中文摘要：

为考察生物生态组合技术对农村生活灰水的处理效果，构建了新型厌氧反应器＋垂直流生态滤池组合系统，分析了其对COD、TN、NH，-N、TP的去除效果。结果表明，在进水COD、TN、NH3-N、TP平均浓度分别为426、10．5、7．1、1．3mg／L的情况下，系统对COD、TN、NH3-N、TP的去除率分别为（85．91±1．96）％、（39．34±4．38）％、（69．94±0．72）％、（83．21±3．31）％。在春季末、夏秋季，系统出水COD浓度能达到《城镇污水处理厂污染物排放标准》（GB18918-2002）的一级B排放标准；系统出水TP浓度全年达到一级A排放标准；系统对TN的去除效果不明显，但仍有较好的削减作用；出水NH3-N浓度全年达到一级A排放标准。该研究为厌氧反应器与生态滤池的设计与应用提供了技术参考。

英文摘要：

To investigate the treatment efficiency of rural grey wastewater by the combination of bi- ological and ecological technologies, a new combined system of anaerobic reactor and vertical eco-filter was built, and the removal efficieneies of COD, TN, NH3 - N and TP were analyzed. The results showed that the removal rates of COD, TN, NH3 -N and TP were （85.91 ±1.96）%, （39.34±4.38）%, （69.94 ±0.72 ） % and （ 83.21 ± 3.31 ） % respectively when the average influent concentrations of COD, TN, NH3 - N and TP were 426 mg/L, 10.5 rag/L, 7.1 mg/L and 1.3 mg/L respectively. At the end of spring and in summer and autumn, the effluent concentration of COD could meet the first level B criteria specified in the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant （GB 18918 -2002）. The effluent concentration of TP could meet the first level A criteria. The removal effi- ciency of TN was not very significant but with certain degree of reduction. The effluent concentration of NH3 -N could meet the first level A criteria. This study can provide technique reference for the design and application of anaerobic reactor and eco-fiher.
