Working principle of sewage online monitoring system

In the water pollution prevention and control industry, the sewage online monitoring system plays the role of early warning of pollution and real-time monitoring of persistent pollutants. It has the ability to work continuously and provides accurate monitoring data for staff to analyze. These functions are all provided by the working principle adopted by the sewage online monitoring system. The working principle of the sewage online monitoring system The sewage online detector realizes the online monitoring of water quality through the particle selective electrode measurement method. The electrodes it uses are: pH, fluorine, sodium, potassium, calcium, magnesium and reference electrodes. There is an ion-selective membrane in each electrode, which reacts with the corresponding particles in the water quality sample. The membrane belongs to the ion exchanger, and changes the membrane potential after reacting with the ion charge. At this time, it can be used for liquid membrane potential detection. The ion concentration difference between the electrode solution and the sample in the interior generates an electrochemical voltage on both sides of the working electrode. The voltage is led to the amplifier through the high-conductivity internal electrode, and the reference electrode is also led to the amplifier. At this time, a standard curve can be obtained by detecting a standard with known particle concentration, so as to detect the particle concentration in the sample water quality. When the ions in the solution contact the electrode, an ion transfer reaction occurs inside the water layer of the ion selective electrode, causing the potential to change. The working principle of the sewage online monitoring system is different from other water quality monitoring systems. Before using this equipment, we should have a familiar understanding of it. Only in this way can we have a good understanding of the water quality when using the sewage online monitoring system. It has a good monitoring effect, and it is equipped with a variety of devices, so that it has a variety of water quality monitoring functions.
