采用氧化石墨烯(GO)、铁粉(Fe-Fe3O4)和二氧化铅(PbO2)制备合成多晶催化剂,利用水溶性纸(WSP)辅助催化剂负载导电基表面,通过相转化法制备具有高催化活性和高电导性的WSP多晶催化复合膜,并将其用作微生物燃料电池-膜生物反应器耦合系统(MFC-MBR)阴极电极膜,开展含铜/镍重金属废水电还原强化处理性能研究.实验结果表明,相比对照组,WSP多晶催化复合膜具有低还原电位及低欧姆电阻特性(还原电位和内阻仅为0.12 V和1.38 Ω);形态学表征证实,膜面负载催化剂均匀,高活性催化界面有利于重金属电还原过程.WSP多晶催化复合膜辅助MFC-MBR系统开展废水处理,Cu(Ⅱ)去除效率高于90％,Ni(Ⅱ)去除率在99％以上;铜镍混合废水中Cu(Ⅱ)、Ni(Ⅱ)同步去除率分别达到97.63％、93.18％.本研究表明,采用WSP多晶催化复合膜辅助MFC-MBR 耦合系统处理重金属废水,可实现重金属电还原强化脱除,具有高效率低运行成本优势,工程应用前景广阔.
Performance of WSP Polycrystalline Catalytic Composite Membrane for Enhanced Treatment of Heavy Metal Wastewater by Electroreduction
Graphene Oxide(GO),Iron Powder(Fe-Fe3O4)and lead dioxide(PbO2)are used to prepare poly-crystalline catalysts.Catalyst is effectively supported on the surface of conductive substrate based by the auxiliary of water-soluble paper(WSP).WSP polycrystalline catalytic composite membrane with high catalytic activity and high conductivity is prepared by phase inversion method.The prepared functional membrane is used as the cathode membrane electrode of the combined system of microbial fuel cell and membrane bioreactor(MFC-MBR),which is applied to carry out the study on the performance of enhanced electroreduction treatment of heavy metal wastewater containing copper/nickel.Compared with the control group,the experimental results show that WSP polycrystalline catalytic composite membrane has the characteristics of low reduction potential and low ohmic resistance(reduction potential and internal resistance only 0.12 V and 1.38 Ω).Morphological characterization illustrates that the cata-lyst loaded on the membrane surface is uniform,and the highly active catalytic interface is conducive to the elec-troreduction of heavy metals.WSP polycrystalline catalytic composite membrane assists MFC-MBR to carry out wastewater treatment.The removal efficiency of Cu(Ⅱ)is higher than 90％and that of Ni(Ⅱ)is more than 99％.The simultaneous removal efficiencies of Cu(Ⅱ)and Ni(Ⅱ)in copper/nickel mixed wastewater are 97.63％and 93.18％respectively.The research results indicate that,applying WSP polycrystalline catalytic com-posite membrane assisted MFC-MBR coupling system to treat heavy metal wastewater can achieve significant advan-tages,such as high removal efficiency of characteristic pollutants and low operating costs,and has broad engineer-ing application prospects.
