Efficient and energy-saving domestic sewage treatment process with double reverse biological membranes

The invention provides an efficient and energy-saving domestic sewage treatment process with double reverse biological membranes, which is characterized in that the domestic sewage treatment process comprises an anoxic tank, an aerobic tank and a sedimentation tank which are connected in sequence, the reverse biological membranes are placed in the anoxic tank, and the reverse biological membranes comprise breathable hydrophobic membranes and microbial membranes growing on the surfaces of the breathable hydrophobic membranes in an attached manner; the volume of the anoxic tank is larger than that of the aerobic tank. The device has the characteristics of high oxygen utilization rate, high pollutant removal efficiency and the like, and is small in aeration rate, low in energy consumption and convenient to manage. 本发明提出了一种高效节能的双反向生物膜生活污水处理工艺，其特征在于：包括依次相连的缺氧池、好氧池和沉淀池，所述缺氧池内放置反向生物膜，所述反向生物膜包括透气疏水膜和附着生长在透气疏水膜表面的微生物膜；所述缺氧池的容积大于好氧池。具有氧气利用率高，污染物去除效率高等特点，曝气量小，能耗低，方便管理。
