摘要
采用接触氧化—曝气生物滤池—加氯氧化—砂滤—活性炭吸附的工艺对某炼油厂污水进行处理,运行结果显示:出水中石油类和SS均小于5mg/L,达到了设计回用指标;而对COD和氨氮的降解则存在不稳定现象,针对此问题作了进一步的工艺整改后此工艺最终出水可以达到该厂制定的回用水质标准。
The process of contact oxidation - biological aerated filter-chlorination-sand filter-active carbon adsorption was used for treatment of refinery waste water. Focused on the process that petroleum≤5mg/L and SS≤5mg/L, meeting the design indices while COD and NH3-N were not stable, the process was further optimized. The result showed that the effluent quality met the recycled water standards of the refinery.
