摘要
为评价吸附后活性炭再生效果,对吸附重金属离子活性炭的再生工艺进行了研究。考察了各因素对再生活性炭性能的影响。结果表明:升高再生温度及延长再生时间,活性炭质量损耗率随之上升,活性炭性能恢复率随之增加。增加再生次数,活性炭质量损耗率随之上升,活性炭性能恢复率随之降低。
In order to evaluate the regeneration effect of activated carbons（ACs）after adsorption,the regenerationtechnology of activated carbon loaded with heavy metal ions has been studied. The influences of various factors onthe performances of regenerated activated carbon are investigated. The results show that mass loss rate andcapability recovery rate of ACs increase with the increase in regeneration temperature and regeneration time. Withthe increase of the number of times,the mass loss rate of ACs increases and the capability recovery rate of ACsdecreases.
