| 摘 要： | 以2,4-二氯苯酚污染的地下水为研究对象,分别用零价铁屑、天然沸石及其组合作为反应介质,设计了6种地下可渗透反应器(PRB),进行实验室净化模拟研究.结果表明:单独采用零价铁屑、沸石为反应介质时,2,4-二氯苯酚的去除率分别为26%和40%;铁屑与沸石联合作为反应介质时,去除率可提高20%～30%.在地下含水层应用零价铁 沸石的组合填充去除有机污染物时,应沿水流方向依次先填入零价铁,再填入沸石方可达到最佳去除率.

| Abstract: | To remediate 2-4 DCP polluted groundwater, the different reaction media in-situ technologies are studied in laboratory including individually using zero-valent iron, natural zeolite and their combinations. A total of 6 kinds of PRB were designed in the study. The results proved that the removal efficiency of 2,4- DCP could only reach 26% and 40%,respectively if individually by using zero valent iron and natural zeolite. When zero iron was combined with zeolite,the removal rates could be increased by 20%-30%. For the optimal installation to obtain the highest removal efficiency, zero iron might be filled into aquifer at first followed by zeolite along groundwater flow direction. |
