摘要:水质在线监测系统长期运行故障率会逐渐升高,接近使用年限时需加大维护频率,必要时还要进行系统升级改造。以上海市苏州河水质在线监测系统某测站改造为例,介绍水质在线监测系统的改造项目及在线仪器与实验室分析数据的比对过程。分析得知:系统改造后,在线监测仪器的pH氨氮、高锰酸盐指数3个指标与实验室数据基本一致,可以反映水体的水质情况。

Abstract: The failure rate of automatic online water quality monitoring system will increase with the operation time going by. When its key parts approach the end of service life, the system will become unstable. The solution lies in the increasing of maintenance frequency and the implementing of a full system upgrade. Taking a certain water quality monitoring station remolds of the Suzhou River online automatic water quality monitoring system in Shanghai as an example, the article introduces the composition process of the renovation project of on-line water quality monitoring system and on-line instrument and laboratory analysis data. Throughput analysis it can be concluded that after the system reformation, the indicators of pH, ammonia nitrogen and permanganate indexes from the online monitoring instruments are basically consistent with those acquired in the laboratory, and consequently reflect the authentic condition of the water quality.

Keywords: Water quality online Monitoring system; comparison experiment; relative deviation
