摘　　要：根据某流域山区河流自然环境现状特征及北方冬季寒冷的特点,采用"双肾型"布水方案,设计构建生态护岸+生态沟+人工表面流湿地+人工潜流湿地复合型净化系统处理受污染河水。通过恢复湿地植物,协调水与动植物的关系,健全其湿地生态系统,促进湿地自然发育,提高生物多样性。复合型人工湿地明显提高了污染物去除效率,为河流水质稳定达标提供了技术支撑。According to the current situation of the river natural environment in a mountainous area of a river basin and the characteristics of the cold winter in the north, the "two-kidney" water distribution scheme was adopted to design and construct the ecological revetment + ecological ditch + artificial surface flow wetland + artificial subsurface flow wetland complex purification system to deal with the polluted river water. Through restoring wetland plants, coordinating the relationship between water and plants and animals, perfecting their wetland ecosystem, promoting the natural development of wetlands and improving biodiversity,the composite constructed wetland was significantly improved the removal efficiency of pollutants, which provided technical support for the river water quality to reach the standard stably.

关 键 词：山区河流 受污染河水 复合型净化系统 稳定达标
