碱度对污泥硝化活性的影响研究

Study on the Effect of Alkalinity on Sludge Nitrification Activity

本研究主要考察了碱度对污泥硝化活性的影响。研究结果显示,随着碱度的提高,污泥的最大硝化速率发生不同程度的降低。当碱度达到5000mg/L时,污泥发生解体;以上结果表明,随着碱度的提高,污泥的硝化活性逐渐下降,且在某一特定的碱度条件下,污泥将彻底丧失硝化活性。

This study mainly investigated the effect of alkalinity on the nitrification activity of sludge.The research results show that with the increase of alkalinity,the maximum nitrification rate of sludge decreases to varying degrees.When the alkalinity reaches 5000 mg/L,the sludge disintegrates;the above results show that as the alkalinity increases,the nitrification activity of the sludge gradually decreases,and under a certain alkalinity condition,the sludge will be completely lost Nitrification activity.
