文档介绍：某炼油污水处理站设计
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Ⅱ级标准。
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。

THE DESIGN OF TREATMENT STATION ON OIL REFINERY WASTEWASTER
ABSTRACT
Refinery sewage generated form the chemical industry production and operation, which can not be the direct use. It is the domestic industry wastewater. Refining industry is more serious environmental pollution industry. There are some factors causing environmental pollution in the processes from raw materials to products, from production to use.
The oil refining sewage quality and plexly changes by the impact of the technology and production, concentration anic pollutants is different. At present, domestic treatment methods on refining wastewater were the biological and chemical methods, supplemented by physical methods such as ulation, sedimentation, and so on.
In this design, biochemical and physiochemical methods are used, which can ensure the quality of drained water. But there are also some weakness, such as pared with some advanced process, certainly, it also has a lot of advantages, for example, its process is economical, and just this one conform to the fact of our country. Following is the technological process. After treatment, the treated water can meet the ‘second grade standard of the national second class discharge.’
Influent → Grille → Conditioner → oil Separator → Flotation cell → Bio-pilot → Setting Basin → effluent
The design detailedly described the selection and demonstration of the design project, the design account of structures, the layout of treatment station, the elevation layout and content, such as budget for the project, respectively.
