It is crucial to measure the conductivity value of water quality. It can not only reflect the total dissolved solids in the water body, but also be used for drinking water, industrial production, environmental monitoring and agricultural irrigation. Therefore, for the monitoring and control of water quality, the conductivity value is a parameter that must be paid attention to. Monitoring the conductivity value of sewage can provide information about the concentration of dissolved ions in sewage. Conductivity refers to the resistance encountered when electric current passes through a conductor per unit length and cross-sectional area. Therefore, the higher the concentration of dissolved ions in sewage, the higher its conductivity. By monitoring the conductivity value of sewage, the ion concentration in sewage can be quickly and easily evaluated. This evaluation can help us determine the type and concentration of pollutants in sewage, so as to determine the treatment measures that need to be taken. In addition, monitoring the conductivity value of sewage can also help us understand the operation of the sewage treatment system and whether maintenance and repair are needed.
