defluorination meaning in English

除氟作用
去氟
脱氟作用

According to the water supply source used the mining area in bai yun , based on the mechanism of coagulation and flocculation , the feasibility of removing fluoride from water with the method of coagulation and filtration is studied through experiment . and several key parameters which affect defluorination are also analyzed . by using polyaluminum chloride ( pac ) as coagulant , the optimum ranges of the operational parameters are obtained
本文根据白云鄂博矿区饮用水的供水水源，以混凝机理为基础，通过静态和动态实验，对用混凝过滤法除氟的可行性进行了研究，并对影响除氟因素的几个主要参数进行实验分析，得出了用碱式氯化铝作为混凝剂进行实际运行时，参数最佳取值范围。
In addition , the result of comparing the coagulating filtration method with the coagulating sedimentation method shows that the former method is superior to the latter one when other conditions are fined . finally , a primary estimation of operation cost for defluorination using pac as coagulant is made
另外，通过对混凝过滤和混凝沉淀除氟两种方法对比实验研究，表明在其它条件相同的情况下，前者优于后者，从而进一步证明了混凝一直接过滤可代替混凝沉淀法除氟。
