摘要
本文综述了当前废水BOD(生化需氧量)测量方法的特点及存在的问题,针对目前在线实时测量BOD困难的问题,提出应用近红外光谱仪及光纤来构架测量BOD的在线实时系统的解决方案,并对该方案存在的问题及应解决的问题作了说明。
Several traditional methods that have been used widely to determine biochemical oxygen demand （BOD） are discussed, and several new methods are introduced in this paper. Currently, there are no rapid and accurate methods for measuring BOD. The main problems restricting the application of the real-time technology are high cost and technology inaccessibly. However, near-infi-ared spectroscopy has the potential of build-up a real-time system for measuring BOD. A scenario of real-time, online BOD measuring system based on the technology of near-infrared spectroscopy and optical fiber are presented, and some difficult problems need to be solved are indicated.
