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.
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。
2) river course for sewage discharge
排污河道
3) contaminated rivers and ditches
排污河渠
1.
Through imitative experiment research on lead removal of contaminated rivers and ditches by three kinds of media of unsaturated zone,it is found that lead in contaminated rivers and ditches can be removed and depurated by different media, and removal ratio of lead increases with depth Different media have different removal results:medium sand have a higher removal ratio than coarse sand.
通过对 3种不同介质的包气带对排污河渠中铅的去除模拟实验研究发现 ,不同的介质对排污河渠中的铅都具有去除和净化的功能 ,并且随着包气带深度的增加 ,铅的去除率逐渐升高 ;不同的介质对铅的去除效果不同 ,中砂对铅的去除明显优于粗砂 。
