硅藻土作为吸附材料去除水中氟的研究进展

水中氟化物的含量对人体的健康有重大影响,饮水中最佳的氟含量介于0.5~1.0mg/L之间。归纳了氟污染的来源、危害及含氟废水的处理方法,论述了硅藻土作为吸附材料去除水中氟的作用机理及硅藻土改性研究进展,指出今后应加强硅藻土处理含氟废水的基础研究、硅藻土改性研究及硅藻土水处理技术的工业化研究。

Research Progress of Treatment of Fluoride Containing Wastewater by Diatomite Used as Adsorbent Material

The content of fluoride in water has significant effect on the health of human body.The best fluorine content in drinking water is between 0.5 - 0.5 mg/L.The source and hazard of fluoride pollution and treatment methods of the fluoride-containing were concluded and the basic principles of treatment of fluoride-containing wastewater by diatomite used as the adsorbent material and research progress of diatomite modification were introduced. It was pointed out that basic research of treatment of fluoride wastewater using diatomite, diatomite modification research and the industrialization research of water treatment technology of diatomite should be strengthened in future.
