Abstract：Pilot scale constructed wetlands were built in the estuarine wetland of Huishan Channel in Shenyang City for the treatment of food processing water.The purification of chemical oxygen demand (COD),ammonia nitrogen (NH3-N),total nitrogen(TN) and total phosphorus(TP) was studied,and results indicated that the removal efficiency of COD,NH3-N,TN and TP attained 39.69％,51.23％,35.80％,48.80％ and 45.56％,80.96％,57.30％,80.24％ respectively as to VSF and HVC for treated eutrophic water.Integrated constructed wetland has appropriate dissolved oxygen and temperature environment for microbial survival,and the decomposition and absorption processes of organic matter,nitrogen and phosphorus are complete.However,it is needed to control the pollutant's concentration of inflow in the integrated constructed wetland since the wastewater with high concentration pollutants would has negative effects on wetland plants growth and microbial environment.
