Abstract
The utility model relates to a water purification system, in particular to a nano-filtration water purification system adopting the separation and treatment technology of nano-filtration film. The nano-filtration water purification system of the utility model is ordinally connected by a water-feeding processing system, a pre-positive pretreatment filter device, a pressurizing processing device, a main filter device, a pressurizing water storage device and a water-yielding processing system. The pre-positive pretreatment filter device comprises the connection of PPF filter and precise filter in turn; the main filter device is a nano-filtration processing system adopting CTA acetyl cellulose nano-filtration film, comprising the outer case and the nano-filtration film arranged in the outer case; an activated carbon filtering and adsorbing device is arranged between the main filter device and the pressurizing water storage device. The utility model can improve the water quality for human by yielding water reaching the national nano-filtration water purification quality standard, decrease the earlier stage processing step with only one filtration system to meet the requirement of water yielding, and reduce the equipment investment cost.
Description
Technical field
The utility model relates to a kind of water cleaning systems, particularly adopts the nanofiltration water cleaning systems of nanofiltration membrane separation treatment technology.
Background technology
Traditional potable water logos will be by flocculation, precipitation, sand filtration and chlorination make a return journey suspended substance and bacterium in dewatering, and very low to the effect that removes of various resolvable chemical materials.Many regional water resources hardness exceed standard on the earth, also have the increasing environmental pollution of water resources, contain objectionable impuritiess such as aminate, Humus, heavy metal ion in many water sources.Add the raising of various countries' drinking water standard, " the drinking water deep processing " that can remove various organism and harmful chemical is subject to people's attention day by day.At present a lot of purified water treatment devices reaches softening and clean China with tap water through desalination and dephosphorization treatment by " drinking water deep processing " exactly, and then capable of direct drinking.A variety of water purifying processing systems are arranged, and it generally all comprises main filter process such as charcoal absorption, ozonize and membrane sepn.And main microfiltration membrane and the ultra-filtration membrane that adopts all can not remove various low material molecule materials in the existing membrane sepn, and effect is undesirable.Adopt chemical treatment method to tend to bring bad side effect.
The utility model content
The purpose of this utility model just is to provide a kind of people's of raising water water quality, and water outlet reaches national nanofiltration water purification water quality standard, reduces the processing links in early stage, only through one filtering system, just can reach the water inlet requirement with system, reduces the facility investment expense.
The purpose of this utility model is achieved through the following technical solutions: the utility model comprises the nanofiltration water cleaning systems, comprise successively the water inlet treatment system, preposition pretreatment filtering device, pressurization process device, main filtration unit, the water storage device that pressurizes that connect, go out water treatment system, described preposition pretreatment filtering device is made of the PPF strainer and the accurate filter that connect successively; Main filtration unit is for adopting the nanofiltration treatment system of CTA cellulose acetate nano filter-membrane, and it is made of shell and the nanofiltration membrane that sets in the enclosure; Between described main filtration unit and pressurization water storage device, also be provided with the activated carbon filtration adsorption unit.
It can be provided with connection one rearmounted bacteriostatic activated carbon filtration unit the utility model before going out water treatment system.
The utility model is to be major parts with the nanofiltration membrane, nanofiltration membrane is a charged membrane, can electrically adsorb,, can partly remove to electrically high F ion etc., and has a nano level aperture, macromole can not pass through, and the water molecules of free state partly passes through, and NaCl partly sees through, calcium ion, magnesium ion more small part can pass through.Nanofiltration membrane can soften and appropriate desalination tap water under low pressure (relatively reverse osmosis), but also can remove variously have, inorganic substance, (especially carcinogenic substance), microorganism and dissolved organic matter can be referred to as " a many-side people ", thereby are favored day by day.The effect of nanofiltration membrane in the tap water preparation.(1), can remove anhydrate in, colourity, peculiar smell, trichloromethane precursor (by product during chlorination is carcinogenic substance), agricultural chemicals, chemical fertilizer and total organic charcoal, (2), can remove the middle hardness composition that anhydrates, sulfide, vitriol, nitrate, fluorochemical, boride, objectionable impuritiess such as arsenide.(3), can remove the middle salt that anhydrates, bacterium, virus and thermal source.The utility model is owing to its beneficial effect after adopting above-mentioned technical pattern is: included the advantage of above water treatment machine, and avoided secondary pollution.Can set up a kind of water way of health.
Its beneficial effect was after the utility model adopted above-mentioned technical pattern: 1) remove organic pollutant, chlorine residue, impurity, germ and heavy metal in the water; 2) keep beneficial mineral matter and trace element in the water; 3) the heat energy consumption is fully used, and the heating expense can reduce more than 30%; 4) the washing composition consumption can reduce by 60%; 5) fabric life prolongs 30%.6) equipment (central air-conditioning, water-heater, washing machine etc.) of paddling is insured a like-new appearance indefinitely, and the life-span prolongs 50%.Use nanofiltration water purifying advantage to be in the life: 1, bathing uses water purification can make the more soft tooth of skin more healthy.2, reduce alopecia, dandruff, skin itching and infectation of bacteria.3, sanitary ware do not have incrusted deposit, no sand erosion.4, the diet water is more fresh and sweet, health.5, with the pure white soft health of water purification laundry.6, hinder silt, prevent that fouling from not having gas corrosion, water-heater is more durable and can prevent to stop up the danger of explosion
