城镇生活污水处理工艺的改进及效果评价

Improvement and Effect Evaluation of Urban Domestic Sewage Treatment Process

为响应国家对生活、生产污水更加严格的标准要求,解决城镇污水当前处理工艺的出水水质与《城镇污水厂污染物排放标准》的一级A标准存在一定差距的问题,在对当前地区城镇生活污水进水和出水水质现状进行分析的基础上,在当前曝气生物滤池过滤工艺的基础上增加BAF工艺进行改造,并对改造后工艺的处理效果进行评价。

In order to respond to the stricter national standard requirements for domestic and production sewage,and solve the problem that there is a certain gap between the effluent quality of the current urban sewage treatment process and the first-class a standard in the pollutant discharge standard for urban sewage treatment plants,based on the analysis of the current situation of the inlet and outlet water quality of urban domestic sewage in the region,the treatment effect of the improved process was evaluated.
