【摘要】 对铁氧体与锰共沉淀进行了中和法和氧化法两种方法的试验研究,并探讨了主要技术参数。结果表明,模拟废水中Mn2+含量在110 mg/L~310 mg/L时,常温下,Fe3+/Fe2+(质量比)=2,投料比Fe2+/Mn2+(质量比)=4,pH=10的条件下(氧化法中曝气时间t=6 m in),Mn2+的去除率可达99%以上,出水水质达到国家工业废水的排放标准。更多还原

【Abstract】 The conditions of treating wastewater containing manganese with ferrite process were studied between neutralization and oxygenation.The two methods have a high capacity of removing manganese under the conditions of 110 mg/L³10 mg/L of manganese,Fe²⁺/Mn²⁺（the mass ratio）=4,Fe³+/Fe²⁺（the mass ratio）=2,t=25 ℃,pH=10.The removal efficiency of Mn²⁺ is up to above 99%.The concentration of manganese in treated wastewater was below the drainaged standard.更多还原
