摘　　要：为对焦化废水中难降解物质进行处理,提高其废水可生化性,将铁炭微电解法应用于焦化废水处理。该试验研究了影响处理效果的因素,并对废水中有机物的去除、脱色效果以及废水可生化性的提高进行了探讨。结果表明:在初始pH值为3,反应时间为180min,铁炭质量比为2∶1时,试验对CODCr和色度的去除率分别达到70.3%和85.0%,BOD5与CODCr质量浓度比值从0.21提高到了0.56。In order to treat the difficult degradation material in the coking waste water and to improve the biodegradability of the waste water, the iron carbon micro-electrolytic process was applied to treat the coking waste water. The experiments had studied the factors affected to the treatment results. The paper had a discussion on the organic material removing from the waste water, decolorization and biodegrad- ability improvement. The results showed that at the initial pH value was 3, the reaction time was 180 min and the iron and carbon ratio was 2： 1, the CODe, and colour remove rate of the experiments were 70. 3% and 85.0% individually and the mass concentration ratio be- tween BOD~ and CODer could be improved from 0. 21 to 0. 56.
