Abstract
Combined with the natural conditions of Zhouzhuang Village,Tianjin City,and its sewage quality and quantity,and considering the sewage discharge standard and downstream requirement for wastewater,an unpowered hybrid constructed wetland wastewater treatment system was designed and constructed. Its capacity is 30 m3/d. The operation result shows that the effluent can meet the second class criteria specified in the Integrated Wastewater Discharge Standard (GB 8978-1996),and can be used in the fish pond.
