Abstract: The progress on water purification effect of aquatic plants,porous concrete and the joint application of aquatic plants and porous concrete are reviewed separately;the advantage of using aquatic plants to purify sewage and the deficiencies in existing research are analyzed,and the prospect of the combined application of aquatic plants and porous concrete for the purification of waste water are pointed out. According to the geographical environment of different regions,it is pointed out that the combining application of porous concrete with the ecosystem formed by varieties of aquatic organisms is a trend,and the overall water purification effect of the combined system is the focus of future research. Finally the problems that need to be solved in the future are pointed out.
