摘要
对改性沸石去除氨氮的条件及机理进行了实验探讨。结果表明 ,沸石经过活化剂处理后具有降低水中氨氮的作用。影响沸石去除氨氮的主要因素包括沸石与含氨氮溶液作用时间、沸石用量、溶液中氨氮浓度、沸石的粒度和溶液的温度等 ,探讨了沸石去除氨氮的机理 ,初步认为主要是由于离子交换作用和吸附作用共同完成的。
The condition and mechanism of removing ammonium ions from water by activated zeolite have been investigated in this paper. Some major elements that affecting the treating process such as treating time and temperature, particle and amount of zeolite are studied.The experimental results show that activated zeolite posse an ability of removing NH + 4 due to the ion exchange and adsorption.
