| 摘 要： | 采用改性的安徽繁昌天然斜发沸石，进行有机物对氨氮去除的影响试验。结果表明：沸石能有效地去除大分子的有机物，对小分子有机物的去除效果很差。因此，具有较大相对分子质量的有机物会妨碍沸石去除氨氮。去除大分子有机物能有效地提高氨氮的去除效果。混凝与沸石的组合能有效地去除氨氮和有机物。

| Abstract: | The natural chnoptilolite zeolite of Fanchang County, Anhui Province, was selected and modified for evaluating impact of organics on removal of ammonia-nitrogen by zeolite. The results demonstrated that the zeolite could be effective for removing higher molecular weight (MW) organics but less effective at lower one. Therefore, removal of organics with higher MW could enhance the efficiency of ammonia-nitrogen removal by zeolite, which might otherwise impede the removal. The zeolite coupled with coagulation can remove both ammonia-nitrogen and organics effectively. |

| Keywords: | natural zeolite ammonia-nitrogen organics distribution of molecular weight coagulation |
