With the rapid economic development and rapid expansion of cities, small rivers around the city are subject to different levels of pollution and river ecosystems are seriously damaged. At present, there are mainly physical rehabilitation technology, chemical remediation technology and biological remediation technology for the control of riverpollution. Low transparency, low dissolved oxygen and high content of suspended matter and other issues are widespread existed in polluted urban rivers which severely limited the restoration technology of aquatic animals and plants for ecological restoration. Artificial aquatic plants technology is the emerging bio—enhanced remediation technology which can not be limited by the factors of water transparency and suspended matter and unforeseen pollution load and has the characteristics of low in investment. effective, and no secondary pollution.In this paper, a new type of artificial plants control gate filler was tried to build for severe or moderate urban rivers pollution. The feasibility program for urban polluted river was tried out by artificial plants and other biological remediation technology.Through the static test, the fill material of artificial plants and architecture were selected. Carpet of the average removal rate of the COD?ammonianitrogen?TP? TN were 90%?81%?90%?88%.which can inhibit the growth of algae in water. In the simulation of dynamic channel bioreactor experiment, we find the optimum condition for biodegradation of wastewater was DO 4-4.5mg/L, HTR 24 hours. According to the reality pollution of DaLi Bo Luo river, ecological restoration program was made by artificial plant technology, plant technology and oxygenation technology Control measures were made to promote the development of local ecology, society and economy.
