摘　　要：采用混床和螯合树脂串联的软化工艺对某采油厂稠油污水进行处理研究,探讨了混床中阳阴树脂配比(1∶1双层床、1∶1混床、3∶2混床和3∶1混床)对两级软化系统出水硬度、UV254、pH和电导率的影响。结果表明,阳阴树脂比例为3∶2的混床加螯合树脂工艺的出水硬度、UV254、pH和电导率在4组平行交换柱中均表现出比较明显的优势,出水水质最好,出水硬度保持在50μg/L以下;除3∶1比例的混床外,其他配比混床的UV254最大去除率都达到50%以上。A softening process of mixed bed and chelating resin operated in series has been used for carrying out an experimental study on the treatment of heavy oil wastewater discharged from an oil production plant. The effects of mixed ratio （ 1 ： 1 two-layer bed, 1 ： 1 mixed bed, 3 ： 2 mixed bed and 3 ： 1 mixed bed） of cation exchange resin and anion exchange resin on the hardness, UV254,pH and conductivity of the effluent of the two-electrode softening system are discussed. The results indicate that the effluent hardness, UV254, pH and conductivity of the mixed ratio of 3 ： 2 shows an obvious advantage and has the best effluent quality in the four groups parallel exchange columns. In particular, the effluent hardness could keep at 〈 50 μg/L in the whole experimental process. Except the mixed ratio of 3 ： 1, the maximum removing rate of UV254 could reach 〉50% for the other ratios of mixed bed.
