摘　　要：针对人工湿地在北方寒冷地区运行效果不佳、容易堵塞、抗冲击负荷低等问题,河南省某河道在其河滩地采用生物曝气塘+表面流人工湿地+复合垂直潜流人工湿地+稳定塘的异位组合工艺对其水体进行深度处理,设计处理规模12×10^(4)m^(3)/d。2019年实际运行数据表明,在进水水质不稳定的情况下,出水水质依然稳定达到或优于《地表水环境质量标准》(GB 3838—2002)Ⅳ类标准,对COD、NH_(3)-N、TP的平均去除率分别为39.52%、55.53%、35.97%。该技术在原位生态修复用地紧张、水质提标要求较高、水量波动较大等微污染河流治理中具有推广价值。Constructed wetlands are often suffering from poor operation effect, easy blockage and low impact load resistance in the northern cold regions. In terms of these problems, a combined process of biological aeration pond, surface flow constructed wetland, composite vertical flow constructed wetland and stable pond are utilized in a river channel of Henan Province for advanced treatment of its water body, and the designed treatment capacity could reach to 12×10^(4)m^(3)/d. The operation results in 2019 showed that the effluent quality could still reach or surpass the level Ⅳ criteria in Environmental Quality Standards for Surface Water(GB 3838-2002) even under the condition of unstable influent quality, and the average removal percentage of COD, NH_(3)-N and TP were 39.52%, 55.53% and 35.97%, respectively. This technology could provide reference for managing micro-polluted river, especially in the areas short of in-situ ecological restoration lands, with high raising water quality standard and great fluctuation of water quantity.
