1. The ability to resist impact load is strong, and the average residence time of contact oxidation method is more than 6 hours.

2, with the ability of nitrogen and phosphorus removal, and can adjust the structure of equipment, to deal with industrial wastewater, domestic sewage, urban sewage capacity.

3. The fillers in the contact oxidation tank are mostly composed of soft fillers, which are light weight, high strength, stable in physical and chemical properties, large specific surface area, strong biofilm adhesion ability, and high contact efficiency between sewage and biofilm.

4. In the contact oxidation tank, aeration is used to conduct blast aeration so that the fiber bundles are continuously drifted, the aeration is uniform, and the microorganisms are matured and matured, which is characterized by the activated sludge method.

5. The effluent water quality is stable, sludge production is small and it is easy to handle.

6. The submersible pump can be installed in the equipment to reduce the investment in the project.

7, equipment can be located on the ground, but also buried in the ground. When buried in the ground, the upper part can be used for greening. The factory area is small and there are few ground structures.

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

9, the device can be connected to the car made of mobile integrated sewage treatment equipment.
