摘　　要：本文主要研究基于UV法的COD在线监测技术,在线监测技术包括集成数据采集、量程切换、输入输出为一体的嵌入式硬件控制部分和软件操作部分。嵌入式硬件控制部分通过定时采集水样的两种吸光度,并自动选择合适通道传输给上位机进行处理;软件操作部分是系统操作的核心,通过设置各种参数,用户可以测定、读取、换算出COD值。This paper mainly studies COD on-line monitoring technology based on UV method, it includs integrated switch range, input and output of data acquisition, embedded hardware control parts and software operation. Embedded hardware control part by regularly collecting water samples of two kinds of absorbance, automatically chooses the right channel to the PC for processing. Software operating part is the core of the system operation, by setting the parameters, the user can determine, read, conversion of COD value.
