| 摘 要： | 生物脱氮是废水氮素污染控制的有效技术.本文剖析了pH对生物硝化的影响以及与碱度的关系,认为pH不仅影响硝化细菌的生长和代谢,也影响硝化基质和产物的有效性和毒性,可制约生物硝化反应器的效能.生物硝化系统的碱度主要由碳酸盐类组成.因为碳酸盐系统在pH 6.5～8.5时缓冲强度较弱,硝化过程中极易发生pH大幅度波动,操作中应予以高度关注.

| Abstract: | Nitrification is an effective technology to control nitrogen pollution from wastewater.The effect of pH on nitrification and the relationship between pH and alkalinity were analyzed.It was shown that pH exerted not only a large influence on the growth and metabolism of nitrifying bacteria but also the availability and toxicity of substrates and products.To a great degree,pH restricted the performance of nitrification reactor.The alkalinity of the nitrification system was mainly contributed by carbonates present.Because of the small buffering capacity of carbonates at pH 6.5-8.5,during the nitrification process the pH to being under control tended to fluctuate markedly and measures should be taken in advance. |
