摘要
采用光谱信息融合理论,研制了一种新型便携式多参数水质分析仪,自行设计了仪器的分析方法、硬件结构、内部工作原理及软件功能。可作为一种无须化学试剂、体积小、快速、易于野外现场作业的绿色水质检测工具。通过对少量水质样品的光谱测量分析,快速检测了总有机碳(TOC)、化学需氧量(COD)等6类水质有机污染物指标。实际测量结果表明,本仪器采用的基于多源光谱信息融合的水质分析方法测量精度显著优于目前市场上普遍采用的常规紫外吸收光谱法。
A novel portable multi-parameter water quality analyzer was developed based on the multi-spectra information fusion theory.The analysis method,hardware structures,working principles and software functions are described in the present paper.As a small size,rapid testing and outdoor green instrument,this analyzer can be used to measure six water organic pollution indicators,including TOC,COD,etc.,through analyzing the spectra of a small amount of water sample without any chemical reagent.The practical water analysis experiments showed that the multi-spectra fusion method used by this analyzer possesses a higher measurement precision than that of the UV spectral analysis method,which is popularly used by the water quality analyzers in the market.
