Abstract:
In order to explore the effect of newly restored wetland on advanced purification of coastal water and improvement of water ecological function, the influent and effluent quality of each ecological unit of Yingwuzhou wetland in Shanghai was monitored from August 2017 to April 2019, and the contribution of each block in the wetland to pollutants removal was analyzed. After treated by the Yingwuzhou wetland, the average removal rates of ammonia nitrogen (NH4+-N), nitrite nitrogen (NO2--N) and nitrate nitrogen (NO3--N) were 49.2%,46.3% and 52.9%, respectively, the average removal rates of dissolved inorganic phosphorus (DIP) and total phosphorus (TP) were 53% and 55%, respectively, and the average removal rate of suspended solids (SS) was 59.6%. Synergistic effect of different wetland areas could effectively remove different pollutants and improved the water transparency, which deeply purified the water quality.
