粉状沸石吸附及解吸氨氮影响研究

在微污染水中,研究了粉状沸石吸附氨氮的影响因素及曝气对沸石解析的效果.结果表明,在15 min内,沸石对氨氮去除率达到66%,沸石对低浓度氨氮的平均去除率为74%.在不同阳离子共存下,K 使氨氮去除率能降低56%;水中各阳离子共存时沸石对氨氮去除率却下降了36%,初始氨氮浓度越低,阳离子对沸石吸附氨氮抑制作用越明显.纯曝气对沸石解析氨氮效果不显著.

Effect study of powdered zeolite absorbs and resolves ammonium and nitrogen

The paper studies the influence factors which powdered zeolite absorb ammonium nitrogen in less contaminated water,also studies the effect of aeration on the resolve of zeolite,The evidence show that the removal rate reach 66% in 15 minutes,zeolite can remove 74% ammonium nitrogen in a low concentration.Kalium ion may decrease the removal rate of ammonium nitrogen to 56% in different!positive ion coexist condition.The removal rate may fall 36% because of the effect of the positive ion interference.More lower concentration of initial ammonium nitrogen,more obvious effect which restrain zeolite absorbing ammonium nitrogen will occur,pure aeration hardly change the rate.
