炼油厂废水的处理及研究现状

Treatment and research status of refinery wastewater

近年来中国对废水治理要求日趋严格,诸多地方炼油企业普遍存在处理工艺落后的现象。为实践节能减排理念、保证国内环保要求,废水处理达标排放已成为了炼油企业重要的环保节能事项。针对当前国内炼油厂生产的废水现状,文中介绍了含硫废水、含盐废水、碱渣废水等炼油废水的来源和主要污染物,系统论述了炼油企业污水处理厂废水处理现状,即2级和3级处理工艺,并对其研究应用现状进行了分析。同时,对炼油废水处理趋势和技术路线进行了展望。

In recent years,the wastewater treatmentrequirements in China have become increasingly strict,and the treatment technologies adopted by many local refineries generally were outdated.In order to practice the concept of energy conservation and emission reduction and ensure domestic environmental protection requirements,wastewater treatment and discharge up to standard had become an important environmental protection and energy saving matter for refineries.In view of the current situation of waste⁃water produced in domestic refineries,this paper introduced the sources and main pollutants of oil refining wastewater such as sulfur wastewater,salt wastewater and alkali slag wastewater,systematically discussed the status quo of wastewater treatment in oil refining wastewater treatment plants(level 2 and 3 treatment processes),analyzed the research and application status,and prospected the trend and technical route of oil refining wastewater treatment.
