【摘要】 以奥里油为原料生产重交沥青时所产生的废水与一般炼油废水不同,其是一种含有大量表面活性剂、高有机污染物的重污染废水。选用好氧和厌氧生物处理的方法对奥里油废水进行了初步试验研究。研究结果表明:奥里油废水具有一定的可生化性,可以采用生物处理的方法进行净化处理。该废水经过生物处理后,原水COD可从5 677mg/l下降到500mg/l左右,COD去除率可达90%以上。更多还原

【Abstract】 The wastewater from the process of producing heavy bitumen with Orimulsion is quite different with the common wastewater of oil refinery.The Orimulsion wastewater is a kind of heavily polluted wastewater with a great deal of surfactant and high concentration of organic pollutant.The wastewater was treated by the processes of aerobic and anaerobic biological treatment.The results show that the wastewater has some biodegradability and can be treated by biochemical method.The concentration of COD can be removed from 5 677 mg/L to about 500 mg/L after treated by biological treatment,and the efficiency of COD removal is more than 90%.更多还原
