Experiments of ferrite process treating manganese-containing wastewater in electrolytic manganese industry
Pages: 24-26,32
Year: Issue:  1
Journal: Environmental Protection and Technology

Keyword:  电解锰废水Mn2+铁氧体;
Abstract: 研究铁氧体法处理含Mn2+废水的工艺条件,详细分析了Fe2+ /Fe3+、Fe2 +/Mn2+、pH值、温度等因素对Mn2去除率的影响.得出最佳工艺条件为:Fe2+/Fe3+(摩尔比)=1∶3、Fe2+/Mn2+(摩尔比)=10:1、pH=11、温度=50℃,Mn2+的除去率达到99%.使用该工艺处理含Mn2废水,出水水质达到GB 8978-1996《污水综合排放标准》表4中的一级要求.
