摘要
目前大多数炼油厂污水经二级处理工艺进行处理后直接排放,其中的污染物仍会影响环境并消耗大量水。随着水资源的日益短缺和对石油产品需求的持续增加,加大了炼油企业的污水处理量和工业用水总量。研究适宜的污水深度处理工艺以保证炼油污水循环回用是十分必要的。并结合国内外的实际情况介绍了90年代以来多种炼化污水回用的深度处理技术,可以作为相关污水回用处理方法选择的参考。
Nowadays most refi - ning sewage is directly drained after secondary disposal. However it still contains some contaminant that hardly meets the environmental requirement and a vast amount of water was wasted. With the shortage of water and the increasing demand of oil product gradually, the refineries have much stress on the treatment amount of wastewater and demand of water. So, it is essential to seek out a suitable advanced treatment process that may deeply dispose the reused wastewater. Combing with the facts in our country, several method and technologies of advanced treatment and reuse of the oil refining sewage that are developed froml990 are introduced in this article.
