Water Treatment Technology of Rural Sewage Pond

A set of related technologies for water treatment of rural sewage pond, namely, pretreatment + hypoxia biochemical + compound constructed wetland, was studied．Sewage pond was separated into three zones, and rural sewage passed through pretreatment zone, anoxic biochemical zone and aquatic plant stabilization zone successively．Through filtration, coagulation, microbial degradation, wetland substrate adsorption and plant absorption, water body of sewage pond can be efficiently purified and rural ecological environment can be improved．
