天然沸石降氟试验

Removal of F-ions from water by natural zeolite

本文对天然沸石的降氟性能进行了实验探讨。结果表明,天然沸石经酸处理后,具有较好的降氟性能。实验中,我们进行了影响沸石降氟的各种因素的研究,包括:处理酸的浓度,时间;沸石的粒度和焙烧温度;沸石作用时间;剂量;氟离子浓度等。并且对沸石降氟能力的再生进行了研究。还通过沸石降高氟水的实地研究,说明用天然沸石降氟的可行性。

The removal of F-ions in water by natural zeolite was investigated.Factorswhich affect the asorption capacities of F^- ions in water by natural zeoliteincluding the acid concentration of the treated natural zeolite and time of treat-ment of acid and the concentration of F^- ions;quantity of absorbent,ect,were systematically studied in this paper.It is concluded that the natural zeolite treated by acid could be used as an abs-orbent of F^- ions in water and F^- ions absorbed by natural zeolite could be re-moved by consecutive regeneration of zeolite with acid.
