用于氨氮处理的沸石的合成条件研究

Research on synthesis conditions of zeolite used for treatment of ammonia-nitrogen wastewater

采用水热合成法在不同条件下合成不同的沸石,分别处理氨氮模拟废水(1000 mg/L),筛选出氨氮处理效果最好的沸石.证明在合成条件为反应时间8 h,温度100℃,钠硅比为3,水钠比120下合成的沸石处理氨氮效果最好.

Adopted hydrotherrnal synthesis method to synthetise different kinds of zeolite in different conditions, treated analogue ammonia-nitrogen wastewater （1000 mg/L） with each zeolite. Proved the zeolite synthesized in the condition of react 8 h, react temperature at 100 °C, the ratio of sodium and silicon is 3, the ratio of water and sodium is 120 achieve the best result in process of ammonia-nitrogen wastewater.
