摘　　要：生化需氧量是指在规定条件下,微生物分解存在水中的某些可氧化的物质,特别是有机物所进行的生物化学过程中消耗溶解氧的量。目前对水体中的生化需氧量的测定除采用经典的稀释接种法外,已开始采用新方法,即微生物电极法。他能够在几分钟内测定水体的BOD含量,大大缩短了传统方法的五天培养时间,对于快速了解水体的有机污染状况,具有积极地的意义。Biological Oxygen Demand （ BOD5 ） is defined as the amount of dissolved oxygen used by the aerobic microorganisms in a sample at 20℃ in the dark for a five -day period. The short -time BOD under evaluation in this exercise is intended as a miniaturized, easier and much faster method to measure the equivalent of theBOD5. The short - time BOD measuring system is more easy and faster. The result for the user of this unique measuring principle is the precise and fully continuous determination of the BOD in three to four minutes.
