Implementation process:
1, tap water is through front two-stage preprocessing filter element, large granular impurity and the chlorine residue etc. such as filtering silt particle, iron rust, algae.
2, water enters film bodyguard (KDF filtrate carries out except divalent salts, demineralized water, and anti-bacteria, except chlorine residue) through front two-stage pre-treatment.
3, the water of third stage preprocessing filter element to prime purifies further, ensures the influent quality of RO film.
4, the pretreated water of the third stage can provide as domestic water, meet wash dish, wash one's face and rinse one's mouth, sanitation and hygiene etc.
5, topping-up pump carries out supercharging to water, allows hydraulic pressure reach the operating pressure of RO film.
6, temperature steady flow process: three grades, water source preprocessing filter element; enter heating component 84; temp probe 87 before film responds to inflow temperature; when film inflow temperature is less than 10 DEG C, control heating component 84 by intelligent controller and start, by constant for water temperature before film at 25-30 DEG C; when water temperature over-high before film; control overheating protection pressure switch 83 by temperature probe 87, intelligent controller 16, micro pump 82 starts, and prevents water temperature over-high before film.Flow inductor 88 plays does current stabilization effect.
Reverse osmosis membrane is in former water water temperature lower than less than 10 DEG C, and water production rate obviously declines, thus causes water purification mechanism water overlong time, and even do not shut down, topping-up pump load increases, and affects film work-ing life.Therefore, thermostat generally can not run under normal conditions.
7, water enters RO film, utilizes reverse osmosis membrane separation technology to purify.
8, the pure water of former water after reverse osmosis module 7 filters, access back pressure regulator 107 and pressure pot 11, controlled the pressure at reverse osmosis module 7 back side by back pressure regulator 107, avoid pressure pot 11 pairs of reverse osmosis modules to form back pressure;
9, controlled the pressure at reverse osmosis module 7 back side by back pressure regulator 107, stablize the net water flux of reverse osmosis module 7, reduce the quantity discharged of dense water.
10, through the waste water of reverse osmosis membrane group 7, under the effect of topping-up pump 6, again return of waste water device 47 is passed through with the flow of 300ml/min.Mix with former water after the softening desalination of polishing resin through KDF filtrate, weaker concn, enter reverse osmosis membrane group 7 at a high speed, again filter purification.Because the glassware for drinking water entering reverse osmosis membrane group 7 has the feature of lower concentration and high flow rate, thus reduce the generation of concentration polarization in film, extend the work-ing life of film.
11, after reverse osmosis membrane group 7, wastewater outlet side is provided with smart water quality monitor 412, can respond to the concentration of waste water salt, feed back to smart valve 10.When concentration value reaches certain set(ting)value, smart valve 10 opens water route, carries out instantaneous discharge, thus reaches flushing reverse osmosis membrane group 7 surface, reduces the effect of salt concn.
13, because of the sofening treatment of the front water source of film through film bodyguard, most incrustation scale is removed, useless only than being reduced to trace waste water discharge by 2:1.Thus improve the rate of recovery of water, reduce discharge of wastewater.
Major technique ensures:
1, in the pretreatment system of reverse osmosis filter core, the device that one is filled with desalination soft water filtrate is increased.
2, polishing resin is mixed by hydro-strong acidic cation exchange resin and hydrogen-oxygen type strongly basic anion exchange resin.The filtration unit of anion and cation exchange resin mixed packing according to a certain percentage, anions and canons in water, negatively charged ion in resin layer water is replaced by hydroxide ion, positively charged ion in water is replaced by hydrogen ion, enter hydroxide ion in water and hydrogen ion forms water molecules, thus reach the effect of desalination.Resin anion(R.A) volume: resin cation (R.C.) volume=2:1, polishing resin is without the need to regeneration.
3, the effect of KDF treatment media to calcium carbonate scale has two aspects: according to pH value and the relation between gas concentration lwevel and dissolution of calcium carbonate degree, when carbonic acid gas removes from solution, pH value raises, thus the solubleness of calcium carbonate is made to reduce, KDF also makes the pH value of water raise by electrochemical reaction, reduce the solubleness of calcium carbonate, result makes calcium carbonate separate out; On the other hand, due to oozing out of zine ion in KDF, zinc ion content in water increases to some extent, in water, the existence of zine ion can change the crystal formation mechanism of incrustation scale, the calcium carbonate scale in water is made to produce precipitation with the crystal habit of aragonite, the wall of container forms soft dirt, instead of crystallization is the hard scale of calcite type, is easily washed out.
