摘　　要：针对炼油废碱液污染浓度高、可生化性差的特点,采用水解与接触氧化组合工艺进行处理。结果表明,废液经水解处理后,COD的平均降解率为12.2%,废水的B/C比由进水的23.7%提高到30.0%;这样,不仅废液的污染程度得到了一定的降低,而且其可生化性也得到了较大的改善。而后续的接触氧化处理使废液的COD和硫化物污染指标平均降解率分别达到25.0%和97.1%。Aiming at serious pollution and no good biochemical quality in refinery alkalinity waste liquid, using hydrolysis-contact oxidation process to treat it. The results showed that the removal percent for COD was 12.2 % and the B/C of the waste liquid was increased from 23.7 % to 30.0 % by hydrolysis treatment. Pollution of the waste liquid was reduced and the biochemical quality was improved. The removal percent for COD and sulfide was 25.0 % and 97.1% respectively by contact oxidation treatment followed.
