摘　　要：生物化学需氧量(BOD)是目前国际上用来衡量水质有机物污染的重要指标之一。由于水体中氧的溶解度非常低,以电子媒介体代替溶解氧为电子受体的介体型BOD生物电化学传感器以其快速、准确、稳定等优点得到了较快的发展。论述了介体型水质BOD生物电化学传感器的发展现状及研究动态,重点讨论了介体型水质BOD生物电化学传感器的工作原理、构成及类型,分析了不同类型传感器的优缺点,并对其核心部分-微生物膜的制备方法做了比较详细的介绍。Biochemical Oxygen Demand （BOD） is one of the most important parameters in the measurement of biodegradable organic compounds and pollutants in water. Due to the low solubility, the mediator-type BOD bioelectrochemical sensor with redox electron mediator as electron acceptor has a rapid development compared with the conventional oxygen-based BOD bioelectrochemical sensor for its advantages, such as fast response , high accuracy and stability. In this paper, the development status and research trends of the mediator-type BOD bioelectrochemical sensor are reviewed. The working principle, composition and classification are discussed emphatically, and the merits and demerits are analyzed. In addition, the preparation methods of microbial biofilms are introduced in detail as the key point of the sensors.
