The purified water/water for injection combined distribution system is a kind of equipment integration device, which can fully convert and utilize resources and energy, greatly reduce production costs, save equipment floor space, and reduce equipment investment costs. At the same time, it can integrate the operation control system of the equipment, and the flow picture of the equipment can be freely switched and selected on the same operation interface.
