[0002] During the operation of a thermal power plant, the ultrafiltration system is a critical component of the boiler feed water treatment system. Its primary function is to filter and purify pre-treated raw water to remove suspended solids, colloids, microorganisms, and macromolecular organic matter, thereby meeting the boiler feed water quality requirements for subsequent treatment processes. However, during the operation of the ultrafiltration system, a certain amount of produced water is consumed for backwashing, and this water is referred to as "self-use water." Currently, thermal power plants rely on manual statistics and simple manual estimates to calculate the self-use water rate and water consumption of the ultrafiltration system, which suffers from low efficiency and large errors. Therefore, a highly automated and accurate system and method are needed to address these issues. Summary of the Invention
