Decentralized sewage treatment equipment

Technology process

   The decentralized sewage treatment equipment adopts AQ+ contact oxidation biochemical treatment process, and the equipment has three functional segments: anoxic, aerobic and sedimentation. In this process, special fillers are added into the equipment at each functional section to remove contaminants from the water by biofilm (microorganisms of various microorganisms) which adhere on the filler to grow.
   The main function of equipment for removal of pollutants is aerobic stage. The air pump continues to oxygenate the aerobic zone, so microorganisms growing on aerobic filler keep active. The continuous removal of microorganisms will achieve the function of purifying water quality. The equipment adopts chlorine disinfection and electrolytic phosphorus removal. The effluent quality reaches the first class B standard of “Discharge standard of pollutants for municipal wastewater treatment plant” (GB 18918-2002).
