化学法和光学法在线水质分析仪表在突发污染事件中的性能比较

Comparison of Performances of Chemical and Optical On-line Water Quality Analyzers in Sudden Pollution Events

摘要:

快速有效地识别突发水体污染事件是在线水质监测技术研发的重要内容。在构建包含实时响应性、测量准确性、可识别性、可校正性、可适应性、可扩展性六个维度的在线水质分析仪表性能指标体系的基础上，系统分析评估了突发水体污染事件下化学法和光学法在线水质分析仪表的性能。结果表明，在应对突发水体污染事件时，化学法与光学法仪表在测量精度方面均存在一定不足，但在实时响应性、可识别性、可校正性、可适应性、可扩展性等方面，化学法仪表的性能表现一般，而光学法仪表则具有较好的性能表现。

Abstract:

The rapid and effective identification of sudden water pollution events is the important content in the research and development of on-line water quality monitoring technologies. Based on the construction of an online water quality analysis instrument performance index system that includes six dimensions of real-time responsiveness, measurement accuracy, identifiability, correctability, adaptability and scalability, the performances of chemical and optical online water quality analyzers in response to sudden water pollution events are systematically analyzed and evaluated. The results show that in response to the sudden water pollution events, both chemical and optical instruments have certain deficiencies in measurement accuracy, but in terms of real-time responsiveness, identifiability, correctability, adaptability and scalability, the chemical instrumentation performance is average, while the optical instrumentation has a better performance.
