Adopting high efficient biological treatment technology, integrating the removal of COD, BOD, NH3-N, TN, TP, SS and other pollution indicators in one, according to the concentration of pollutants and treatment requirements for the reasonable design of the process unit, to achieve the purpose of treatment results and cost savings, for different customer needs, relying on the integration, modularization of the process section, can be flexibly configured, rapid response; at the same time, the equipment is highly integrated design, can contain anaerobic, anoxic, aerobic and other process sections, with high efficiency phosphorus deamination. At the same time, the highly integrated design of the equipment can contain anaerobic, anoxic, aerobic and other process sections, with efficient phosphorus removal and deammonia effect. It is widely used in sewage treatment of domestic, medical, butchery, pharmaceutical and other industries.
