Rural Domestic Sewage Treatment Systems of Shanghai Songjiang in China

The rural domestic sewage treatment capacity in Shanghai Songjiang rural areas of China was relatively weak and hysteretic owing to the relatively unprogressive economic and social development. Here a field survey and analysis were conducted for the rural domestic sewage treatment systems of Songjiang. The results indicate that integrated facility, stabilization pond, soil infiltration-constructed wetland system, composite biological filter-constructed wetland system, combinatorial biofilter and interception in the sewer into the municipal sewer network are the main 6 domestic sewage treatment systems currently applied in the rural areas of Songjiang, and that the "soil infiltration-constructed wetland" and "combinatorial biofilter" systems, with obvious advantages, are promising to popularize in Songjiang rural areas.
