摘 要: 针对石油炼制废水污染严重、可生化性差的问题,采用厌氧水解酸化工艺进行处理。结果表明,废水经水解酸化处理后,COD和石油类的去除率分别达到46 5%和67 3%,废水的B/C由进水的27 9%提高到34 4%。这样不仅废水的污染程度得到了一定的降低,而且可生化性也得到了较大的改善,为后续生化处理奠定了较好的基础。 Aiming at serious pollution and no good biochemical quality of oil refinery effluent, which was treated by hydrolytic acidification in this study. The results showed that the removal rates for COD and oil was 465% and 673%, respectively and the B/C of the effluent was increased from 279% to 344% by hydrolytic treatment. Pollution of the effluent was reduced and the biochemical quality was improved, a stronger foundation was laid for biochemical treatmnet followed.
