Analysis on the Operation Status and Treatment Effects of Town Sewage Treatment Facilities in the Dianchi Lake Basin

Through investigating of current situation of town sewage treatment facilities,and monitoring and analyzing the effluent quality in the Dianchi Lake basin,this paper made a comparative analysis of eight town sewage treatment technologies in terms of the effect of removing contaminants,impact resistance,operational stability and so forth,and provided technical support and scientific basis to further increase the operation efficiency of town sewage treatment facilities and improve effluent quality. Man-made wetland,as the only purifying engineering process needed to be promoted. The CASS and advanced processing (filtration fabric + disinfectant) was recommended as the priority choice for future new sewage treatment facility.
