The theoretical test data analysis of the utility model and embodiment 1 and prior art:
Test conditions:
The comparison of the ratio of desalinization 1, during same pure water amount;
2, velocity ratio during same pure water amount comparatively;
3, under equal conditions: room temperature 25 degree, frequency 2 times/h is rinsed;
Filtering system A: traditional water-purifying machine is only useless compares 1:3;
Filtering system B: the utility model water-purifying machine is only useless compares 1:3;
Filtering system C: the utility model water-purifying machine is only useless compares 1:1.
One, as Fig. 3, traditional ratio of desalinization mutation analysis:
Because of the life-span of water amount reaction RO film, water amount is many, ratio of desalinization and flow indicator good, filtering system performance is strong, and RO film ratio of desalinization reach 90% be only qualified, the changes in contrast figure of ratio of desalinization; The comparison of ratio of desalinization during same pure water amount, when pure water amount is at 6000 liters, A ratio of desalinization is 91.3%, B ratio of desalinization be 97%, C ratio of desalinization is 92.5%
This shows that the utility model water-purifying machine adopts clean expense than time for 1:3, the work-ing life of RO film during ultra-traditional water-purifying machine employing far away 1:3 in its work-ing life, and the employing of the utility model water-purifying machine takes than time for 1:1 only, when its work-ing life and traditional water-purifying machine adopt 1:3, the life-span of RO film is substantially identical.
Two, as Fig. 4, the changes in contrast analysis of pure water flow velocity:
As Fig. 4 can obtain, the changes in contrast of pure water flow velocity; Comparatively, when pure water amount is at 6000 liters, A flow velocity is 87.3ml/min B flow velocity be 130ml/min C flow velocity is 99ml/min to velocity ratio during same pure water amount;
The utility model water-purifying machine adopts and only takes than time for 1:3, and its flow velocity is far longer than flow velocity during traditional water-purifying machine employing 1:3.And the employing of the utility model water-purifying machine takes than time for 1:1 only, its flow velocity is also greater than flow velocity during traditional water-purifying machine employing 1:3.
Its water total amount and wastewater flow rate be far smaller than traditional water-purifying machine adopt 1:3 time water total amount and wastewater flow rate.And the utility model water-purifying machine adopts and only take than time for 1:1, the water total amount when total water consumption manufacturing pure water is also far smaller than traditional water-purifying machine employing 1:3.
Therefore, the utility model purging method is adopted when guarantee film work-ing life, water-purifying machine can be realized and only take than being 1:1.
For optimizing raising developing result further, then RO film pure water backwash process after the positive flushing process of RO film pure water completes, positive and negative two steps hocket for once.
Embodiment 2: be also provided with Waste Water Treatment, comprises return of waste water device the 47, three reverse checkvalve 48, and parts such as smart water quality monitor 412 grade form.
The condensed water outlet of reverse osmosis membrane group 6 is by smart water quality monitor 412 He, first smart valve 8 is discharged, pipeline between smart water quality monitor 412 with the first smart valve 8 is provided with water outlet be communicated with the water-in of return of waste water device 47, pipeline between entering water electromagnetic valve 4 and topping-up pump 5 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 3rd reverse checkvalve 48.
Through the waste water of reverse osmosis membrane group 6, under the effect of topping-up pump 5, again pass through return of waste water device 47 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 6 at a high speed, again filter purification.Because the glassware for drinking water entering reverse osmosis membrane group 6 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.
After reverse osmosis membrane group 6, wastewater outlet side is provided with smart water quality monitor 412, can respond to the concentration of waste water salt, feed back to the first smart valve 8.When concentration value reaches certain set(ting)value, the first smart valve 8 opens water route, carries out instantaneous discharge, thus reaches flushing reverse osmosis membrane group 6 surface, reduces the effect of salt concn.
By the way, useless only than being reduced to trace waste water discharge by traditional 3:1.
Major technique ensures:
1, return of waste water device 47 is filled with desalination soft water filtrate.
2, filtrate adopts food grade polishing resin to mix with KDF, and polishing resin loadings is at 200-250 gram, KDF loadings 80-100 gram.
3. polishing resinous electricity conductance is dry after below 10us/cm pure water soaks 2 hours, then KDF55 is dried after 2 hours through 10%Nacl solution soaking, is respectively charged in filter-core shell.(centre adds the porose dividing plate of PP, distinguishes polishing resin and KDF)
4, 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.
5, polishing resin is without the need to regeneration.
6, 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.
