深圳市楼村湿地公园的改建、运行与管理

Reconstruction,Operation and Management of Loucun Wetland Park in Shenzhen

以深圳市楼村湿地公园为例,介绍了由预处理单元和水平潜流人工湿地所组成的水质净化系统改建前后,处理初期雨水及河道水的运行情况。2021年运行期间,出水水质稳定达到《地表水环境质量标准》(GB 3838—2002)Ⅳ类水标准,部分时期COD、BOD5、氨氮、总磷等关键污染物指标可以达到Ⅲ类水标准。同时,分析了改建后系统处理初期雨水及河道水效能提升的技术原因及应用前景,论述了楼村湿地公园所取得的生态环境效益,探讨了管理过程中需要注意的问题,并就市场化、长效的管理机制提出了建议。

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 classⅣlimit 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 classⅢlimit 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.
