摘要:
为实现银川市第六污水处理厂出水深度处理后回用作为城市生态补水、市政杂用水等，紧邻阅海风景区东岸新建阅海东潜流湿地。项目占地约8.5 hm2，处理规模2.1×104 m3/d，设计进水水质为《城镇污水处理厂污染物排放标准》（GB 18918—2002）一级A标准，设计出水水质执行《地表水环境质量标准》（GB 3838—2002）Ⅳ类标准（TN除外）。潜流湿地采用水平流形式，总有效停留时间约1.36 d，共设计单元格100个，选用砾石+天然火山岩填料，以增强工艺脱氮除磷功能。项目选址场地呈狭长型分布，为保证布水均匀，预处理池至布水渠采取管道多点进水，东侧组、西侧组的布水渠分别设置5个进水点，每个进水点辅以阀门、流量计调节流量，布水效果良好，可为类似项目提供参考。
Abstract:
A new Yuehai east subsurface flow wetland was constructed adjacent to the eastern bank of the Yuehai scenic area to facilitate the reuse of effluent from No.6 sewage treatment plant of Yinchuan City as urban ecological water replenishment and municipal non-potable water after advanced treatment. The project spans an area of approximately 8.5 hm2 and has a treatment capacity of 2.1×104 m3/d. The designed influent quality conforms to the first level A limit specified in Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), while the designed effluent quality meets the class Ⅳ limit specified in Environmental Quality Standards for Surface Water (GB 3838-2002), excluding TN. The subsurface flow wetland system operates under a horizontal flow configuration, providing a total effective hydraulic retention time of approximately 1.36 days. The system consists of 100 modular cells, utilizing gravel and natural volcanic rock as filter media to enhance the nitrogen and phosphorus removal efficiency of the treatment process. The project site exhibits a narrow and elongated configuration. A uniform water distribution system was designed to ensure the effective operation of the subsurface flow wetland. From the pretreatment tank to the distribution channels, water was introduced at multiple inlet points via pipelines. Specifically, five inlet points were established for the distribution channels in the east and west groups, respectively. Each inlet point was equipped with valves and flow meters to precisely regulate the flow rate. The system demonstrates excellent water distribution performance and can serve as a reference for similar projects.
