| 摘 要： | 在静态条件下,利用生物矿化针铁矿对含铬模拟废水进行吸附实验研究.结果表明,生物矿化针铁矿对质量浓度在5 mg/L以下的含Cr2O72-,Cr3+模拟废水均具有较好的去除效果,平均去除率达94%,出水达到"污水综合排放标准"(GB 8978-1996);其吸附符合Langmuir与Freundlich模型.

| Abstract: | The sorption experimental study on chromium-containing wastewater treatment with biomineralized goethite(B.G.)under static conditions has been performed.It is shown that the B.G. has high efficiency for the removal of Cr\-2O_7~(2-) and Cr~(3+),the average removing ratio can be as high as 94% and so the effluent accords with the first level criterion of discharge in terms of GB8978-1996.The sorption behavior of B.G. for Cr\-2O_7~(2-) and Cr~(3+) obeys both Langmuir Model and Freundlich Model. |
