Water is the earth's most precious resource, and the management of water resources is crucial to sustaining the development of society. The rapid industrial development and dense population of industrial cities have caused serious pollution of the only river water. Therefore, efficient, energy-saving and environmentally friendly water treatment is an important guarantee for the harmonious development of China's economy, society and environment.

Water treatment solutions:

Water purification and sewage treatment power distribution control scheme: The developed smart box transformer adopts a new intelligent comprehensive control and protection unit to centrally transmit sub-station data in real time, which is stable and reliable and has high fault protection capabilities; secondly, the sub-station smart box transformer The intelligent control unit can independently undertake the basic control tasks of the control zone, communicate through the wired network, and send all data information to the water plant dispatching room for processing, or send part of the data through the dispatching system through wireless (or wired) communication. to the city's dispatch center.

Drainage system power distribution control scheme: The developed pump station control system supporting the smart box-type transformer provides a comprehensive data collection and control scheme for the city's water supply and drainage system. It has reliable, practical and convenient application software to reduce the user's daily maintenance workload. , ensuring the safe operation of the water supply and drainage system. The use of this system is conducive to improving the labor productivity of urban drainage pump station dispatching operators, allowing them to devote more time and energy to the reliable and economical operation of the pump station.
