升流式厌氧污泥床反应器改进方法探讨

Study on The Improvement Method of Up-flow Anaerobic Sludge Blanket Reactor

针对升流式厌氧污泥床反应器(UASB)启动时间长、上升流速小、混合效果差等缺点,提出了对反应器的改进方法,并对改进后装置进行了气含率、循环液速等动力学参数的测试分析,结果表明改进后的试验装置可提高上升流速、优化混合效果,有利于培养颗粒污泥。

According to the disadvantages of UASB reactor, such as long time in starting, small upflow velocity, bad mixing effect, a method to modify reactor is point out , the kinetic paramaters of unit after improved such as gas holdup and liquid circulation rate is determined. The result shows that the unit after improved can increases upflow velocity, optimizes mixing effect, it is beneficial to culture the granular sludge.
