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85 mg/L,反应时间t=33 min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30 min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。

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.
