摘要：

开展了膨胀颗粒污泥床(EGSB)反应器处理煤制油费托合成废水的试验研究.启动过程先以费托合成废水稀释水样作为反应器进水,并逐步降低稀释比,直至以费托合成原水作为进水.试验结果表明,反应体系pH和容积负荷对EGSB反应器启动的影响较大,启动过程中应控制反应器内pH为7.0~8.5,容积负荷在29 kg/(m³·d)以内.

Abstract:

The expanded granular sludge bed(EGSB) reactor has been used for treating Fischer-Tropsch(F-T) wastewater. In the start-up process,the F-T wastewater diluted water samples should firstly be used as the influent of the reactor,and the dilution ratio should be lowered gradually,till F-T wastewater is used as influent. The experimental results show that the pH and volume load of the reactor system have rather serious in fluences on the start-up of EGSB reactor. In the start-up process,the pH in the reactor should be controlled as 7.0-8.5,and the volume load should be controlled as lower than 29 kg/(m³·d).

Key words: Fischer-Tropsch wastewater, expanded granuler sludge bed, start-up
