我国城镇污水处理厂建设运行概况及存在问题分析

摘要

According to"annual statistical yearbook of urban drainage in 2016",the Chinese municipal waste water treatment plants(WWTPs)were analyzed through several aspects,such as the overall treatment conditions,the capacity,electrical power consumption,the technical proces-ses,in let COD concentration and so on.Also,a comparison between 2010 and 2015 has been made.Besides that,the problems existing in wastewater treatment plants construction and opera-tion w ere discussed,some recommendations have been made to improve the construction and opera-tion level of WWTPs.%以《2016年城镇排水统计年鉴》为主要依据,对我国城镇排水和污水处理情况、城镇污水处理厂设计处理能力、运行负荷率、单位电耗、采用处理工艺、进水COD水质等关键数据进行分析,对城镇污水处理厂建设和运行中存在的问题进行了分析,可为"十三五"及今后一段时期提高城镇污水处理厂建设和运行水平、改善水环境质量提供指导.
