| 摘 要： | 以某铬渣污染场地上抽提上来的低浓度含铬地下水作为实验研究对象。选用铁屑对含铬废水进行处理。通过静态试验考察了影响六价铬去除率的因素:pH、铁屑用量、反应时间,得到了较好的反应工艺参数。并在静态试验的基础上,用铁屑填充自制的反应柱研究了动态试验的效果。结果表明:六价铬的出水浓度低于0.05 mg/L,达到GB/T 14848-93《地下水质量标准》Ⅲ类排放标准。

| Abstract: | Low concentration chromium-containing groundwater exacted from the slag contaminated site was studied.Iron filings was chosen to treat chromium-containing groundwater.Some influential factors like pH value,the amount of iron filings and reaction time were examined by static test.Technological parameters of the reactions have been obtained.On the basis of static tests,the effect of dynamic wastewater treatment by the self-made reaction column filling iron filings was studied.The results show that the content... |
