摘要
针对实际印染废水,采用催化铝内电解法,在曝气和无曝气条件下进行对比试验,测定了处理前后废水的COD、BOD、色度、pH等指标。结果表明,曝气催化铝内电解工艺优于不曝气的工艺,对废水中COD、色度的去除有显著提高,且两种工艺处理后的印染废水的B/C值均达到0.3左右,有利于后续生化处理。
Aeration and no aeration are used in catalytic aluminum inner electrolysis process for dyeing wastewater, the treatment effects were compared by various of indexes such as COD, BOD, colority, PH etc. The results of experiments show that, the removing COD, colority in wastewater are remarkably efficient.The process with aeration is better than the process without aeration. The B/C values of dyeing wastewater treated by two different process all reach about 0.3, which is helpful to the following biochemistry processing.
