摘　　要：利用微电解法预处理难生化降解的印染废水,对影响微电解效率的因素进行了研究。结果表明:在印染废水的pH为4,作用时间为60min,铁炭的质量比为2∶1时,微电解法对难生化降解的印染废水的色度、CODCr的去除率分别达到96%和65%,BOD5/CODCr的比值由0.19提高到0.42,预处理后的印染废水的可生化性能明显提高。in this paper, a pretreatment of printing and.dyeing wastewater was applied by micro-electrolysis method. And it explored the influence factors on micro-electrolysis efficiency. It was found that at the pH of printing and dyeing wastewater 4, quality ratio of iron to charcoal 2 ＂ 1, and treating for 60 min, the removal rate of chromaticity and CODc, of the waste water can be up to 96% and 65%, respectively. And the ratio of BOD5/CODCr increased from 0.19 to 0.42. The biochemical degradation performance of treated printing and dyeing wastewater was increased greatly.
