Example of Rural Domestic Sewage Treatment Project
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+A2O+artificial wetland"is designed for application,in which the A2/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.
