摘　　要：在5种水力负荷条件下,以间歇进水的方式对地下渗滤系统处理灰水的特性进行了研究。结果表明,试验所用灰水及各处理出水的TN、NH4+-N和TP值均优于《城镇污水处理厂污染物排放标准》(GB 18918—2002)的一级A标准,而处理出水的COD值仅达到三级标准;对浊度、COD、NH4+-N和TP的平均去除率随水力负荷的增大呈现高度显著的线性下降趋势,对TN的平均去除率与水力负荷之间没有明显的线性相关关系;当水力负荷为1 m3/(12 m2.4 h)时,对浊度、COD、TN、NH4+-N和TP的平均去除率分别为47.09%、31.88%、22.54%、49.92%和47.06%。研究表明,地下渗滤系统在灰水处理方面具有一定的应用潜力。The treatment of grey water by subsurface infiltration system with 5 different hydraulic loadings was investigated under intermittent feeding. The results showed that the TN, NH4 - N and TP of the tested grey water and each effluent met the class I -A criteria specified in the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant （GB 18918 -2002 ）, but the effluent COD could only reach class m criteria. The average removal efficiencies of turbidity, COD, NH4 - N and TP declined with the increase of hydraulic loading, while the removal efficiency of TN had no significant linear correlation with hydraulic loading. The average removal rates of turbidity, COD, TN, NH4^＋ - N and TP were 47.09%, 31.88%, 22.54%, 49.92% and 47.06% respectively while the hydraulic loading was 1 m^3/ （ 12 m^2. 4 h）. The subsurface infiltration system exhibited potential for the treatment of grey water.
