微量污染物应急及在线监测技术在珠江流域水源地的应用

Application of Micro-pollutants Emergency and On-line Monitoring Technology in Water Source of Pearl River

法国AQUAPOD Light分析仪和AQUAPOD case应急监测仪用于微量有毒有机物和常规水质参数的在线监测,可对未知有机污染物发出报警,是实用性很强的微量污染物在线监测技术手段。基于该系统已建立了17个珠江流域特征有毒污染物的在线监测模型,将其应用于珠江重点饮用水源地,并对数据模型进行了检验;系统还具备常规参数的监测能力,其对COD、TOC和硝酸盐类等污染物监测的数据经与实验室内测试结果相比较,数据误差分布的检验结果表明其准确度和精密度均较好。

Using UV technology, AquaPod Light and AquaPod case emergency instrument can monitor some normal and micro pollutants water quality parameters. As a good practicability technology, it can give alarm when some unknown pollutants are found. There are 17 pollutants monitoring models were built for the Pearl River Basin, and a real-time monitoring station was constructed in the water source of Zhuhai City. This system can monitor COD, TOC and nitrate. The eonelusion indicates that the data deviation between the emergency and laboratory instru- ment have good uniformity.
