【摘要】 天然沸石及改性沸石对氨氮有很强的选择性吸附能力。介绍了沸石去除废水中氨氮的应用研究,包括在O/A生物处理系统、二级氧化塘处理系统、土地处理系统、湿地系统和堆肥系统等中的应用。分析了氨氮在沸石上发生吸附和离子交换的主要影响因素和规律。为开拓沸石在废水处理中的应用提供科学与技术基础。更多还原

【Abstract】 Natural and modified zeolite have strong selective adsorption ability to ammonia nitrogen in the wastewater. Applications of zeolites to remove ammonia nitrogen from wastewater in O/A biological treatment, two-stage oxidation pond system, land treatment, wetland system and composting system etc., were summarized. Influence factors and rules for adsorption and ion-exchange of ammonia nitrogen by zeolite were analyzed. This provides the scientific and technical basis for the development of zeolite application in wastewater treatment.更多还原
