How to avoid the embarrassment caused by the "neighbor avoidance effect" in the construction of sewage treatment plants, which may affect the environmental quality but are necessary facilities for urban life? Jiading solved this problem by building a sinking sewage treatment plant. Jiading Nanxiang sewage treatment plant adopts the all underground integrated improved AAO Technology (anaerobic anoxic oxic, i.e. "anaerobic anoxic aerobic method", which is a sewage treatment process). The effluent quality implements the national first-class a discharge standard. An urban science popularization hydrophilic park integrating culture, science popularization and leisure will be built in the upper part of the sewage treatment plant. A water science and Technology Museum will be built in the park Sports Square and so on, people will not feel that there is a sewage treatment plant under their feet.
