氧化型锰矿石脱硫产物含大量硫化锰,利用这种材料装填固定床进行净化水中铜离子的动态试验。在材料粒径0.45～0.9mm、进水pH=5.8、进水滤速4.58m/h条件下,1t锰矿石脱硫产物可以处理923tρ(Cu2+)=50mg/L的含铜废水,出水ρ(Cu2+)<0.5mg/L,低于国家一级排放标准。控制进水pH在4～9之间、降低进水滤速、采用较小粒径的材料有利于提高锰矿石脱硫产物处理含铜废水的容量。利用X射线粉末衍射(XRD)和扫描电镜-能谱分析(SEM-EDS)对材料和产物进行表征,证明锰矿石脱硫产物去除水中铜离子是基于离子交换反应的原理。 Oxidized manganese ore desulfurization products containing a large amount of manganese sulfide, the use of this material packed fixed bed for purification of copper in water dynamic test. Under the condition of material particle size of 0.45-0.9mm, inlet water pH = 5.8 and water filtration rate of 4.58m / h, the 1t manganese ore desulfurization product could treat Cu2 + wastewater containing 923tp (Cu2 +) = 50mg / L, ) <0.5mg / L, lower than the national level emission standards. Control of influent pH between 4 and 9, reducing the influent filtration rate, the use of smaller particle size material is conducive to improving the manganese ore desulfurization capacity of copper-containing wastewater treatment capacity. The materials and products were characterized by X-ray powder diffraction (XRD) and scanning electron microscopy (SEM-EDS). The results showed that the removal of copper ions from the manganese ore desulfurization products was based on the principle of ion exchange reaction.
