摘　　要：以昆明市新运粮河工程示范区的间歇进水、连续出水氧化塘/湿地复合系统为研究对象,考察了其对城市旱期低污染河水与雨期重污染河水的净化效果。结果表明:该复合系统可以有效处理旱期低污染河水和雨期重污染河水,实现削减污染和美化景观的双重功能。在旱期对低污染河水中SS、COD、TP、TN、NH_4^+-N的去除率分别为(89.2±0.4)%、(73.8±5.1)%、(78.9±4.5)%、(64.4±3.9)%、(75.1±7.5)%,在雨期对重污染河水中各污染物的去除率分别为(93.6±0.5)%、(74.7±0.8)%、(81.0±1.0)%、(66.6±5.0)%、(81.4±0.4)%。系统出水水质均达到《城镇污水处理厂污染物排放标准》(GB 18918—2002)的一级A标准,可作为城镇景观用水和一般回用水。Taking the combined system of oxidation pond and constructed wetland with intermittent inflow and continuous outflow in the demonstration zone of Xinyunliang River project in Kunming as research object, its purification efficiency of low polluted river water in dry season and high polluted river water in rainy season was investigated. The results show that the combined treatment system can treat polluted river water efficiently and realize the functions of reducing pollution and beautifying the environment. The removal rates of SS, COD, TP, TN and NH4^＋ - N from low polluted river water in dry season are （89.2±0.4）%, （73.8±5.1）%, （78.9±4.5）%, （64.4±3.9）% and （75.1±7.5）% respectively, and those from high polluted river water in rainy season are （93.6 _＋ 0.5 ）% , （74.7 ± 0.8 ） % , （ 81.0± 1.0） % , （66.6 ± 5.0） % and （ 81.4 ± 0.4） % respectively. The treated water meets the first level A criteria specified in the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant （GB 18918 -2002） , and can be used as urban landscape water and other general reuse wa-ter.
