摘要
通过中试考察了应用可渗透反应墙(PRB)技术修复受污染河水水质的可行性。结果表明:以铁屑、焦炭和沸石为介质的PRB系统对COD、TN、NO3--N、NH4+-N和TP都有较好的去除效果,平均去除率分别为59.36%、62.16%、76.62%、26.85%、82.04%。铁屑的内电解及净化材料的吸附是PRB系统去除污染物的主要机制。
The feasibility of applying permeable reactive barrier （PRB） to remedy polluted fiver water was investigated by pilot test. The results show that the PRB system using scrap iron, coke and zeolite as reactive media has high removal rates of COD, TN, NO3^- - N, NH4^＋ - N and TP, being 59.36%, 62.16% ,76.62%, 26.85% and 82.04% respectively. The internal electrolysis and the adsorption by purifying material are the main mechanisms of pollutant removal in the permeable reactive barrier.
