摘要:
为构建“从源头到龙头”的饮用水安全保障体系，在平原河网原水进入自来水厂前，构建水源生态湿地进行前处理。然而，运行多年后，水源生态湿地出现了植物根孔堵塞、局部短流、设施设备老旧及出水水质不稳定等问题。为此，从混凝沉淀预处理、水平潜流根孔湿地改造、未改造根孔湿地修复、水生态修复、设施设备更新及智慧湿地系统构建等方面，对水源生态湿地进行原位提标改造。试运行期间，湿地对原水中浊度、CODMn、BOD5、氨氮（NH3-N）及总磷（TP）的去除率分别达到68.3%、29.8%、40.1%、75.8%和65.2%，出水水质由改造前的《地表水环境质量标准》（GB 3838—2002）中Ⅲ类标准提升至Ⅱ类标准，达标率为98.6%。湿地建设及提标改造投资约1 540.3 元/m3，可变成本约0.073元/m3。实践证明，水源生态湿地是平原河网区自来水厂地表原水前置净化处理的有效技术手段。
Abstract:
To establish a drinking water security guarantee system from source to tap, a source-water ecological wetland was constructed to pretreat raw water from the plain river network before it entered the waterworks. After several years of operation, however, the wetland encountered some operational problems, including plant root-pore clogging, localized hydraulic short-circuiting, aging facilities and equipment, and unstable effluent quality. The source-water ecological wetland was upgraded and renovated in situ through raw water coagulation-sedimentation pretreatment, retrofitting of the horizontal subsurface-flow root-pore wetland, restoration of the unmodified root-pore wetland, aquatic ecological restoration, renewal of facilities and equipment, and construction of a smart wetland management system. During the trial operation, the removal efficiencies of the wetland for turbidity, CODMn, BOD5, NH3-N and TP reached 68.3%, 29.8%, 40.1%, 75.8% and 65.2%, respectively. The effluent quality improved from class Ⅲ to class Ⅱ in the Environmental Quality Standards for Surface Water (GB 3838-2002), with a compliance rate of 98.6%. The investment in wetland construction and upgrading was approximately 1 540.3 CNY/m3, while the variable treatment cost was approximately 0.073 CNY/m3. The results indicate that source-water ecological wetland can serve as an effective technology for the pretreatment of surface raw water at waterworks in plain river network areas.
