摘要
沸石是一种天然、无毒无害、无污染的环境友好型材料,采用沸石处理水有许多其它方法无法比拟的优点。利用沸石的吸附与离子交换性质去除污染物具有工艺简单、操作方便、高效快速以及无二次污染等优点而倍受人们关注。首先分析了天然沸石在水处理中的脱氮应用情况,然后针对天然沸石存在的问题,对目前的解决方法进行了分析和研究,最后提出生物再生改性沸石,可较好地解决沸石脱氮在水处理工程中推广的瓶颈问题。
Zeolite is a nontoxic, harmless, pollution-free, environment-friendly and natural material. Due to the good adsorption and ion-exchange capacity of zeolite, it has many advantages over other methods to use zeolite for water treatment, such as simple technology, convenient operation, high efficiency and no pollution. In this paper, the application of natural zeolite to nitrogen removal was analyzed. In addition, present solutions to the deficiency of natural zeolite used in water treatment were discussed, and a better solution for engineering application of zeolite, modified zeolite and bio-regeneration was proposed.
