作为石油工业的下游工艺,石油炼制工业有着复杂的工艺流程,运用物理和化学工艺通过蒸馏、提取和分离的过程,然后进一步加工分离得到的产品最终制成汽油、柴油等产品。但是在石油工业生产过程中产生了大量的污水其中以炼制过程最为严重,而且难于降解,本文将重点介绍目前几种常见而且取得良好效果的污水处理办法以供参考。 As a downstream process of the petroleum industry, the petroleum refining industry has a complex process, using physical and chemical processes through the process of distillation, extraction and separation, and then further processing of the resulting product to produce gasoline, diesel and other products. However, a great deal of sewage is produced in the process of petroleum industry. Among them, the refining process is the most serious and difficult to be degraded. This article will introduce several common and well-performing sewage treatment methods for reference.
