改性沸石用于水的降氟实验研究

Study on the experiment of removing fluorine with modification zeolite from driking water

本文采用伊盟天然沸石作为吸附F-的滤料,用于水的降F-实验研究。实验结果表明:沸石的灼烧温度、沸石的粒度、是否改性对沸石降F-效果有一定影响。而且经测定改性的20-40目无灼烧沸石降F-效果最好。

The paper introduced the removing method of high fluorine driking water with natural zeolite pretreated by Fe(NO3)3 solution. The results have shown that firing temperature, size, modification of the zeolite have different effects on the removing fluorine, and modification zeolite which is 20 - 40mesh and is not fired can remove fluorine effectively from drinking water.
