摘　　要：针对某酒精厂在酒精废醪干燥回收过程中的蒸发排水的特点,选择电解混凝+复合生物氧化+混凝气浮为主要处理工艺对原有废水处理设施进行工程改造。120 h的连续运行结果表明,该工艺的平均出水COD浓度为100mg/L。对工程运行过程中出现的异常原因及改造后存在的不足也进行了分析,以供类似工程及工程改造作参考。Aiming at the characteristics of vaporizing discharge from a corn distillery spent wash, a process of＂electrolysis and coagulation ＋ hybrid biological oxidation ＋ coagulation flotation＂ was used for the reform of the existing wastewater treatment plant. In the technological process after reform, the effluent mean COD reached to lOOmg/L. In addition, some abnormal phenomena and insufficiencies appeared in course of operation were analyzed to provide the reference for the reform of similar project.
