1. Low investment
2. Biochemical treatment method
3. Convenient for management

1, impact resistant load ability. Contact oxidation in the average residence time more than six hours;

2 with nitrogen, phosphorus ability, and can adjust the equipment to deal with the structure of industrial wastewater, sewage, urban sewage capability;

3, contact oxidation in the pool for the combination of packing more soft filler, qualitative light, high strength, physical and chemical stability, high spicific surface adhesion ability strong, biofilm, sewage and biofilm contact high efficiency;

4, contact oxidation in the pool are using aerator, drum wind aeration fibre bundle moved, aeration constantly bleaching evenly, microbial growth mature, has activated sludge characteristic;

5, outlet water quality stable, and easy to deal with less sludge production;

Six, can put into equipment submersible pumps and cut down engineering investment; among

7, equipment can be set in the ground, can also be buried underground. Buried underground, the upper covered can be used for afforestation, the factory covers an area of less, ground structures is less;

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