生化需氧量快速测定法的样品预处理

Preparing Samples for Speedy Testing of Biochemical Oxygen Demand

随着生物传感器技术的发展,现在我们可以采用固定化微生物传感器的方法来测定水质的BOD。该方法较之经典的五日稀释接种法省时省力。文章讨论了实验操作中的一些问题,得到了有实用价值的经验。

The biochemical oxygen demand, called BOD, is an important target to indicate water quality characteristic and the efficiency of wastewater treatment construction. Along with the biosensor technology development, now we can use the fixed microorganism sensor to determine BOD of water quality. Comparing with the classics approach of dilution and seeding （after five days）, the method is more convenient and efficient. This article discussed the experiment to operate some questions, obtaining experience of practical value.
