| 摘 要： | 室内试验选用3种天然砂土作为渗透介质,以生活污水模拟排污河水,发现中砂(60%～90%)对COD的去除作用优于粗砂(77%),但如果河水的COD浓度比较高时,COD也能有一部分穿过渗透介质进入地下水中,尤其是粗砂,COD的去除机理主要是厌氧生物降解。通过对凉水河及其邻近浅层地下水COD浓度的对比,以及凉水河野外抽水,发现凉水河对地下水存在着COD污染,并且离河越近河水对地下水的影响越大。

| Abstract: | In the lab-scale experiment three kinds of natural sand were chosen as infiltration medium, and polluted rivers were simulated by domestic sewage, it was found that medium sand (60%~90%)had a higher removal ratio of COD than coarse sand(77%), but some COD can go into ground water through infiltration medium (particularly coarse sand) when the concentration of COD in river was high. The main removal mechanism of COD is anaerobic biological degradation.By contrast of the concentration of COD between Liangshui River and adjacent groundwater, and pumping in Liangshui River, it was found that Liangshui River had influence on groundwater, and more influence occurred when the distance of river was closer. |
