Refined simply said is “accurate, refined, in-depth, standardized” comprehensive mode! In this chapter, water quality online monitoring instrument manufacturers will work with you to understand the application of fine water quality monitoring.
The work of sewage monitoring, as early as more than 20 years ago has been implemented, the work of water quality testing has the protection and management of water resources, the construction of water conservancy projects, etc., because of various reasons, there are some problems in the process of water quality monitoring that need to be solved.
We know that most of the water pollution is caused by organic pollution, in the actual monitoring process, it is necessary to adjust the monitoring indicators according to its actual situation. In the existing monitoring index system, organic indicators are regarded as comprehensive monitoring items, so it is difficult to show pollution in an objective way in different situations. However, the water quality monitoring instrument is not targeted at water quality inspection, and it is easy to repeat monitoring or repeated monitoring of the part with relatively low pollution degree.
In the process of water quality monitoring, we can use a variety of technologies, which can be divided into conventional monitoring and unconventional monitoring technologies.
· Conventional monitoring technology mainly refers to physical and chemical monitoring. The operating instruments used in physical and chemical testing of water quality are relatively simple, and the required monitoring data indicators are relatively easy to obtain. Some of the more full-featured monitors can measure multiple indicators at the same time. In the monitoring of inorganic water pollutants, the technology used in the beginning was photometry, and then gradually developed into atomic absorption method, and added the analysis of morphology and valence state.
· Unconventional monitoring technologies mainly include two kinds, namely automatic water quality monitoring and biological monitoring technology. The technology of automatic water quality monitoring is relatively perfect, and it is the advanced stage of monitoring water environment. If a perfect automatic water quality monitoring system can be established, it can realize long-term continuous monitoring of the water environment in the local area, such as reservoirs and lakes. In the process of continuous monitoring, the water quality status and the change law of water quality can be monitored in real time, so that pollution events within the monitoring range can be found in time and relevant reports can be made. Analyze the real-time monitoring data, make regular monitoring reports, and establish the general trend of water quality changes according to the data changes, so as to be able to predict the change of water quality.
