance to adapt to the characteristics of water quality and water quantity.

　　2. The underground integrated domestic sewage treatment equipment adopts centralized control and automatic operation, which is easy to manage and maintain, and improves the stability of the system. reliability。

　　3. The underground integrated domestic sewage treatment equipment has good removal of organic matter in sewage and good nitrogen removal function to meet the requirements of discharge standards.

　　4. The buried integrated domestic sewage treatment equipment adopts a new type of high-efficiency biological filler, which has fast film hanging, long life and fast treatment effect.

2. Operation of buried integrated domestic sewage treatment equipment:

　　A: The secondary biological contact oxidation treatment process adopts biological contact oxidation, and the treatment effect is better than that of fully mixed and secondary tandem fully mixed biological contact oxidation cells. It is smaller than the activated sludge tank, has strong adaptability to water quality, good impact load resistance, relatively stable water quality, and will not produce sludge expansion. The new biological filler is used in the pool, which has a large specific surface area, and the microorganisms are easy to hang and remove the film, and the removal rate of organic matter is high under the same organic matter load condition.

　　B: The equipment host can bury it below the frozen layer, and the surface above the equipment host can do some greening or other things, without the need to build a house, heating, or insulation. The main unit can also be placed on the ground according to customer requirements.

　　C: The whole equipment processing system is equipped with a fully automatic electrical control system, which is safe and reliable, and generally does not need to be managed by special personnel, only occasional maintenance and maintenance of the equipment.

　　D: The biochemical tank adopts the biological contact oxidation method, the volume load of its filler is relatively low, the microorganisms are in their own oxidation stage, the mud production is small, and the mud is discharged once every three months (90 days) (suction or dehydrated into mud cake).

　　E: The deodorization method of the buried sewage treatment equipment adopts conventional high-altitude exhaust.
