摘　　要：通过对比活性炭纤维-涂层RuO_(2)钛板、活性炭纤维-石墨板以及石墨板-涂层RuO_(2)钛板三种不同阴阳极组合体系产H_(2)O_(2)的能力。选取以活性炭纤维为阴极,涂层RuO_(2)钛板为阳极电解产H_(2)O_(2)体系为研究对象,考察了不同pH值、电解质(Na_(2)SO_(4))浓度和电流密度对产H_(2)O_(2)影响。结果表明,当pH=3、Na_(2)SO_(4)浓度为0.05 mol/L和电流密度6.79 mA/cm^(2),电解180 min时,体系产H_(2)O_(2)浓度可达403.04μmol/L。与此同时,以磁性氧化石墨烯(MGO)作为粒子电极,与活性炭纤维-涂层RuO_(2)钛板电解体系构建三维非均相电芬顿系统,在降解水中TC实验结果表明,该体系可对初始浓度为500 mg/LTC实现较好的去除效果,去除率达93.5%。The H_(2)O_(2) production capacity of three different cathode and anode combination systems,namely activated carbon fiber-coated RuO_(2) titanium plate,activated carbon fiber-graphite plate and graphite plate-coated RuO_(2) titanium plate,was compared.The production of H_(2)O_(2) system activated carbon fiber as cathode and coated RuO_(2) titanium plate as anode was selected as the research object,and the effects of different pH values,electrolyte(Na_(2)SO_(4))concentration and current density on H_(2)O_(2) concentration were investigated.The results indicated that the highest concentration of H_(2)O_(2) produced by the system could reach 403.04μmol/L,when pH=3,Na_(2)SO_(4) concentration of 0.05 mol/L,current density of 6.79 mA/cm^(2) and electrolysis time of 180 min.At the same time,a three-dimensional heterogeneous electro-fenton system was constructed with activated carbon fiber-coated RuO_(2) titanium plate electrolysis system and magnetic graphene oxide(MGO)which used as the particle electrode.The experiment results of TC degradation in water showed that the system could achieve a better removal effect for the initial concentration of 500 mg/L TC,and the removal rate could reach 93.5%.
