活性污泥法石化工业废水处理动力学研究

Kinetic Study of Petrochemical Waste Water Treatment by Activated Sludge in Column Reactor

利用活性污泥对石化工业废水进行降解研究 ,发现其降解过程反应遵循一级宏观反应动力学关系。计算了在各种操作条件下的反应速率K。通过比较反应速率K的大小 ,得知塔式曝气的效率远远高于传统的曝气池 。

The degradation of petrochemical waste water was investigated in activated sludge system by using an aeration column.It was found that this degradation process followed one order reaction kinetics.The reaction rate coefficients under different conditions and in different reactors were calculated based on the experimental measurements.The results indicate that the loop aeration column possesses significantly higher reaction rate than other aeration reactors.
