摘要(Abstract)：

采用溶液吸收结合铁碳微电解反应处理气流中的三氯乙烯(TCE)废气。实验采用管式反应器,管内分别充填铁屑、活性碳和铁屑-活性炭(Fe-AC)组合填料,所有填料浸没在酸性吸收液中。含有TCE的气体从反应器下部导入,经铁屑-活性炭(Fe-AC)微电解区后,从反应器上部排出。研究了铁屑、活性炭及铁屑-活性炭(Fe-AC)组合三种条件下对TCE的去除效果,考察了溶液pH对TCE去除率的影响。实验结果表明采用Fe-AC组合对TCE废气的去除率要高于在溶液中分别添加铁屑或活性炭的情况,在铁屑和Fe-AC作用下的吸收液中均测得氯离子存在,表明铁屑和Fe-AC体系都具有脱氯还原的效果,而Fe-AC微电解对TCE的脱氯效果更好;较低的pH值有利于提高TCE的还原脱氯和去除效果。
