某铝厂氟污染土壤修复中试试验研究

Pilot experiment of Remediation of fluorine contaminated soil in an aluminum plant

以典型铝厂氟污土壤为研究对象,选取3个具有代表性的污染区域,试验通过不同药剂配比及投加量下F的稳定化效果。结果表明:对于较高浓度污染,各种药剂均能使F水浸出浓度满足标准要求,但方案B对pH的控制较方案A好。实际工程中需要根据场地类的污染情况,分类治理,确定最终修复方案。

Taking the fluorine polluted soil of a typical aluminum plant as the research object,thre representative polluted areas were selected to test the stabilization effect of F under different dosage and dosage of different dosage.The results show that for high concentration pollution,all kinds of agents can make F water leaching concentration meet the standard requirements,but the pH control of plan B is better than that of plan A.In the actual project,it is necessary to classify treatment and determine the final restoration plan according to the pollution situation of the site.
