Embodiment
The utility model is by the following examples can the utility model will be further described, but scope of the present utility model is not limited to following embodiment.
Embodiment 1: see Fig. 1-2.
The present embodiment water purification system by inlet triplet for water ball valve 1, secondary preprocessing filter element 2, film bodyguard 3, polishing resin filtrate 3-1, KDF filtrate 3-2, extruded activated carbon filter core 4, entering water electromagnetic valve 5, topping-up pump 6, reverse osmosis membrane group 7, back pressure regulator 107, reverse checkvalve 8, post active carbon 9, smart valve 10, smart water quality monitor 412, return of waste water device 47, second reverse checkvalve 48, pressure pot 11, high-voltage switch gear 12, parts such as clear water faucet 13 grade form.
Tap water accesses water purification system through inlet triplet for water ball valve 1 by water pipe, inlet triplet for water ball valve 1 is arranged in the front end water inlet pipe of secondary preprocessing filter element 2, the water outlet of secondary preprocessing filter element 2 is communicated with the water-in of film bodyguard 3, and the water outlet of film bodyguard 3 is communicated with the water-in of extruded activated carbon filter core 4;
The rising pipe of extruded activated carbon filter core 4 divides two-way, and the first via is directly connected with clear water faucet 13 as domestic water; Second tunnel is connected with the water-in of topping-up pump 6 by entering water electromagnetic valve 5.
The water outlet of topping-up pump 6 is connected with the water-in of reverse osmosis membrane group 7, and the water outlet of reverse osmosis membrane group 7 is divided into two-way,
Return of waste water pipeline is provided with between the condensed water outlet and topping-up pump 6 of reverse osmosis membrane group 7, condensed water outlet is communicated with smart valve 10 with smart water quality monitor 412 successively, pipeline between smart water quality monitor 412 with smart valve 10 is provided with water outlet to be communicated with the water-in of return of waste water device 47, pipeline between entering water electromagnetic valve 5 and topping-up pump 6 is provided with backflow water-in, and the water outlet of return of waste water device 47 is communicated with this backflow water-in by the second reverse checkvalve 48.
The pure water outlet of reverse osmosis membrane group 7 is communicated with post active carbon 9 with pressure pot 11 respectively; That is: the pure water outlet of reverse osmosis membrane group 7 is divided into the two-way of connection after being connected with back pressure regulator 107 by reverse checkvalve 8, high-voltage switch gear 12 of leading up to is communicated with pressure pot 11, another road is directly communicated with the import of post active carbon 9, the check valve direction of reverse checkvalve 8 is pure water Way out, and the import of post active carbon 9 is communicated with pressure pot 11 by high-voltage switch gear 12.
The outlet of post active carbon 9 is connected with clear water faucet 13.
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 (polishing resin and KDF mixing filtrate carry 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, water enters RO film, utilizes reverse osmosis membrane separation technology to purify.
7, because of the sofening treatment of the front water source of film through film bodyguard, most incrustation scale is removed, so the smart valve being integrated with waste water ratio can be arranged to 1:2 than by traditional 3:1 only by useless, thus improves the rate of recovery of water, reduces discharge of wastewater.
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.
12, by the way, useless only than being reduced to trace waste water discharge by 2:1.
