水质监测是环境监测的一个重要组成部分,也是现代环境污染处理、环境质量评价和管理的基础工作。长期以来,传统的定时人工采样,不能及时地发现偶然事件所引起的水质变化。由于,水质监测的复杂性,使水质监测自动化比大气自动监测、水文自动监测要困难得多,特别是自动监测系统的传感器因被污染,而严重地影响了监测数据的准确性和可靠性。目前,我国水质自动监测工作刚刚开始,对水质传感器的研究还比较落后。自1989年以来,淮河水质监测中心经多方面的调查和可行
Water quality monitoring is an important part of environmental monitoring, but also the basic work of modern environmental pollution treatment, environmental quality assessment and management. For a long time, the traditional time-based manual sampling, can not be found in time caused by changes in water quality. Because of the complexity of water quality monitoring, automation of water quality monitoring is more difficult than automatic monitoring of the atmosphere and automatic monitoring of hydrology. In particular, the sensors of automatic monitoring system are seriously contaminated and seriously affect the accuracy and reliability of monitoring data. At present, the automatic monitoring of water quality in our country has just begun, and the research on water quality sensors is still relatively backward. Since 1989, Huaihe River Water Quality Monitoring Center has been investigated in many ways and feasible
