                           活性炭吸附法处理含铬废水的应用
                          在工业生产中,电镀是必不可少的环节,随着电镀业的迅猛发展,大量的电镀废水对人类环境造成越来越严重的危害。在含铬电镀废水中,含有大量铬(V I)及少量的金属阳离子和阴离子,如不经处理直接排放,将造成严重的水环境污染。
                          铬是电镀中用量较大的一种金属原料,在废水中六价铬随pH 值的不同分别以不同的形式存在;钚蕴坑蟹浅7⒋锏奈⒖捉峁购徒细叩谋缺砻婊,具有极强的物理吸附能力,能有效地吸附废水中的Cr ( )Ⅵ ;钚蕴康谋砻娲嬖诖罅康暮趸湃玺腔- OH) 、羧基(-COOH) 等,它们都有静电吸附功能,对Cr ( )Ⅵ产生化学吸附作用。完全可以用于处理电镀废水中的Cr ( )Ⅵ ,吸附后的废水可达到国家排放标准。 试验表明:溶液中Cr ( )Ⅵ 质量浓度为50 mg/ L , pH = 3 ,吸附时间1. 5 h 时,活性炭的吸附性能和Cr ( )Ⅵ 的去除率均达到最佳效果。因此,利用活性炭处理含铬废水的过程是活性炭对溶液中Cr( )Ⅵ 的物理吸附、化学吸附、化学还原等综合作用的结果;钚蕴看砗醴纤,吸附性能稳定,处理效率高,操作费用低,有一定的社会效益和经济效益
