3、ch 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 an
4、d quantity complexly changes by the impact of the technology and production, concentration of organic pollutants is different. At present, domestic treatment methods on refining wastewater were the biological and chemical methods, supplemented by physical methods such as flocculation, 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 its complication compared with s
