[0002] The protection of water resources is one of the important strategies to maintain the sustainable development of society. Scale inhibitors are essential drugs in the operation of circulating water systems. At present, the scale inhibitors in domestic industrial sites are manually configured without weighing or measuring during the configuration process, resulting in unstable content of scale inhibitors in circulating water, causing scaling, corrosion and excessive emissions in the circulating water system. There are safety hazards in the process of manually configuring scale inhibitors. In view of this, there is a need for an intelligent scale inhibitor dispensing device and method. Summary of the invention
