1、炼油厂污水处理站工艺设计摘要:炼油污水是炼油化工行业生产、运行过程中产生的不可直接利用的污染水,它是国内工业废水的重要组成部分。炼油行业是环境污染较为严重的行业,从原料到产品,从生产到使用,都存在造成环境污染的因素。受生产工艺和产品的影响,炼油污水的水质、水量变化复杂,有机污染物浓度不同,是难处理的工业废水之一。目前,国内炼油污水处理手段以生化为主,辅以一些物理方法如絮凝、沉淀等。本工艺设计针对炼油污水的水质、水量的特点,力求做到经济、高效,采用了传统的、有成功设计、运行经验的活性污泥法,辅以物理方法;生化部分采用改造的多点进水的运行
2、方式,工艺流程见如下,处理后出水可达到国家石油化工行业污水排放一级标准。格栅—调节池—平流式隔油池—混合反应池—气浮池—生物接触氧化池—二沉池—达标排放本设计说明书较全面地叙述了设计方案的选择与论证、处理构筑物的设计计算、处理站平面布置和高程布置及工程概算等内容。关键词:炼油污水,处理站,隔油,生物接触氧化PuyangrefineryprocessdesignsewagetreatmentstationAbstract:Thechemicalindustry,oilrefineryproductionandrefinerywastew
