Based on summarizing a lot of experiment results,the paper expounded the main removal mechanisms and processes of nitrogen(N),phosphorous(P),and organic matter in constructed rapid infiltration(CRI) as well as the limiting factors during the purification processes.In addition,the major operating parameters were introduced,the impacts of filter material,temperature,and water distribution mode on purifying efficiency were summarized and the domestic progresses of CRI improvement at present were summarized in ...
