Based on the national tenth five magnitude project — Suzhou City Water Environment Improvement and Synthesize Demonstration item, we carried out the static simulation test and the dynamic simulation test under the condition of heavy pollution loading rate and low transparency and dissolved oxygen in polluted river of suzhou ancient city district. These investigations were on the base of the formers' work. We analyzed the purification effects and rules of plant floating-bed technology on polluted river water, and also applied the technology to purify the polluted river water in Miaojia River. Conclusions were summed up in the following:The dominance plant option test was carried out among Oenanthe javanica, Lolium mutliflorum and Allium sativum under low temperature condition. The results showed that the Oenanthe javanica was the dominance floating-bed plant under low temperature condition. Its net removal rate of TN、 NH_3-N、 TP、 COD_ were 51.3%、 65.2%、 55.6%、 57.6%, respectively, and inhibition rate of algae reached 92.3%.
