摘要
该文对组合家庭人工湿地系统处理北方农村生活污水进行了为期10个月的试验研究(包括冬季)。湿地床上部铺设了0.5m的生物质保温层,使在冬季最低气温-15℃的低温下,系统温度仍维持在7℃以上,保证了系统的正常运行。结果表明,化学需氧量(CODcr)、生化需氧量(BOD5)、氨氮(NH3-N)、总磷(TP)、总固体悬浮物(TSS)和浊度的平均去除率分别为93.0%、96.0%、88.4%、87.7%、97.0%和89.6%,出水体积质量平均值分别为36.0、11.8、3.5、0.6、3.8mg/L和浊度9.1NTU,满足国家排放二级标准。组合家庭人工湿地系统是一种适合农村分散式家庭污水处理的新途径。
A ten months continuous study （covering winter period） was conducted on an integrated household constructed wetland system for rural wastewater treatment. With a 0.5 m of biomass thermal insulation layer on the top of the system, the system temperature remained above 7℃ while the lowest climate temperature of-15℃, guaranteeing the ordinary treatment efficiency. The removal rates of COD, BOD5, NH3-N, TP, TSS, and turbidity were 93.0%, 96.0%, 88.4%, 87.7%, 97.0% and 89.6%, respectively. The effluent concentrations were 36.0, 11.8, 3.5, 0.6, 3.8 mg/L and 9.1NTU, respectively. The perfect removal efficiency of integrated household constructed wetland proved its potential application in the rural areas for the distributed wastewater treatment and environment protection.
