At present, the hospital realizes the compatible production and the supply of soft water and pure water through soft water pure water treatment facilities, wherein carries out the prefilter to the running water through soft water processing system and obtains the soft water, carries out once more by the reverse osmosis unit to the soft water and obtains the one-level pure water, recycles the reverse osmosis unit and filters the one-level pure water once more and obtain the second grade pure water, then carries soft water, one-level pure water and second grade pure water respectively to the use place that corresponds in order to supply to use. Although the production of soft water, primary pure water and secondary pure water can be produced by using the existing soft water pure water treatment apparatus, the following problems exist in the production process:
1. insufficient supply of soft water: although the existing pure water equipment is attached with soft water production capacity, most of the produced soft water is used for pure water production, and only a small part of the produced soft water is used for cleaning instruments, so that the supply of the soft water is insufficient;
2. the existing pure water equipment does not have an emergency water supply plan: on one hand, because the pure water equipment needs to be subjected to maintenance work such as online cleaning after being used for a period of time, taking the pure water equipment with the capacity of 1000L/h as an example, when the pure water equipment is subjected to online cleaning, several hours are consumed, soft water and pure water cannot be generated in the period of time, and a hospital often washes equipment for twenty-four hours and consumes the soft water, so that the supply of the soft water in the period of online cleaning of the pure water equipment is insufficient; on the other hand, if the water softening equipment fails, softened water and pure water may not be produced, which may seriously affect the working quality and efficiency of the disinfection supply center;
3. the waste of water resources is big: the existing water softening equipment can also produce concentrated water in the process of producing pure water, and the existing water softening equipment basically directly discharges the concentrated water as waste water, thereby causing a great deal of water resource waste.
