The test on treating multiple pollution water of Handan has been continuing for a long-term by using the composite constructed wetland system,in which the aquatic plants with stain resistance are selected.The results show that the constructed wetland has a purifying effect perennial,the removal rate of BOD,TN and TP are 25～65%,27-84% and 30-80%,respectly.The removal effect and stability of subsurface flow wetland is better than surface constructed wetland's.The influence factors of removal effect are temperature,plant growth conditions and matrix,and the changing of temperature is the main factor.
