摘　　要：以粉煤灰为原料,在微波场下水热合成人造沸石,可缩短结晶时间。将这种人造沸石应用于污水处理实验,处理城市景观用水,控制水体富营养化的氮、磷指标。氨氮的去除机理主要为离子交换,而磷的去除机理的研究目前尚缺乏相关资料。合成沸石中含磷量较低时,不影响在污水处理中的应用。The synthesis technologies of zeolite with fly ash by hydro - thermal method under the microwave, can shorten crystallization time. This zeolite is used for the test of the wastewater treatment,in order to control nitrogen and phosphoric of water. The cleaning mechanism of ammonia nitrogen is mainly an ion exchange, but the study of phosphorous removal still lacks related date currently. It doesn＇t influence in the application in the wastewater treatment, when the contain amount of phosphoric in the zeolite is lower.
