摘要：本文旨在研究在一定曝气时间条件下，序批式反应器和膜生物反应器中化学需氧量与氮的比值（COD/N）和pH值对硝化~反硝化作用去除营养物质的效果。本文分别对COD/N值分别为2，4和6时的情况进行了比较，结果显示，在COD/N为6时，NH₄⁺，NO₃^－和NO₂^－的去除率最高，分别为92.31%，80.69%和93.63%。该比值对于顺利脱氮来说十分重要。当pH值为分别5.5，7.6和9时，NH₄⁺，NO₃^－和NO₂^－的去除效率有巨大差异，当pH值为7.6时，其去除效果最好，此时，NH₄⁺，NO₃^－和NO₂^－的去除率分别为92.31%，84.51%和93.63%。这说明pH值在高于7.6时，营养物的去除率可以维持在90%以上。

Abstract: In this study, the effect of chemical oxygen demand/nitrogen (COD/N) and pH on nitrification-dentrification was investigated by operating a sequencing batch reactor with the use of aeration duration control, coupled with a membrane bioreactor (MBR) system to improve the efficiency of nutrient removal. Among the COD/N ratios of 2, 4 and 6, the removal efficiencies of, and in permeate, were the highest at 92.31, 80.69 and 93.63% respectively, at the COD/N ratio of 6. This ratio is an important factor to be considered for successful nitrogen removal. For pH values of 5.5, 7.6 and 9 there was a great difference in the removal of, and with pH 7.6 were the highest at 92.31, 84.51 and 93.63%, respectively. This implies that a pH above 7.6 should be maintained for a nutrient removal efficiency of approximately 90%.
