摘要
基于紫外-可见吸收光谱分析技术的水质测量仪器,具备在线、连续、实时的测量能力,在现场或野外进行水质在线监测时,直接沉入待测水体的不同深度,快速识别硝酸盐、亚硝酸盐和大部分有机污染物,获得连续、实时的水质数据,并能对多种水质参数进行同时测量分析,具有速度快、无污染、重复性好、精度高、维护量少等优点。在河流、湖泊、饮用水水源地等处的水质预警预报系统中加以应用,可以成为水质污染事故早期预警预报的有效工具。
It is necessary and important for us to obtain water quality parameters and their variation tendency rapidly, reliably and in time in water quality monitoring. The water quality monitoring instrument based on UV-vis absorption spectroscopy is able to measure water quality online, continuously and real-time. During field survey of online water quality, the instrument can identify nitrate, nitrite and most of the organic pollutants rapidly, offer continuous and real-time water quality data, and measure and analyze different parameters simultaneously when the instrument is placed in different depthes of water. With the advantages of rapidness, no pollution, fine repeatability, high precise and maintenance-free, the instrument is suitable for water quality early-warning and forecasting system and it would efficient in the early-warning and forecast of the pollution accidents in rivers, lakes and water supply areas.
