一体式好氧膜生物反应器的氮转化试验研究

Research on Nitrogen Transformation of IAMBR

一体式好氧膜生物反应器(Integrated aerobic membrane bio-reactor,简称IAMBR)内提供了世代时间较长的硝化菌生长环境,从而使得硝化作用增强。从氨氮浓度与亚硝酸氮浓度比值随天数变化,氨氮浓度与硝酸氮浓度比值随天数变化,亚硝酸氮浓度与硝酸氮浓度比值随天数变化角度分析了IAMBR内氮的转化情况,得出氨氮去除主要依靠膜生物反应器内的好氧污泥,并且IAMBR可用于去除氨氮的结论。

IAMBR provides growing environment for the long generation time nitrobacteria,so the nitrification is improved.The nitrogen transformation of LAMBR is analyzed based on the proportion of ammonia nitrogen and nitrate concentration with days changing,that of ammonia nitrogen and nitrite concentration,and nitrate and nitrite concentration,finding out that the removal of ammonia nitrogen mainly depends on the aerobic sludge in the IAMBR and IAMBR can be used in the practice of ammonia nitrogen removal.
