生物陶粒柱和粉末活性炭作为淹没式中空纤维膜过滤装置的预处理工艺不仅解决了膜过滤装置氨氮去除不利的弱点 ,避免了亚硝酸盐氮的积累 ,而且在浊度、细菌、有机物等方面极大地降低了膜过滤装置的负荷。生物陶粒柱 -PAC -膜过滤装置系统高锰酸盐指数平均去除率为 76 .97% ,氨氮和亚硝酸盐氮的平均去除率分别达到了 95 .5 0 %和 99.15 % Biological ceramic column and powdered activated carbon filter as submerged hollow fiber membrane pretreatment process not only to solve the disadvantage of ammonia membrane membrane filtration device disadvantage, to avoid the accumulation of nitrite nitrogen, but also in terms of turbidity, bacteria, organic matter, etc. Greatly reducing the membrane filtration device load. The average removal rate of permanganate index in biological ceramsite column-PAC membrane filtration system was 76.97%, and the average removal rates of ammonia nitrogen and nitrite nitrogen reached 95.5% and 99.15% respectively
