摘要：
介绍了一种电化学-层柱累托石吸附法处理含铬电镀废水的新工艺;并对其影响处理效果的因素进行了探讨。在1L含Cr(Ⅵ)41mg,pH为0.96的电镀废水中加入0.3g微电池反应物TX,进行电化学处理60min;然后用15g层柱累托石常温振荡吸附30min,出水中Cr(Ⅵ)质量浓度降至0.2mg/L以下,达到国标GB8978—1996一级排放标准要求。在此基础上,我们与湖北荆州罗场镀膜厂合作进行了日处理10～15t,铬质量浓度为13～60mg/L电镀废水的工业试验。近1a的运行结果表明:出水水质均达到国标一级排放标准,说明该工艺对处理电镀厂废水具有明显的效果,具有广泛的开发和应用前景。

Abstract:
The new removal technology of Cr (Ⅵ)from electroplating wastewater by micro-batteries and pillared rectories adsorption is introduced.Its effect factors are also studied.0.3g of TX is added to one liter electroplat-ing wastewater which contains41mg of Cr (Ⅵ),its pH=0.96,reacting for60min.Then,at room temperature,15g of pillared rectories is added to the wastewater which has been treated by micro-batteries,letting it be surged and adsorbed for30min.The concentration of Cr (Ⅵ)in the outgoing water decreases to less than0.2,lower than the National First Grade Discharge Standard,GB8978-1996.Based on this,10～15of electroplating wastewater,whose concentration of Cr is13～60mg /L,is treated by us in collaboration with Luochange Chrom-eplating Factory in Jingzhou City,Hubei Province.The result gained in the one-year running shows that the qua-lity of outgoing water has reached the National First Grade Discharge Standard.It has remarkable effect on the tr-eatment of electroplating wastewater.Its development and application prospects are extensive.
