The utility model relates to an intelligent pure water/ultrapure water preparation system which comprises the steps of pretreatment of water, medicine addition, membrane filtration, sterilization and disinfection. The intelligent pure water/ultrapure water preparation system is characterized in that the whole flow from the original inlet water to the pure water product adopts module design; a pretreatment module, a constant temperature module, a reverse osmosis primary desalting module, an EDI deep desalting module, a physical sterilizing module, a TOC decomposition module, a desaeration module, a temperature regulating module and a water quality precision processing module are connected in series sequentially to form the whole process flow; and the operations of the modules in the flow adopt a distributed automatic control system and utilizes the fieldbus to realize three-step control of centralized management and decentralized control on the working conditions of the modules of the process flow of the syste
