复合水处理填料的研究
填料在水处理中有着广泛的应用,无论是好氧、兼氧还是厌氧过程中,填料都发挥着重要的作用。填料大致可分为固定式、悬挂式、分散型和新型生物填料等类型,每种填料都有其自身的优缺点,因此任何一种填料对废水的处理效果都有其一定的缺陷。蛭石和沸石都具有优异的吸附、离子交换性能,在水处理中有着广泛的应用。两者对污染物质的去除途径相同,对污水中氨氮和总磷的吸附条件有着不少相同之处,如PH值、温度及污染物浓度,但两者在处理效果上各有各的优点。本文主要采用把蛭石和沸石组合成复合型填料的方法,研究蛭石和沸石在不同配比下对氨氮和总磷的去除效果。综合利用两者的优点,提高对氨氮和总磷的去除效率,由实验结论得出复合型填料的最佳配比。为今后利用组合填料治理富营养化水体提供实验基础。

Fill the study of water treatment
Fill in water treatment has a wide range of applications, both aerobic and anaerobic or oxygen and the process of packing has played an important role. Packing can be broadly classified into fixed, hanging, scattered, and new types of packing, and so on, fill each has its own advantages and disadvantages, so any filler on the treatment of waste water has certain defects. Vermiculite and zeolite have excellent adsorption, ion-exchange performance, in water treatment has a wide range of applications. Both the removal of contaminated materials the same way, the sewage in the absorption of ammonia and phosphorus conditions have many similarities, such as PH value, temperature and the concentration of pollutants, but the two in dealing with the effects on their own Advantages. This article used the combination of vermiculite and zeolite into the compound packing method, vermiculite and zeolite in different proportions of the ammonia nitrogen and ph
