含氟工业废水处理及回用工艺分析

Treatment and Recycling Technology of Fluorine-containing Wastewater

为有利于氟物质的回收利用,不仅要考虑含氟废水处理的达标稳定性,还应根据水质情况进行全面分析。通过工艺对比分析,建议采用适用于高氟废水处理的化学沉淀法、电凝聚法、晶种沉淀法与适用于低氟废水处理的吸附法、膜分离法进行联用,或将含氟废水用于化工产品生产的方法,作为含氟废水达标处理和氟物质回收利用的有效途径。

Benifiting the recovery of fluorine material should not only consider the standard stability of the treatment of fluorid wastewater but also should make a comprehensive analysis according to the water quality.Through the analysis of technology comparison,the treatment of high fluoride wastewater by chemical precipitation method,electro-coagulation method,seed precipitation and the treatment of low fluoride wastewater by adsorption method and membrane separation method are advised to be combined or the fluorine-containing wastewater is reused in the chemical production,which can be the effective way to achieve the standard treatment of fluorid wastewater and recycling of the fluorine material.
