EGSB反应器处理煤制油费托合成废水的研究

Treatment of Fischer-Tropsch wastewater by expanded granular sludge bed(EGSB) reactor

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29kg／（m3·d）以内。

The expanded granular sludge bed（EGSB） reactor has been used for treating Fischer-Tropsch（F-T） waste- water. 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 infiuent. 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 titan 29 kg/（m2·d）.
