摘要
提出一种微波强化内电解处理染色废水的新方法,结果表明微波不仅可以再生炭铁混合物,而且可以氧化分解活性炭吸附的染料;铁屑不仅与活性炭构成内电解作用同时还可以促进微波再生活性炭;微波作用多次后炭铁混合物对废水的去除率仍能保持色度去除率99%、COD去除率64%;探讨了微波作用时间、微波作用次数、铁屑粒径、炭铁比例、pH值等因素对废水去除率的影响。并初步探讨了其反应机理。
This paper presents a new method of treating dye wastewater by applying microwave (MW) in order to intensify internal electrolysis. The experimental results indicate that MW not only reactivates the mixture of carbon and iron(AC/Fe), but can also decompose dye adsorbed onto the AC. Electrolysis will be increased when Fe is mixed with AC,and at the same time the AC can be regenerated more easily by MW energy. The percentage of decolorisation of the dye solution can be over 99% and the reduction in CODcr is over 64% when MW irradiated AC/Fe is used. The relationship between degradation efficiencies and those factors such as MW irradiation time, number of treatment passes, particle size of Fe, proportions of AC to Fe and the pH are discussed.
