The underground factory sewage treatment equipment adopts internationally advanced biological treatment technology, which can remove BOD5 COD、NH3-N， Stable and reliable technical performance, good processing effect, low investment, minimal land occupation, and easy maintenance.

Process principle of factory sewage treatment equipment products:

The design of underground factory sewage equipment is mainly aimed at the treatment of domestic sewage and similar industrial organic sewage. The main treatment method is to use a relatively mature biochemical treatment technology - contact oxidation method. The water quality parameters are designed according to the general domestic water quality, with an inlet bod of 200 mg/l and an outlet bod of 20mg/l. It consists of six parts: (1) primary sedimentation tank; (2) Contact oxidation tank; (3) Secondary sedimentation tank; (4) Disinfection pool and disinfection device; (5) Sludge tank; (6) Fan room, fan.

Product features of factory sewage treatment equipment:

1. Buried below the surface, the surface above the equipment can be used for greening or other purposes, without the need for building houses, heating, or insulation.

2. The secondary biological contact oxidation treatment process adopts push flow biological contact oxidation, which has a better treatment effect than fully mixed or two-stage series fully mixed biological contact oxidation tanks. And it has a smaller volume than activated sludge tanks, strong adaptability to water quality, good shock load resistance, stable effluent quality, and will not cause sludge expansion. A new type of elastic three-dimensional packing material is used in the pool, with a large specific surface area and easy biofilm formation and detachment by microorganisms. Under the same organic load conditions, it has a high removal rate of organic matter and can improve the solubility of oxygen in the air in water.

Application scope of factory sewage treatment equipment:

1. Hotels, food processing plants, restaurants, sanatoriums, hospitals, slaughterhouses, and office buildings;

2. Residential communities, villages, and towns;

3. Stations, airports, and seaports;

4. Factories, mines, troops, tourist attractions, scenic spots, etc.
