摘　　要：采用微波等离子体强化内电解技术处理活性艳蓝KN—R溶液,考察活性炭、铁屑、体积比为1:1的铁碳混合物在单纯反复内电解(吸附)和微波等离子体再生反复内电解(吸附)中的脱色率和CODCr去除率。结果表明:铁碳混合物反复微波再生利用四次,脱色率仅下降了3.92%,CODCr去除率也仅下降了8.03%,比同等条件下的单独活性炭和单独铁屑都要好。从SEM分析上可以看到,经过微波等离子体再生处理,活性炭内部孔隙增大,铁屑表面遍及峰窝状凹孔,比表面积增大,内电解效率提高。This study applied the microwave plasma technology to treat reactive brilliant blue KN-R solution. The absorbance of the solution ,the rate of reduction of CODCr were recorded whilst varying specifc experimental factors: the use of active carbon, iron and then a mixture of both were investigated under repeated internal electrolysis(absorption)or repeated microwave plasma regenerative internal electrolysis (absorption). The results of this study indicate that the degradative effect of the mixture of active carbon and iron is better than the two components on their own sole. After regenetating four times,the absorbant removal degradated 3.92%,CODCr removal degradated 8.03% only. From SEM analysing figure,We can see the inner micropore of active carbon become larger,the appearance of iron speaded sunken point like honeycomb all over,surface area and the efficiency of inner electrolysis of iron all increased.
