摘要
为了解决富营养化水体中氮磷污染问题,以阜新闹德海水库水源水为研究对象,采用烧杯静态试验,进行了沸石不同改性对富营养化水体氮磷同步去除试验研究.试验结果表明,先1 mol/L氯化镁盐改性再在400℃热改性后的复合改性沸石对氨氮和总磷吸附效果最佳,最佳吸附条件为100mL水样沸石投加量6g,沸石粒径0.15～0.55 mm,吸附时间240 min,pH值7.0～8.0,对氨氮和磷去除率可达89.6％和81.1％.
In order to solve nitrogen and phosphorus pollution problem of the eutrophic Water, taking the Naodehai reservoir source water as a research object, experiments on simultaneous nitrogen and phosphorus removal of the eutrophic water for modified zeolite were conducted by static beaker test. The result shows that when the zeolite was first modified by magnesium chloride （1 mol/L） and then by thermal （400 ℃）, it has the best ammonia nitrogen and total phosphorus adsorption effect in this study. The optimum adsorption conditions were 6 g of zeolite, 0.15-0.55 mm mesh of zeolite particle size and 240 min of adsorption time at pH 7.0 -8.0 for 100 mL of the eutrophic water in question. The removal rates for ammonia nitrogen and total phosphorus can reach 89.6% and 81.1% respectively.
