中文摘要:

在滇池流域构建氧化塘-浮石床湿地复合系统对暖季与寒季的城市低污染河水开展了净化效能研究。结果表明:该系统可通过小幅调节流量来有效净化暖季与寒季低污染河水。塘与湿地的水力负荷分别为0.22、0.37 m³/(m²·　d)时系统对暖季低污染河水具有较高的处理效率,各污染物的平均去除率分别为CODCr 75%、TP 93%、TN 64%、NH₄[KG-*3/5]⁺-N 87%。塘与湿地的水力负荷分别为0.17、0.29 m³/(m²·　d)时系统对寒季低污染河水具有较优的处理效果:各污染物的平均去除率分别为CODCr 72%、TP 89%、TN 53%、NH₄[KG-*3/5]⁺-N 73%。系统出水均符合GB18918-2002的一级A排放标准。系统在暖季对低污染河水中污染物的去除速率明显高于寒季。

英文摘要:

An study on treatment of slightly polluted river water was carried out using the combined system of oxidation pond with constructed wetland using pumice as substrate in Kunming. The results shown that the system can purify polluted river water both in warm and cold seasons efficiently by regulating flow to a small extent. When the hydraulic loading rates of pond and wetland were held at 0.22 and 0.37 m³/(m²·　d) respectively,adequate treatment could be got by the whole combined system and the mean removal efficiencies of CODCr, TP, TN and NH₄[KG-*4/5]⁺-N in the system for warm season were 75%, 93%, 64%, 87% respectively, and for cold season were CODCr 72%, TP 89%, TN 53%, NH₄[KG-*4/5]⁺-N 73% at the appropriate hydraulic loading rates of pond and wetland held at 0.17 and 0.29 m³/(m²·　d) respectively. The treated water met the standard A of grade I discharge standard of pollutants for municipal waste water treatment plant, and can be used as urban general reuse water. Contaminant removal rate in the combined system in warm season was apparently higher than that in bcold season.
