摘要
采用电絮凝法处理废纸脱墨废水。探讨了电极材料、电流密度、极板间距、体系的pH值、电解时间等对废水处理的影响。结果表明,用铝为电极材料,在电流密度1.7A/dm3、极板间距10mm、体系pH5～6.5和电解时间20min的条件下,可获得良好的处理效果,废水的浊度去除率和COD去除率分别可达95%和60%。
The electroflocculation was utilized in treatment of wastewater produced in deinking for wastepaper.The factors affecting efficient of treatment,such as electrode material,the space between electrodes,pH in system,the time of electrolysis,were investigated.It was found by the experiments that it is satisfactory that using aluminum as electrode material and adjusting current density and electrode space to 1.7A/dm3 and 10mm,respectively,electrolysis is performed for 20 minutes in wastewater of pH5～6 5.The result obtained showed that the removal efficiencies of turbidity and COD reached 95%and 60%,respectively.
