Comprehensive evaluation system and application of quality and efficiency improvement of wastewater treatment
Currently,the influent water concentrations of BOD5 and the centralized collection rate of municipal sewage pollutants are the mainly evaluations of quality and efficiency improve-ment of wastewater treatment.Based on four evaluation index:influent water concentrations of BOD5,the ratio of sewage to water supply,the ratio of water treatment capacity on rainy days to clear days、high risk rivers,this paper established comprehensive evaluation system of quality and efficiency improvement of wastewater treatment,and it has been applied in Shenzhen.The practice shows that evaluation system is capable to objectively and fairly reflect the efficiency of sewage col-lection,may also can guide to identify and rectify issues.The results can not only support the as-sessment evaluation,but also indicate the direction for future work.
