Project Profile

Powerless Disposal System of Rural Domestic Sewage: The system is suitable for dispersive disposal of domestic sewage from kitchen, wash machine and toilet. Its principle is to assemble sewage to sewage disposal system by tubes based on specific landform. The system consists of three pools, which are called (1)Sedimentation pool (with its main use of water regulation, water quality uniform and initial precipitation, anaerobic fermentation and degrading); (2)Anaerobic fermentation pool (with its main use of degrading organic pollution in polluted water and sterilizing harmful microorganisms such as E.coli; (3)Plant-soil percolation pool (with its main use of absorbing N, P and organic compounds by anaerobic fermentation of microorganisms, the absorbency of plant and permeability of soil, thus water quality can reach prescribed standards for pollutants discharge).
