advantages

1. Strong resistance to impact load, the average residence time of contact oxidation method is more than 6 hours.

2. It has the ability of denitrification and phosphorus removal, and can treat industrial wastewater, domestic sewage and urban sewage by adjusting the structure of equipment.

3. Most of the fillers in the contact oxidation tank are combined soft fillers with light weight, high strength, stable physical and chemical properties, large specific surface area, strong biofilm attachment capacity, and high contact efficiency between sewage and biofilm.

4. In the contact oxidation tank, the aerator is used for blast aeration to make the fiber bundle drift continuously, aeration is uniform, and microorganisms grow mature, which has the characteristics of activated sludge method.

5. The effluent quality is stable, the sludge yield is less and it is easy to handle.

6. Submersible pumps can be installed in equipment to reduce project investment.

7. The equipment can be installed on the ground or buried underground.When buried underground, the upper part can be used for afforestation, the factory area is less, the ground structure is less.

8, easy to complete automatic control, simple management operation.

9. The equipment can be connected to the car to make mobile integrated sewage treatment equipment.
