Abstract
The biological purification tank combined of artificial wetland technique and the bio-contact oxidation method was applied for malodorous river water in central urban region of Shanghai City. The average removal rates of Pontederia cordata L filling filtering tank on system BOD5, CODCr, NH3-N and TP were 37.0%, 34.8%, 34.7%, 26.7% respectively, the removal rates were higher than the filling purification tank. The devoted rates of Pontederia cordata L assimilate utilization on N, P were 8.92% and 25.24% respectively, and formed good mutually beneficial and intergrowth relations. Through the analysis of biofilm, the ecosystem of water body has been remediated rapidly during the experiment.
