【摘要】 水质监测是用科学的方法监视和检测反映环境水质及其变化趋势的各种数据的过程 ,其核心内容是监测与分析评价水资源的质量状况及其变化规律 ,为国家和各级政府开发利用、管理与保护水资源提供科学依据。在我国 ,水体的有机污染是水质污染的主要问题 ,其中主要是工业废水和城市污水造成。因此 ,采用在线自动监测仪器对污染源进行自动监测 ,是治理越来越严重的环境污染的良好基础。本文通过对用于水质在线监测的COD、TOC、UV自动测量仪的工作原理、测试方法、性能特点等的比较研究 ,揭示三者之间的内在联系更多还原

【Abstract】 Water quality monitoring is a process of surveilling and inspecting data which can reveal the environmental water quality and its change trend by scientific methods Its core content is providing scientific basis to the government for utilizing, management and protection of water sources by monitoring and analyzing its quality status and changing rules The main question of water pollution is organic pollutants caused mostly by industrial effluents and municipal sewage in our country Therefore, how to monitor water sources by adopting auto-monitoring instruments is a key point This paper studies on the inherent relations between COD,TOC and UV auto-analyzers by comparing their working principles, testing methods, characteristics and so on According to our research, the UV analyzer can be used to inspect the degree of organic pollutants in sewage quickly and precisely Its cost is lower than COD or TOC analyzer更多还原
