| 摘 要： | 比较了在不同改性条件下沸石对氨氮的去除效果,结果表明:NaCl改性效果明显,6%盐溶液浓度改性沸石氨氮去除率可达95.3%;酸浸改性沸石吸附性能明显优于碱浸改性沸石;在2h的浸泡时间下,酸溶液浓度升高,改性沸石的氨氮吸附效果降低.

| Abstract: | The effect of ammonia-nitrogen removal with zeolite under different modified conditions is compared in the paper.The results showed that zeolite modified by NaCl had better adsorbability for NH4 -N,when the concentration of NaCl was 6%,NH4 -N removal rate could reach 95.3%,Higher removal efficiency was obtained by acid-modified zeolite than by base-modified zeolite;based on 2h soaking time in the HCl solution,higher concentration of acid could reduce the adsorption efficiency of the acid-modified zeolite to ammonia-nitrogen. |

| Keywords: | modified zeolite absorption ammonia-nitrogen |
