Application example of advanced treatment of urban sewage plant tail water in constructed wetland
This paper tracked and monitored the water quality data of the constructed wetland(CW)for three years,and analyzed its ecological service value.The average removal efficiency of the constructed wetland for ammonia nitrogen,total nitrogen,total phosphorus,suspended solids and COD was 86.12%,16.07%,51.23%,91.23%,and 37.6%respectively.Concurrently,it can bring recharge and utilization of reclaimed water,and maintain biodiversity.The ecological service benefit of the CW can reach 0.78 yuan/m2 in water purification,cultural function,and habitat provision.
