- Abstract:
- The paper introduced the operation of initial rainwater and river water treatment before and after the reconstruction of the purification system consisting of pretreatment unit and horizontal subsurface-flow constructed wetland in Loucun Wetland Park, Shenzhen. During the operation of the wetland in 2021, the effluent quality stably met the class Ⅳ limit specified in the Environmental Quality Standard for Surface Water (GB 3838-2002), and the key pollutant indicators such as COD, BOD5, ammonia nitrogen and total phosphorus met the class Ⅲ limit in some periods. In addition, the paper analyzed the technical reasons and application prospects of improving the treatment efficiency of initial rainwater and river water after the reconstruction, discussed the ecological and environmental benefits of Loucun Wetland Park, explored the problems that need to be paid attention to in the management process of the wetland park, and proposed suggestions on the marketization and long-term management mechanism.
