摘　　要：碱减量废水的主要成分是对苯二甲酸及其钠盐,影响碱减量废水处理效果的重要因素之一是对苯二甲酸及其钠盐质量-体积分数过高。采用生化法和铁碳法进行对苯二甲酸废水的处理研究,结果得出:CODCr=2000mg/L是微生物降解对苯二甲酸的抑制质量-体积分数;pH值为8～9时活性污泥处理对苯二甲酸废水比较理想;铁碳法处理对苯二甲酸废水35h后,CODCr的去除率达到了80%以上。Terephthalic acid and its sodium salts are the main components of alkali reduction wastewater, their high concentration is one of the most important affecting factors on the treatment effect.Biochemical method and Fe-C method were used for the treatment of terephthalic acid wastewater. The result indicates that 2000 mg/L of CODCr value is the restraining concentration of microbe degradation. Active sludge has the perfect treatment effect on the tereph-thalic acid wastewater at pH value of 8～9.Fe-C method has a good removal effect on the treatment of terephthalic acid wastewater, the removal of CODCr can reach 80% or more after 35 hours.
