Description
Technical field
The present invention relates to softening regeneration pre-treatment waste-water-free reverse osmosis water purifier automatically.
Background technology
Reverse osmosis water purifier without waste water comprises a circulation line, and this circulation line comprises reverse-osmosis treated device, water pump, energy storage canister and necessary valves and fittings.During operation, water in circulation line all carried out pre-treatment through pretreater, material for water treatment in pretreater is generally PP cotton and gac, these material for water treatment can only be removed colloidal solid in water, small organic molecule, heterochromatic, foreign odor and peculiar smell, and the ion component in water is not had removal effect.So, reverse osmosis water purifier without waste water is after operation for some time, ionic concn in water can be more and more higher, calcium, the magnesium ion that wherein also may comprise the fouling major cause, when the calcium in water, magnesium ion concentration were enough high, when namely water hardness was enough high, calcium, magnesium ion fouling on reverse osmosis membrane (forming the solids such as calcium carbonate, magnesiumcarbonate) was exactly inevitable, so this reverse osmosis water purifier without waste water uses in the northern China hard water areas and is far from suitable.
Also there is the people to make spent ion exchange resin in the pretreater of common anti-penetration water purifier, former water is first exchanged by ion exchange resin, calcium in water, magnesium ion are replaced with sodium ion, because sodium ion is non flouling behaviour, treated water is very effective to preventing calcium ions and magnesium ions fouling on reverse osmosis membrane like this.Problem is that the exchange capacity of ion exchange resin is limited, and along with the operation of anti-penetration water purifier, ion exchange resin is will be very fast saturated and lost efficacy, and need to could recover the function of exchange of calcium ions and magnesium ions in exchanged water by regeneration to the ion exchange resin that lost efficacy.For small-sized water purifier, regenerator is used sodium-chlor usually, and just there is following problems in this: 1, manually the reclaim equiment operation is pretty troublesome, and the user is difficult to accept; 2, autoregeneration equipment is complicated, cost is higher, reliability is lower; 3, the regenerator consumption is larger, has both produced larger running cost, and the discharging of regeneration waste liquid is contaminate environment again.
Also someone adopts the water quality stabilizers such as Si-P crystal to prevent the calcium ions and magnesium ions fouling.Si-P crystal is comprised of pharmaceutical chemicalss such as poly-phosphate and a small amount of silicate, certain dosing dosage corresponding to water-quality constituents during use, and this method suppressing also to obtain good effect aspect incrustation scale, is applied in undrinkable water in some water quality usually.If but use in reverse osmosis water purifier without waste water, the ionic concn due to the water in circulation line changes, and pharmaceutical quantities is wayward; In addition, the water that contains the high density Si-P crystal can be restricted when again utilizing, and for example this water is as being used for washing dish, washing rice that the user is unwilling to accept.
