摘　　要：提出了一种经济合理的炼油污水深度处理工艺“浮选-生物过滤-臭氧催化氧化-高效过滤”。对辽河石化分公司污水场生化二沉池出水进行了中试处理试验,研究结果表明,出水的主要几项污染指标COD、油、浊度有明显的降低,可达到工业用水的要求。其中,COD由原水的70mg/L～180mg/L降到15mg/L以下,油含量由原水的2.5mg/L～5.6mg/L降到0.5mg/L以下,总铁离子由原水的1.5mg/L降到0.3mg/L以下,总磷由原水的1～1.5mg/L降到0.5mg/L以下,试验效果比较理想。The thesis introduce a economical reasonable technological process of deep treatment refinery waste water' upper flotation - upper biofilter- ozon e catalytic oxidation reactor - superfilter'. After treating secondary clarifier effluent ofsewage disposal plant in LTAOHE petrochemical branch campany by this process, the result of study indicate that there is aevident decline in several main pollution target such as chemical oxygen demand (COD) ,oil,turbidity, this process can satisfy the demand for the industrial water. A better result is attained in the aspect of COD from 70~180mg/L to 15mg/L,the content of oil from 2.5~5.6mg/L to 0.5mg/L or so,tubidity from24 - 33mg/L to 0.5mg/L,total ironion from 1.5mg/L to 0.3mg/L,total phosphorus from 1~1.5mg/L of effluent.
