摘　　要：《石油炼制工业污染物排放标准》(GB 31570—2015)对总氮提出了明确的管控目标,某石化公司浓水处理系统在新标准出台前进行提标改造,在原有工艺的基础上增加反硝化生物滤池和砂滤罐等设施,采用臭氧氧化、反硝化、气浮、砂滤、活性炭的工艺对反渗透浓水进行处理,操作运行稳定,出水水质良好,污水外排连续五年稳定达标,提标改造经验可供其他企业借鉴参考。The Emission Standard of Pollutants for Petroleum Refining Industry(GB31570-2015)sets clear control targets for total nitrogen.One petrochemical company carried out standard upgrading before the new standard was issued.On the basis of the original pro-cess,facilities involving denitrification biological filter and sand filter tank were added.The reverse osmosis concentrated water was treated by ozone oxidation,denitrification,air floatation,sand filtration and activat-ed carbon.After such revamp,the operation has been stable;the quality of effluent has been good and the effluent discharge of sewage has reached the standard steadily for five consecutive years.The experience of such revamp after standard upgrading can provide ref-erence for other enterprises.
