| 摘 要： | 研究改性微孔沸石球吸附柱去除模拟废水中低浓度氨氮的效果及影响因素。结果表明．沸石球粒径大小、水流流速、初始氨浓度和pH等因素对氨氮交换容量有较大影响，改性微孔沸石球再生能力很强，经过10个周期的重复使用和再生，其氨氮交换容量仅降低了3．4％．在实际应用中有很好的适用性。

| Abstract: | The treatment effect of modified porous zeolite pellet of low concentration NH~+_4-N in column reactor was studied to investigate the influences of such factors as pellet size,flow rate,initial ammonia concentration and pH in influent.It was shown that modified porous zeolite pellet have good removal capacity of low concentration NH~+_4-N in a column reactor and have high regeneration effciency.After having been regenerated for 10 times,the exchange capacity of NH~+_4-N decreased only 3.4%. |
