硝化速率测定和硝化细菌计数考察脱氮效果的应用

Measurement of Nitrifying Rate and Nitrobacteria Count for Application to Investigating the Effects of Denitrification

通过对闵行污水处理厂、某石化厂污水处理厂生物脱氮系统硝化段活性污泥的硝化速率测定和硝化细菌计数,并结合其运行水质数据,分析了两污水处理厂的脱氮效果差异及其原因。结果表明,生物脱氮系统硝化段的硝化速率和硝化细菌数量是判断生物脱氮效果的重要依据。

Through measuring the nitrifying rate and nitrobacteria count of Minhang wastewater treatment plant of Petrochemical Factory at the activated sludge biological denitrification stage, and incorporated water with their water quality data, to analyze the difference of denitrification effects and the reasons between two plants. The result showed that the measurement of nitrifying rate and nitrobacteria count was an important basis for determining the denitrification effects.
