摘要：铁炭微电解法被广泛应用于废水处理工程中,具有设备简单、操作方便、运行费用低等优点。以三氯甲烷、氯乙酸目标物质,研究了铁炭法对这2种物质的脱氯效果、脱氯机理,考察了停留时间、pH、浓度对脱氯效果的影响。实验结果表明:铁炭法对三氯甲烷、氯乙酸有明显的脱氯作用;脱氯机理主要是基于零价铁的还原作用。脱氯效果与含氯有机化合物的结构有一定的关系。
Application of iron scrap fillings to reductive dechlo-rination of chlorinated compounds such as chloroform and chloroactic acid has been studied. Iron scrap fillings could dechlorinate the chlorinated organic compounds well, such as under the conditions of pH=2 -3, HRT=2 - 2.5h, the removal rate of chloroform and chloroacetic acid could reach 20% - 30% and 30% - 40%. The mechanism of dechlorination was based on the reduction of zero-valent iron. The statistics showed that the treatment efficiency was related to the struc-ture of the chlorides.
