| 摘 要： | 传统的抽出处理技术治理铬污染地下水时,耗时长、效率低、投资与成本高,限制了其广泛应用,近年来兴起的PRB技术很好地解决了这一问题。PRB技术的关键在于反应介质的研究,活性炭、沸石、铁屑等具有较好的除铬性能,但选择性差、易堵塞,混合反应介质可以克服其缺点。同时,对反应介质的研究大多处于实验室阶段,应加强其工程应用研究。

| Abstract: | As a traditional method of treating chromium contaminated groundwater,pump-and-treat technology is time consuming、low efficiency、high investment and cost,which limits the wide application.However,the emerging technology of PRB developed in recent years solves the above problems.The key to PRB technology is research of reaction medium.Activated carbon,zeolite,scrap iron and so on all have a good removal capacity of chromium,but the selectivity is poor and the medium can be easily jammed.Mixed reaction medium can overcome the shortcomings mentioned above,and the study of medium is still being in the laboratorial stage,engineering application research should be strengthened. |
