In order to make the aforementioned objects, features and advantages of the present invention more clearly understood, the present invention will be described in further detail with reference to the accompanying drawings and detailed description. It should be noted that the embodiments and features of the embodiments of the present application may be combined with each other without conflict.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced in other ways than those specifically described herein, and therefore the scope of the present invention is not limited by the specific embodiments disclosed below.

As shown in fig. 1, a purified water preparation system includes: a raw water treatment device, an intermediate treatment device, a pure water treatment device and a sterilization device which are connected in sequence through pipelines; the raw water treatment device comprises a raw water tank 1, a raw pump 2, a mechanical filter, an activated carbon filter 4, a positive resin softener 5 and a cartridge filter 6 which are sequentially connected through pipelines; the intermediate treatment device comprises a primary high-pressure pump 7, a primary reverse osmosis device 8, an intermediate water tank 9, a secondary high-pressure pump 10, a secondary reverse osmosis device 11 and a pure water tank 12 which are sequentially connected through pipelines; the pure water treatment device comprises a pure water pump 13, an EDI device 14 and a pure water tank 15 which are sequentially connected through pipelines, and the sterilizing device comprises a pure water pump 16, an ultraviolet sterilizing device 17, a precise filter 18 and a pure water consumption point 19 which are sequentially connected through pipelines.

The original water tank 1 is a stainless steel water storage tank which is made of anti-pollution and ageing-resistant materials, and the original pump 2 is arranged for ensuring the flow and the pressure of the water supplied by the system to be constant. The mechanical filter is a quartz sand filter 3 and is mainly used for removing suspended matters, silt and granular impurities in water and reducing turbidity in the water. The activated carbon filter 4 has very high removal rate for free chlorine, organic matters, chromaticity and smell in water and high removal rate for some heavy metal ions easy to deposit, the activated carbon filter 4 can play a very good protection role for reverse osmosis equipment when an intermediate treatment device is used, the cation resin softener 5 is used for improving the recovery rate of a Reverse Osmosis (RO) device and preventing carbonate, sulfate and other forms of chemical scaling from occurring on the concentrated water side of a reverse osmosis membrane concentrated water end (particularly the last group of membrane elements in a reverse osmosis pressure container), so that the performance of the membrane elements is influenced, and necessary scale inhibition treatment is carried out on the inlet water before reverse osmosis treatment. Na + contained in the resin in the softener tank exchanges with Ca2+, Mg2+, Fe2+ and the like in water, so that the content of Ca2+ and Mg2+ ions in the water discharged from the softener tank is reduced, and hard water is softened. Over time the resin in the softener exchanges to reach its exchange capacity, at which point the resin needs to be regenerated. The NaCl is added for salt absorption and regeneration, and the cartridge filter 6 is used as a filter element to prevent partial particles from being brought into reverse osmosis so as to ensure the quality of reverse osmosis effluent.

The first-stage high-pressure pump 7 feeds the water treated by the raw water treatment device into the first-stage reverse osmosis device 8, the first-stage reverse osmosis device 8 utilizes the property that a reverse osmosis membrane selectively can only permeate a solvent (usually water) to intercept ionic substances, and the membrane process of separating a liquid mixture is realized by overcoming the osmotic pressure of the solvent through the reverse osmosis membrane by taking the static pressure difference at two sides of the membrane as a driving force. The membrane separation method is adopted to remove harmful substances such as particles, colloid, organic impurities, microorganisms and the like and most dissolved salts in water, thereby achieving the aim of desalting and purifying water; the desalted water enters an intermediate water tank 9 and then enters a secondary reverse osmosis device 11 through a secondary high-pressure pump 10 (the main part of the secondary reverse osmosis device 11 is an RO membrane element, and the company selects an R0 series produced by American Heiden company or American Dow company, which has larger rated water yield, higher desalination rate and larger use allowance, and can still reach the designed water yield after ensuring the use effect, and the desalting device has the characteristics, and also has the advantages of pollution resistance and better Na + removal function), a dosing device 20 is arranged between the intermediate water tank 9 and the secondary high-pressure pump 10, and the dosing device 20 sets a dosing box for adjusting the pH value of the water; the second-stage reverse osmosis device 11 traps ion substances for the second time, removes salt for the second time, improves the water quality again, and flows into the pure water tank 12 after purification.

The pure water pump 13 sends water into the EDI device 14, the high-purity water after the EDI device treatment enters the high-purity water tank 15, the EDI device 14 mainly removes ions from the water treated by Reverse Osmosis (RO) and other purification equipment, and is an electric desalting technology, which integrates the electrodialysis technology and the ion exchange technology, realizes the directional migration of ions in the water under the action of an electric field through the selective permeation of cation and anion membranes to cations and anions and the exchange of ion exchange resin to ions in the water, thereby achieving the deep purification and desalting of the water, and the third desalting ensures that the water quality reaches the medicinal standard.

The high-purity water pump 16 enters the ultraviolet sterilization device 17 from the high-purity water tank 15 through physical desalination and electric desalination, and then is sent to the water consumption point 19 of pure water through the precision filter 18 for use, the ultraviolet radiation of the ultraviolet sterilization device 17 kills various bacteria and viruses in the water, and can effectively prevent the purified water from suffering from secondary microorganism pollution so as to ensure that the produced water is qualified, and the precision filter 18 is used as a filter element to prevent killed bacteria or possibly polluted particulate matters in the water tank from entering a pipe network system.
