1.Product Description
1) Waste Water Treatment is an aboveground plant which adopts the advanced Biological technology and the company's scientific research and engineering practice result.

2) it can effectively remove BOD5,COD and NH3-N. The device is characterized by the stable performance, effective treatment, economical investment, automatic operation, convenience of maintenance and small occupying space.

3) There is no need for construction, neither heating and heat preservation.

4) The surface can be used as green land or square land.It also can be placed on ground based on client's requirement.

5) As the most efficient sewage treatment device, it is widely used in treating the sewage in the area of senior hotels, village districts and residential districts, etc.

5) The water after treatment not only would meet the national emission standards. but also can be used to irrigation or re-used.

1.3 Working Principle
1) The sewage enters the artificial grille first, and the solid waste in the domestic sewage is initially removed by the grille

2) Then enters the regulating tank to adjust the water quality and quantity, and then is pumped to the Anaerobic tank by the lifting pump, and the organic matter in the sewage is decomposed, metabolized and digested by the anaerobic bacteria, so that the organic matter content in the sewage is greatly reduced. 

3) Then enters teh anoxic tank and the submersible agitator is arranged in the anoxic tank to perform nitrification and denitrification. Combined with aerobic denitrification and dephosphorization, the macromolecular organic particles are decomposed into small molecular organic particles, which can improve the biodegradability of the wastewater.

4) Then the sewage flows into the aerobic tank and conducts aerobic biochemical reactions. The substance is degraded by biological oxidation

5) And the effluent flows to the second setting tank for solid-liquid separation. The supernatant of the second setting tank flows into the clear water tank

6) The sludge in the second setting tank is returned to the Anoxic tank by the sludge return pump, and
the other part of the sludge is sedimented by itself to the sludge tank.

7)The sludge in the sludge tank is periodically dewatered by the sludge dewatering machine. The sewage sludge supernatant is returned to the conditioning tank by the mixed liquid reflux pump for further treatment.




1.4 Advantage
1)Compact design, which is easy to transport.

2) Integrated device, no need construction, which is easy to be installed.

3)Full Automatic machine, which is easy to operate and maintain.

4)Can be fixed on underground, which can save room and earth. 

5)Don't need additional construction, the total cost is small.
