Discussion on treatment measures for black and odorous water
Taking the comprehensive water system treatment project in Linquan County as an example,the paper analyzes the present situation of black and odorous water bodies in Linquan County and the causes of high ammonia nitrogen concentration and low dissolved oxygen concentration are domestic sewage discharge,agricultural non-point source pollution and atmospheric subsidence pollution.Control measures such as the establishment of constructed wetlands,the establishment of buffer zone,joint operation of dam groups,river dredging,aeration and oxygen enrichment were put forward.After treatment,the characteristics of black and odorous water such as ammonia nitrogen content and dissolved oxygen were significantly improved,and the black and odorous water phenomenon was eliminated,which confirmed the feasibility of water engineering measures for the treatment of black and odorous water.
