含生物活性介质废水体系的流变行为研究

研究了含生物活性介质废水体系的流变行为 ,考察了污泥浓度、体系 pH值、温度等因素对废水体系流变行为的影响。实验结果表明 :体系粘度随着污泥浓度的增加而变大 ;也随着pH值的增加而变大 ;温度升高 ,污泥粘度相应会变小 ;同样污泥浓度的体系粘度 ,厌氧条件下比好氧条件要低。研究结果可为生化法中的氧气、污染物传递过程计算和生化反应器设计提供理论基础。

STUDY OF RHEOLOGIOAL BEHAVIOR OF WASTEWATER SYSTEM WITH BIOLOGICALLY ACTIVE MATTERS

In this paper, the theological behaviors of the wastewater system containing biologically active matters have been researched. The effects of the concentration of the sludge, pH, temperature and other factors on the rheolngical behavior of the wastewatar system were examined. The experlment results show that dynamic viscosity increases as the concentration of the sludge and pH increase. Dynamic viscosity reduces when temperature rises, and dynamic viscosity reduces when the system is in the anoxic condition. The achievements will provide the theoretical principles to the calculation of the transferring of oxygen and contaminant.
