摘　　要：生化需氧量(BOD)是一种表征水体有机污染程度的综合指标,广泛应用于水体监测和废水处理厂的运行控制中。由于BOD的标准测定方法需时5d,不能及时地反映水质状况和反馈处理信息,因此快速测定BOD的方法和仪器化研究近年来得到广泛的重视。其中利用生物传感器测定BOD是一种有效地快速测定废水中可生化降解有机物的方法。文章介绍了生物传感器的工作原理及其生物敏感材料,讨论了BOD快速测定值(BODst)与标准BOD5值的一致性问题。对目前市场上常见的几种BOD测定仪的性能进行了比较。Biochemical oxygen demand ( BOD) is a comprehensive indicator characterizing the degree of organic pollution of water body and wastewater and widely used in monitoring water body pollution and in measuring BOD removal efficiency of wastewater treatment systems. However, it will take 5 days to get the BOD value in standard method that cannot reflect the water pollution state and feedback the treatment information immediately. Therefore measurement of BOD using biosensor has received increasing attention in recent years. It is an effective method for BOD rapid analysis. The BOD biosensor can fast measure the concentration of biodegradable substrate in wastewater. The present development of BOD sensors is summarized based on plentiful paper in this field. Firstly, the measuring principles and sensor fabrication was briefly introduced, then the agreement between the sensor BOD value and BOD5 value was also covered. In order to give a complete picture of BOD biosensors, respirometer specially designed for BODst measurement and BOD biosensors based on other principles were also briefly introduced in a separate section. Finally, some commercial BOD instruments were described, and their performance was discussed.
