| 摘 要： | 系统地研究了天然沸石去除饮用水中低浓度氨的工艺参数，包括沸石的粒径大小、水流流速、初始氨浓度和pH等对处理效果的影响；对再生液中钠离子浓度、pH及其再生液流速对沸石再生的影响进行了研究，结果表明，该种天然沸石不仅能很好地去除水中微量氨离子，而且还能被有效地重复于生；经重复使用和再生18次，其氨交换容量仅降低了4%，因此，该天然沸石用于去除水中微量氨，具有工业应用的潜力。

| Abstract: | Studies the removal of low concentration ammonia from drinking water using the clinoptilolite packed in a column reactor with drinking water containing low concentration ammonia passing through the reactor. To investigate the effects of several operating variables in column operation, such as particle size of clinoptilolite, loading rate, initial ammonia concentration and pH in influent, on the ion exchange capacity systematically, and explores further the effects of sodium ion concentration, pH and flow rate of regenerating solution on the clinoptilolite regeneration, and concludes that clinoptilolite can effectively remove low concentration ammonia from drinking water, and can be regenerated repeatedly and the ion exchange capacities decreased 4 percent for loading and regenerating 18 times. |
