摘　　要：为在处理高含量萘的同时获得电能,实现污染物的降解与能源化,采用碳纳米管(CNT)/纤铁矿(γ-FeOOH)阴极微生物燃料电池生物电芬顿法对水中高含量萘的降解效果及产电性能进行研究,同时探索阴阳两极最佳加药(质量浓度100 mg/L萘溶液)顺序对萘降解效果的影响。结果表明,先阳极后阴极的加药顺序在反应55 h后萘的降解率达到100%,而先阴极后阳极的加药顺序在较短的反应时间(48 h)内获得100%去除率,因此先阴极后阳极的加药方法对于未来高含量萘废水的处理具有重要意义。In order to obtain the electrical energy while treating high content of naphthalene,and realize degradation and energy conversion of pollutants,electro-Fenton process by microbial fuel cells with carbon nanotube(CNT)/lepidocrocite(γ-FeOOH) cathode for high content of naphthalene treatment was studied.The effect of the best order of dosing in anode and cathode(mass concentration of naphthalene was 100 mg/L) on naphthalene degradation efficiency was explored.The results showed that,adding naphthalene solution in anode first and then in cathode,the naphthalene degradation rate reached 100% after 55 h reaction,but adding naphthalene solution in cathode first and then in anode took less time(48 h) to obtain 100% removal rate of naphthalene.Therefore,the order of dosing in cathode first and then in anode has an important significance for high-content naphthalene wastewater treatment.
