Absract Combined process of biofiltraion-soil treat filtration treating polluted water and in situ stabilization treating river sediment has several fetures such as good treatment effect,low cost and no secondary pollution,which can be applied in treating inland river,urban river,lake,domestic sewage and so on. The results of detergency test in Zoujia river of Ningbo City show that all the indexes of water quality are greatly improved. The removal rate of COD and BOD5 are both above 80%,the removal rate of ammonia nitrogen is above 65% and the removal rate of phosphorus is above 75%. The cost of remediation of polluted rivers is 0. 018 yuan/t.
