摘　　要：采用生物曝气滤池(BAF)工艺对某炼油厂轻度污染水进行了生物处理现场试验研究。试验结果表明:BAF工艺能有效地降解水中的污染物质。在水力停留时间为1.0h,气水比为5的条件下,某炼油厂轻度污染水中CODCr,石油类和SS的平均去除率分别为84.5%,94.0%和83.4%。Biological Aeration Filter (BAF) process was used in an on-the-spot test of the biological treatment of the slightly-polluted water in a refinery. The result of the test showed that the BAF process effectively degradated the pollutants in the water, and that when the hydraulic retention time was 1.0 hour and the air-to-water ratio was 5, the average removal rates of CODCr, petroleum oils and SS in the slightly-polluted water in the said refinery were 84.5%, 94.0% and 83.4% respectively.
