| 摘 要： | 为了探索寻找到一种价格低廉、效果明显的降低水体氨氮和磷含量的方法,对具有资源丰富、价格便宜的膨润土灰进行了改性及吸附氨氮和磷的静态试验研究,结果表明：对膨润土进行酸、碱、盐和热改性后氨氮的吸附效果有所不同,顺序依次为：热〉碱〉盐〉酸;对膨润土进行酸、碱、盐和热改性后对磷的吸附效果也不同,顺序为：盐〉热〉酸〉碱。技术经济比较,热改性膨润土对氨氮的吸附容量大,而盐改性膨润土对磷的吸附容量大,在两种情况下膨润土是较理想的吸附剂。

| Abstract: | In order to find a cheap and effective ammonia nitrogen and phosphorus removal method,bentonite was modified and modified bentonite was used to remove ammonia nitrogen and phosphorus.The results show that modifications of bentonite by acid,alkali,salt and heat,separately have different effect on adsorption of ammonia nitrogen,the order as follows: heat> alkali> salt> acid;For adsorption of phosphorus,the order as follows: salt >heat > acid > alkali.Through technical and economic comparison,the bentonite mod... |
