| 摘 要： | 通过分析含铬 (Ⅵ )废物堆放场所引起的土壤 /地下水污染特点 ,说明含铬 (Ⅵ )废物污染的潜在与长期危害不容忽视。在污染土壤中进行土著微生物的筛选与初步应用实验 ,其中的土著真菌具有较强的还原能力 ,仅用 2 3d就使铬渣浸出液的六价铬浓度从 115 1.2 /mg·L-1下降到 10 .9/mg·L-1,具有良好的生物解毒作用 ,为含铬 (Ⅵ )废物的处置及污染土壤的修复开辟了一条新途径

Characteristic of Soil/Underground Water of Chromium Waste Stock and Experimental Study on Biological Detoxication of Aboriginal Microbe |
| |
| Abstract: | This paper analyzed the characteristic of soil/underground water of chromium waste stock.It showed that chromium(Ⅵ)waste pollution was potential and permanent.Applied experiments with the microbe which was screened from the polluted soil was done.The result was the reduction ability of aboriginal epiphyte was stronger,the concentration of Cr 6+ of dip water from chromium ejecta was reduced from 1151.2/mg·L -1 to 10.9/mg·L -1 by 23d.The biological detoxication function was a new way to recondition the soil which was polluted by chromium waste. |
