摘要
初步分析了奥里油废水的水质，研究了用酸改性粉煤灰处理奥里油废水的工艺。奥里油废水是一种含有一定表面活性剂、高COD值（大于6000mg／L）、难生物降解和难03氧化降解的炼油废水。利用改酸性粉煤灰可对该废水进行预处理，COD去除率达45％。预处理工艺条件是，室温下灰水质量比15：50，吸附搅拌时间30min，pH为2～10。
The Orimulsion wastewater is a kind of refinery wastewater with some surface active agents and high concentration of COD（Chemical Oxygen Demand）, which more than 6000 mg/L. The quality of the wastewater analysis showed that the Orimulsion wastewater was hard biodegradation and hard oxidative degradation by 03. The acid-modified fly ash was used to pretreat the Orimulsion wastewater. At room temperature the pretreatment conditions were 15 g（acid-modified fly ash）/50 g （Orimulsion wastewater）, pH is 2-10 and 30 min for adsorption, the efficiency of COD removal was more than 45%.
