At the present various deficiencies of producing deep purifying water method, through the practice that studies for a long period of time, the invention provides and a kind of tap water is being carried out in the deep purifying process, not only can reach harmful all contaminations matter in the different quality of removing different areas, and can add an amount of trace element to the human body beneficial, changing or increase some function of water, is a kind of new drink water production method.This method is applicable to the equipment and the device of all production drink waters.

The present invention adopts following technology to realize:

Tap water → pre-treatment → adsorption filtration → mineral substance adjusting → functionalization → terminal process → finished product drink water

In actual production process, at first carry out pre-treatment, so that except that heavy metal and the precipitable ions of part such as the suspended substance in anhydrating, microorganism, colloid thing, dissolved organic matter, ferrimanganics according to the different situations of tap water.If when hardness is too high, can in preprocessing process, remove part hardness.The tap water pre-treatment should look the kind of impurity in the tap water and content adopts diverse ways, as: cohesion, oxidation, chlorination, softening, sedimentation and filtration etc.Should be able to satisfy aftertreatment device after the tap water pre-treatment and require the influent quality index.

Second step method that adopts absorption to decolour through pretreated water, deodorizing, removal chlorine residue and various organic pollutant.Generally should select methods such as granulated active carbon, active carbon loading silver, activated carbon fiber, diatomite, macroporous adsorbent resin, also can adopt the various combination of above-mentioned the whole bag of tricks according to different water quality situations and water production rate size.

The main purpose that the 3rd step mineral substance is regulated is suitably to remove mineral substance unnecessary in the water, removes harmful heavy metal and other harmful element.Generally can require to adopt ion-exchange, electrodialysis, ultrafiltration (or nanofiltration), reverse osmosis and at the extraordinary removal device of certain element (as defluorination, removing of iron and manganese, deleading, arsenic, mercury, cadmium, chromium and remove ammonia nitrogen etc.) according to concrete water inlet.

The 4th step was that water is carried out functionalization, so that increase the activity of water, add some mineral substance and other elements to the human body beneficial, strengthen promoting health and curing diseases function and other function of water, method commonly used has physical method (as electrolysis, magnetization, HF oscillation, far-infrared radiation etc. and various combination thereof), chemical process (add in right amount to the human body beneficial's and can improve aesthetic quality's element and material) and biological method (add an amount of biotechnological formulation, adopt different biological methods) etc. to the human body beneficial.

The purpose of the 5th step terminal process is further to increase water quality, and generally adopts the method for disinfection and secondary filter.Disinfection can adopt ultraviolet irradiation, ultrasonic sterilization, chlorination sterilization, oxidation sterilization and other medicines sterilization etc.; Secondary filter can be removed subparticle that the prime operation brings and other material etc., can select for use ultra-filtration membrane or millipore filtration to carry out according to the requirement of flooded condition and finished product water.

Advantage of the present utility model is: the production method of drink water has increased the functionalization process of mineral substance adjusting and water, is fit to the different quality in district variously, can produce the drink water that meets the healthy drinking water requirement.The mineral substance regulate process not only can reduce too much mineral substance, removes harmful mineral substance, reduces water hardness from the beginning, also can replenish mineral substance and trace element to the human body beneficial in right amount; The functionalization of water then can increase the activity of water according to the requirement to finished product water, changes or strengthen some original function of water, makes the finished product glassware for drinking water that health care and medical functions be arranged.
