摘要
为了探究Cr6+污染土壤生物还原解毒剂应用的可行性,利用不同浓度的Cr6+污染土壤开展生物还原解毒剂施用研究实验。结果表明:重度铬污染土壤施用生物还原解毒剂240d后,土壤浸出液中Cr6+浓度低于危险废物鉴别标准-浸出毒性鉴别标准所规定的限值;轻度铬污染土壤施用生物还原解毒剂60d后,土壤浸出液中Cr6+的浓度符合中华人民共和国地表水环境质量标准V级标准,说明用微生物法处理Cr6+污染土壤是切实可行的。
Different concentrations of Chromium（Ⅵ） contaminated soil were used to conduct experimental study on biological reduction antidote,the results of the preliminary experimental study showed that,the extraction toxicity was lower than the regulation values of the identification standard for hazardous wastes after applying biological reduction antidote for 240 days;after applying biological reduction antidote for 60 days,the concentration of Chromium（Ⅵ） in extract complied with the national environmental quality standards for surface water V-grade standard.That is to say that treating Chromium contaminated soil by microbial method is feasible.
