The reclaimed water treatment equipment system adopts an integrated membrane bioreactor and a multiphase filter, utilizing the alternating action of aerobic and anaerobic bacterial communities to remove COD and ammonia nitrogen. It can treat domestic sewage to meet the national comprehensive sewage discharge standards, and the treated water can be directly discharged into natural water bodies. The significant advantage of this system is that it adopts a multi strain biochemical process, with no residual sludge discharge and simple operation; The effect is stable.
