Survey of Rural Domestic Sewage Treatment Systems of Songjiang District in Shanghai, China

Abstract

Due to the relatively unprogressive economic and social development of Songjiang rural areas of Shanghai city in China, the degree of rural domestic sewage treatment was relatively weak and hysteretic. The rural sewage treatment systems of Songjiang district were investigated through field survey. Finally, the systems of soil infiltration-constructed wetland and combinatorial biofilter, with obvious advantages, were proposed to popularize in Songjiang rural areas more suitably.
