Method for treating high-concentration fluorine-containing wastewater by using modified aluminate cement and fluorine removal agent for high-concentration fluorine-containing wastewater
The invention discloses a method for treating high-concentration fluorine-containing wastewater by using modified aluminate cement and a fluorine removal agent for the high-concentration fluorine-containing wastewater, and belongs to the technical field of environmental protection water treatment. The method for treating the high-concentration fluorine-containing wastewater by using the modified aluminate cement comprises the following steps: putting fluorine removal agent pellets prepared from the aluminate cement into the fluorine-containing wastewater for primary fluorine removal; adjusting the pH value of the effluent subjected to the primary defluorination treatment, adding a flocculating agent to promote precipitation, and carrying out secondary defluorination; wherein the pH value of the effluent after the primary defluorination treatment is adjusted to 7-9. The fluoride-containing wastewater is treated by adopting the hydrated aluminate cement pellet fluoride removal agent, the specific treatment process is optimized, especially through two-stage fluoride removal treatment, deep fluoride removal of the high-concentration fluoride-containing wastewater can be realized, the used fluoride removal agent has the advantages of high fluoride removal rate, high fluoride removal speed, high strength, large specific surface area, easiness in separation and the like, and the fluoride removal agent has a good application prospect. The production process is simple, raw materials are easy to obtain, and the cost is low.
本发明公开了一种改性铝酸盐水泥处理高浓度含氟废水的方法及高浓度含氟废水用除氟剂，属于环境保护水处理技术领域。本发明的利用改性铝酸盐水泥处理高浓度含氟废水的方法，包含：将采用铝酸盐水泥制成的除氟剂球粒投入含氟废水中进行一级除氟；一级除氟处理后的出水pH值经调节后，投加絮凝剂促进沉淀，进行二级除氟；其中，调节一级除氟处理后的出水pH值至7～9。本发明采用水化铝酸盐水泥球粒除氟剂对含氟废水进行处理，并对其具体处理工艺进行优化，尤其是经两级除氟处理，可以实现高浓度含氟废水的深度除氟，所用除氟剂具有除氟率高、除氟速率快、强度高、比表面积大、易分离等优点，且其生产过程简单、原料易得、成本低。
