摘　　要：为高效降解盐酸四环素(TCH)废水,以活性炭为原料,制备了多通道活性炭基导电炭膜(ECM)。采用扫描电子显微镜(SEM)、X射线衍射仪(XRD)、拉曼光谱仪(Raman)等技术对ECM的形貌与结构进行表征;采用循环伏安性能测试(CV)、电化学阻抗谱测试(ELS)等表征手段分析了导电炭膜的电化学活性,并采用ECM膜电极材料设计构建新型的电催化膜反应器(ECMR),研究ECMR催化降解TCH的性能。结果表明:所制备的ECM具有发达的孔隙结构和较好的机械强度与导电性,孔隙率为43.2%、抗折强度为14.3 MPa、电导率为6275 S/m;在外加电压为2.5 V、TCH质量浓度为50 mg/L、停留时间为5 min的条件下,ECM对TCH的去除率为85%,对总有机碳(TOC)的去除率为72%,且经10次循环使用后其降解性能基本保持稳定,表明ECM是良好的导电膜材料,在处理抗生素废水领域中展现出了巨大潜力。For efficient degradation of tetracycline hydrochloride(TCH)wastewater,a multi-channel activated carbon based conductive carbon membranes(ECM)were prepared from activated carbon.The morphology and structure of ECM were characterized using scanning electron microscopy(SEM),X-ray diffraction(XRD),Raman spectroscopy,and other techniques.The electrochemical activity of the conductive carbon membrane was analyzed using characterization methods such as cyclic voltammetry(CV)and electrochemical impedance spectroscopy(ELS),etc.The ECM membrane electrode materials were also used to design and construct a novel electrocatalytic membrane reactor(ECMR),and the performance of ECMR in the catalytic degradation of tetracycline hydrochloride(TCH)was investigated.The results show that the prepared multi-channel activated carbon based conductive carbon membrane has a porosity of 43.2%,a flexural strength of 14.3 MPa and an electrical conductivity of 6275 S/m.It has a well-developed pore structure and good mechanical strength and electrical conductivity.In addition,under the conditions of applied voltage of 2.5 V,TCH concentration of 50 mg/L and residence time of 5 min,the removal rate of TCH by ECM is 85%and the removal rate of total organic carbon(TOC)is 72%.These results show that ECM is a good conductive membrane material and has shown great potential in the field of treating antibiotic wastewater.
