某农村生活污水治理工程实例

Example of Rural Domestic Sewage Treatment Project

针对农村生活污水水质特点,结合某农村生活污水实际情况,设计采用了“格栅池+调节池+A2O+人工湿地”组合工艺,其中生物处理段采用了A2O生物接触氧化工艺,湿地采用了垂直流+水平流人工湿地工艺。污水处理站点建成后,在设计进水水质的条件下,出水水质能稳定达到DB32/3462—2020一级A标准。该工艺对污染物处理效果好,可作为农村生活污水高标准治理技术进行推广。

Based on the water quality characteristics of rural domestic sewage and combined with the actual situation of a rural domestic sewage,the composite process of"grid tank+regulating tank+A^(2)0+artificial wetland"is designed for application,in which the A^(2)/O biological contact oxidation process is used in the biological treatment section,and the vertical flow+horizontal flow artificial wetland process is applied in the wetland.After the construction of the sewage treatment station,under the designed influent water quality conditions,the quality of effluent can stably reached the first level A criteria of DB32/3462-2020.This process has good pollutant treatment effect and can be promoted as a high standard treatment technology for rural domestic sewage.
