我国沸石去除水中氨氮的现状研究

Status Quo of Removing Ammonia Nitrogen from Water by Zeolite in China

沸石是一种天然、有效、价廉的环境友好型材料,其对氨氮具有很强的选择吸附性。本文就国内在沸石去除水中氨氮的机理、影响因素、沸石的改性及沸石研究的发展等方面进行广泛探讨。阐述了国内沸石去除水中氨氮的应用现状和进展,并指出沸石的推广要依赖于沸石改性和与其他工艺的联用技术开发。

Zeolite is a natural,effective and cheap material to absorb ammonia nitrogen specially.In this paper,the respects including mechanism of removing ammonium from water by zeolite,influencing factors,the modification of natural zeolite and the researches related were discussed widely.The status quo of applications of zeolite to remove ammonia nitrogen in China was introduced.It pointed out that extension application of zeolite depended on the modification of zeolite and the combination of zeolite with other processes.
