[0001] This utility model belongs to the field of water treatment technology, and in particular relates to a direct drinking water treatment device that adopts a distributed water supply for centralized water purification. Background Technology

[0002] Existing direct drinking water treatment equipment still has obvious defects in treatment: when raw water is transported by a booster pump, air bubbles are easily generated in the pipeline, but there is no special discharge mechanism, which leads to a decrease in water transmission efficiency, an increase in equipment energy consumption, and a tendency to cause corrosion or air blockage; the filtration components are not fine enough, and the direct discharge of concentrated water causes waste of water resources and environmental burden; after the direct drinking water enters the temporary storage tank, there is a lack of downstream real-time water quality monitoring and secondary purification, making it difficult to deal with secondary pollution during the storage process and unable to guarantee the stability of the end water quality. Utility Model Content
