摘　　要：针对玉门炼油厂污水处理系统无法稳定达标排放的问题,通过改造调节池、建造北路污水提升池、提高浮油去除效率、应用加压式溶气气浮、采用厌氧生物处理技术、采用BAF与蠕动床结合技术、新建污泥处理系统等措施,大幅度提高了总排出水质量,装置总排出水中石油类、COD、BOD5、硫化物、悬浮物、氰化物、氨氮、挥发酚质量浓度分别为0.71,54.00,29.7,0.02,14.67,0.04,0.48,0.27mg/L,pH值为7.37,满足GB 8978—1996排放标准,为污水回用奠定了基础。Due to the effluent from wastewater treatment system of Yumen Refinery could not meet the emission standard steadily, some countermeasures were adopted, such as revamping the regulating pool, building north sewage lifting pool, enhancing the removal rate of floating oil, applying pressurized dissolved air floatation, using new anaerobic biological treatment, combining peristaltic bed and BAF treating technology and setting up a new sludge treatment system. Since then, the quality of total dis- charge water is improved greatly with hydrocarbons of 0.71 mg/L, COD of 54.0 rag/L, BOD5 of 29.7 rag/L, sulfide of 0. 02 rag/L, suspended solids of 14.67 mg/L, cyanide of 0.04 mg/L, ammonia-nitrogen of 0.48 mg/L, volatile phenol of 0.27 mg/L and pH value of 7.37, which well meet the requirements of national emission standard （GB 8978-1996） and it also provides the feasibility of recycling discharge water.
