上海石化自20世纪70年代建厂以来,按照《中华人民共和国环境保护法》、《建设项目环境保护管理条例》等法律法规,在建设生产装置的同时,建设环境保护设施,做到同时设计、同时施工、同时投产使用,并根据《水污染防治法》、《废水排放标准》等,组织废水的治理和排放管理。30多年来,上海石化的废水排放基本实现浓度控制和总量控制的双达标。上海石化生产装置多,产品种类多,因此,产生的废水种类也多,各自的组成成分也有较大的差异。废水的主要成分有:油类(原油、煤柴油、重油);腈类(乙腈、丙烯腈、氢氰酸等);醇类(甲醇、异丙醇、乙二醇等);醛类(甲醛、乙醛、丙烯醛等);芳烃类(苯、甲苯、二甲苯、酚等);重金属(铜、锌、铬、铅等)。废水治理设施经过不断的发展和建设,废水排放管理体制经过不断的完善与改进,形成了目前的废水治理模式。不容置疑的是,该模式为上海石化废水的双达标排放做出了贡献。当然,上海石化也为此付出了相应的财力、人力和其它资源。
Since its establishment in the 1970s, Shanghai Petrochemical has built environmental protection facilities in line with laws and regulations such as “Environmental Protection Law of the People’s Republic of China” and “Regulations on Environmental Protection of Construction Projects”. At the same time, At the same time construction, and put into operation at the same time, and in accordance with the “Water Pollution Prevention Law”, “Wastewater Discharge Standards” and other organizations waste water treatment and emission management. For more than 30 years, Shanghai Petrochemical’s wastewater discharge basically achieved the double standard of concentration control and total quantity control. There are many production facilities in Shanghai Petrochemical Company and many kinds of products. Therefore, there are many kinds of waste water produced, and their respective compositions also have big differences. The main components of wastewater are: oil (crude oil, coal diesel, heavy oil); nitriles (acetonitrile, acrylonitrile, hydrocyanic acid and the like); alcohols (methanol, isopropanol and ethylene glycol); aldehydes , Acetaldehyde, acrolein, etc.); aromatic hydrocarbons (benzene, toluene, xylene, phenol, etc.); heavy metals (copper, zinc, chromium, lead, etc.). After continuous development and construction of wastewater treatment facilities, the wastewater discharge management system has been continuously improved and improved to form the current waste water treatment mode. There is no doubt that this model has contributed to the double discharge of Shanghai Petrochemical wastewater. Of course, Shanghai Petrochemical also paid the corresponding financial resources, manpower and other resources.
