摘要
通过检测SBR工艺系统的TTC-ETS活性,研究了污泥生物活性的变化规律和活性状况。试验结果表明:TTC-ETS活性可以有效地表征SBR系统的生化反应进程;有机物降解、硝化和反硝化阶段的生物活性依次降低,运行条件并未明显影响到SBR系统的TTC-ETS活性变化规律,但影响到TTC-ETS活性曲线上标志不同反应阶段的特征点出现时间和各阶段的平均生物活性;TTC-ETS活性与DO、ORP和pH值之间存在良好的相关关系。
Changing rule and activity status of biological activity of activated sludge in SBR process were studied by the determination of TTC-ETS activity. The resuhs indicate that TTC-ETS activity can reflect effectively the biochemical reaction course of SBR process. Biological activity of organic matter biodegradation, nitrification and denitrification course in SBR process is reduced in order. Operational conditions cannot influence the changing rule of TI＇C-ETS activity, but the time of the appearance of break points marking different reaction course in profile and the average biological activity are influenced There is better correlation between TTC-ETS activity and DO, ORP and pH respectively in SBR process.
