摘　　要：重金属废水成分复杂、毒性大且难降解,随着国家相关法律政策要求日益严格,使之成为废水治理的重点和难点。目前,活性炭吸附法在重金属废水处理方面也逐步开始工业化应用,取得较好的效果,本文对现有活性炭处理重金属废水技术进行了综述,详细讨论了该技术的各项参数,包括:活性炭的选择及预处理、废水的pH值、停留时间、活性炭用量和吸附柱的运行条件等,并简要介绍了活性炭吸附处理重金属废水的吸附机理。Heavy metal ions in wastewater have complicated component,serious toxicity and difficult to be degradated.With increasingly rigid requirements of relevant laws and policies,heavy metal contaminated wastewater treatment became focus and difficulty.Recently,adsorption technology on activated carbons was applied to treat heavy metal contaminated wastewater and had received successful achievement.The factors that affect the technology were discussed,including the selection of activated and its pretreatment,the pH value of wastewater,residence time,the dose of activated carbon,operating conditions of adsorption column and adsorption mechanism was briefly described.
