Energy-saving water-saving safe-water-quality medical reverse-osmosis pure water system

Abstract

The invention discloses an energy-saving water-saving safe-water-quality medical reverse-osmosis pure water system which comprises a primary reverse-osmosis pure water device provided with a water inlet, a pure water outlet and a concentrated water outlet, wherein the water inlet is connected with a high-pressure pump; the concentrated water outlet is connected with a concentrated water recovery device; the concentrated water recovery device comprises a shell and a filtering membrane arranged in the shell; the shell is provided with a recovery water outlet and a wastewater outlet; and the recovery water outlet is connected with the inlet of the high-pressure pump through a pipeline. The energy-saving water-saving safe-water-quality medical reverse-osmosis pure water system can treat the concentrated water, which can only be discharged as wastewater, into a high-quality influent water source for the primary-reverse osmosis pure water device by using the surplus pressure of the concentrated water; and concentrated water is subjected to one-step primary reverse-osmosis treatment to obtain the medical pure water with stable and reliable quality. The system has the advantages of low energy consumption and lower tap water consumption, obviously lowers the medical wastewater treatment cost, and has obvious economic and social benefits.

Description

technical field [0001] The invention relates to the field of membrane water treatment in hospitals, pharmaceuticals, food processing, drinking water, etc., which have high requirements on water quality and safety, and in particular to a medical reverse osmosis pure water system with energy saving, water saving and water quality safety. Background technique [0002] With the continuous improvement of my country's medical security system and the full implementation of rural medical insurance, the number of newly built and expanded hospitals has increased significantly, and new water treatment equipment is urgently needed. As a new type of medical water treatment equipment, the hospital central pure water supply system is an important construction project for new hospitals in recent years. In some earlier hospitals, the design of the pure water system was unreasonable, the equipment quality was not up to standard, the water delivery pipeline was not standardized, there was a lo...

AI Technical Summary

Problems solved by technology

Therefore, the use of this filtered water is likely to cause salt corrosion and microbial contamination of stainless steel pure water pipelines, which has medical safety risks

Even with low-pressure reverse osmosis or nanofiltration treated recycled water, its pollutant content is several times that of normal pure water, which will significantly reduce the biological safety of medical water

Therefore, it is not advisable to meet the conductivity index of some medical water as the standard, and mix the reverse osmosis concentrated water into the first-grade reverse osmosis pure water or directly use it as medical flushing water for operating rooms, obstetrics, and stomatology.

[0004] At present, the medical central pure water system has a relatively consistent overall design scheme in the industry, and the failure rate of the equipment has been significantly reduced. This part of the produced water with poor water quality meets the requirements of medical water, and can maintain water quality safety for a long time in the long-distance pipeline transportation system. This technical problem has not been solved.
