摘    要:以活性艳红X-3B为主要对象,在传统的内电解处理法的基础上,利用微波使铁炭床再生,强化处理染料废水,并初步探讨铁炭内电解和微波强化的作用机理。实验结果表明,在铁炭体积比为4:3,铁屑粒径为2-4mm,染液pH为5,反应时间为90min时,处理染料浓度为0.75g/L的染液,CODCr的去除率可达80%以上,脱色率也达99%。在最佳反应条件下研究微波对铁炭床的强化作用,结果显示原始的铁炭床可以重复使用4次以上,当处理效果有明显下降时,利用微波再生铁炭床2min,处理效果恢复,且还可继续使用两次,再次再生,铁炭仍有一定的处理效果。微波不仅加强了铁炭床的处理效果,还延长了铁炭床的使用周期。

关 键 词:铁屑  焦炭  微波  活性艳红X-3B

Abstract:This paper has showed a new method of applying iron (Fe) and coke (C) intensified by microwave to treat reactive X-3B dye wastewater. The mechanism of inner-electrolysis and microwave intensify has been discussed. The results showed on the condition that proportions of Fe to C was 4:3,particle size of Fe was 2-4mm,pH value was 5 and the reaction time was 90 min, the percentage of CODcr removal was more than 60% and decolorisation of the dye solution could be 99%. The results showed that original iron and coke could be used more than 4 times. When there was a marked drop in the effect, the mixture of iron and coke was irradiated for 2 minutes by MW for regeneration. We found the effect could be resumed, and the mixture of iron and coke could be used for more than 2 times. It showed that MW could not only intensify the effect, but also prolong the cycle of the mixture of iron and coke.
Keywords:iron  coke  microwave  active red X-3B
