摘　　要：利用剩余活性污泥对含有高浓度芳香族化合物的重油裂化制气废水进行预处理的研究并提出了合适的吸附条件。结果表明 ,活性污泥吸附预处理对COD和悬浮物有明显的去除效果 ,而且可以提高废水BOD5/COD的比值 ,另外还有降解芳香族化合物的作用 ,使进入生物处理系统的废水的可生物降解性有明显的改善。这一方法为利用普通废水生物处理系统中产生的剩余活性污泥来预处理难降解的工业废水提供了一条有效的途径。A process for pretreatment of wastewater containing high concentration of hydrocarbons with waste activated sludge adsorption was studied and suitable adsorption conditions were suggested. The results showed that this method could obviously increase removal efficiencies of COD and SS of wastewater, improve the ratios of BOD 5/COD,and make hydrocarbons be decomposed partly, so the biodegradability of wastewater was obviously enhanced. This method demonstrated waste activated sludge could be efficiently utilized to treat recalcitrant industrial wastewater.
