A set of related technologies for water treatment of rural sewage pond,namely,pretreatment + hypoxia biochemical + com-pound 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 degrada-tion,wetland substrate adsorption and plant absorption,water body of sewage pond can be efficiently purified and rural ecological envir-onment can be improved.
