摘要/Abstract

摘要： 分别以废旧电池中回收的锰氧化物和MnO2为处理剂，对活性艳蓝模拟的染料废水进行了脱色实验。实验结果表明，初始的pH是影响脱色效率的主导因素，当pH＝2，投加量为85mg／L，反应时间t＝33min时，分别通过两个处理剂处理后废水的脱色率都在70％以上，而且通过30min反应后的紫外扫描发现，锰氧化物更有利于染料废水的脱色，为废旧电池资源化利用提供了新途径。

Abstract: KN－R simulated wastewater is treated by using manganese oxides extracted from spent zinc－manganese dry battery and MnO2 respectively. The experimental results show that the initial pH value is the key factor affected decolorization. The removal efficiencies of color are over 75 ％ under the conditions of pH＝2.0, dosages of manganese oxides and MnO2＝80 mg／L, reaction time＝30 min. It is found that the decolorization effect of wastewater using manganese oxides treatment is superior to that of wastewater using MnO2 treatment, which provides a new way of resource utilization of spent dry battery.

Key words: stimulated dyeing wastewater, decolorization, spent dry battery, manganese oxides, MnO2
