摘　　要：采用石灰沉淀和聚合氯化铝(PAC)混凝沉淀相结合的方法去除矿井废水中的硫酸根离子和氟离子,对去除机理及影响因数进行了研究。结果表明,出水中硫酸根和氟的质量浓度可分别控制在30 mg·L^(-1),0．3 mg·L^(-1)以下。The paper sums up the methods for removing F^- and SO4^2- from mine water, Removing F^- and SO4^2- from mine wastewater by the two methods of Lime-sedimentation and PAC coagulation sedimentation is discussed. The mechanism and its influencing factors are studied. The results show that, the content of SO4^2- can lower to below 30 mg·L^-1; the content of F^- can lower to below 0.3 mg·L^-1.
