摘　　要：分析了大庆石化公司炼油污水浮选系统的运行情况及影响因素,以及工艺存在问题和采取的措施。结果表明,炼油污水浮选处理,解决了二浮出口含油高问题,使聚合氯化铝铁投加量及乳化物去除率得到降低,能满足污水处理的排放要求,外排水的CODcr指标小于100 mg/L。This paper analyzed the operation status and influencing factors of refinery waste water floatation of Daqing Petrochemical Company,and the problem existed in process and measures adopted. The result showed,the refinery waste water floatation treatment solved the problem of high oil content in the secondary floatation exit,made the ferro-aluminium addition and emulsions removal rate decreased,can meet the requirement for the present waste water treatment with new technology,and CODcr index of uter drainage is not higher han 100 mg/L.
