摘要
以开发经济型处理含氨废水的工艺为目标,拟选用具有较强选择性和吸附性的粉末状活性炭和天然斜发沸石作为吸附材料,以人工配置的含氨废水模拟实际废水,通过烧杯实验,系统地考察粉末状活性炭和活化沸石联合应用对废水中氨氮的去除效果,以及沸石在去除水体中氨氮的技术参数。结果表明:在相同实验条件下,先投放活性炭后投放沸石去处氨氮的效果最好,去除效率可达70%～75%,比先投放沸石后活性炭的效果高出25%左右。
The objective of this work is to develop an economical process to reduce ammonium in wastewater.The active carbon and active zeolite were employed as a specific sorbent,which have relatively strong selective and adsorptive properties to NH_4+-N.Effects of dusty active carbon and active zeolite combined application on absorbing NH_4+-N were investigated by the shaker batch experiments,as well as the technical parameters of zeolite in removing NH_4+-N.The results indicate that the best of adding method for NH_4+-N adsorption was to add dusty active carbon firstly and active zeolite secondly,and the removal efficiency can be up to 70%~75%.
