摘要
生化需氧量(BOD)是判断水体受污染程度、指导污水处理工艺设计的重要指标。近年来基于微生物电化学技术开发的BOD传感器因能快速、准确地测定BOD而成为极具应用前景的方法。总结了微生物电化学BOD传感器的工作元件及其原理,并对不同类型的微生物电化学BOD传感器进行了对比;在此基础上重点分析了微生物燃料电池(MFC)型BOD传感器的发展历程、传感原理、反应器构型以及产品化应用;进一步讨论了各种新兴技术给MFC型BOD传感器带来的发展契机,提出了将其商品化的发展见解;最后对微生物电化学BOD传感器的发展进行了总结与展望,以期为开发快速高效的微生物电化学BOD传感器技术奠定基础,为推动水生态环境监测技术的创新发展提供思路。
Biochemical oxygen demand(BOD)is an important indicator to determine the degree of pollution of wa⁃ter and guide the design of wastewater treatment processes.In recent years,the development of BOD sensors based on microbial electrochemical technology has become a promising method for the rapid and accurate determination of BOD.This review summarized the working components and principles of microbial electrochemical BOD sensors,and compared different types of microbial electrochemical BOD sensors.On this basis,the development history,sensing principle,reactor configuration and product application of microbial fuel cell(MFC)-type BOD sensors are analyzed.Further,the development opportunities of MFC-type BOD sensors brought by various emerging technolo⁃gies were discussed,and the insight of commercialization was proposed.Finally,the development of electrochemical BOD microbial sensors was summarized and prospected,laying the foundation for the development of fast and effi⁃cient microbial electrochemical BOD sensor technology,and promoting the innovative development of water ecology and environment monitoring technology.
