The utility model comprises a water inlet treatment system, a pre-pretreatment filtering device, a main filtering system, a pressurized water storage device and a water outlet treatment system which are connected in sequence, wherein the pre-pretreatment filtering device consists of a three-level PPF filter, a post-positioned antibacterial active carbon filtering device can be arranged and connected in front of the water outlet treatment system, the main filtering system comprises an ultrafiltration treatment device, a high-pressure pump and a nanofiltration treatment device which are connected in sequence, and the ultrafiltration treatment device consists of a shell and an ultrafiltration membrane arranged in the shell; the nanofiltration treatment device comprises a shell and a nanofiltration membrane arranged in the shell. The utility model discloses can be applicable to any practical water source to go out the water and reach the national water standard of receiving and straining, can improve present water situation, improve people's living condition.
Description
Technical field
The utility model relates to a kind of water cleaning systems, particularly adopts two height that separate of ultrafiltration membrane treatment technology and nanofiltration membrane treatment technology to purify the nanofiltration water cleaning systems.
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.Our company has developed a kind of nanofiltration water cleaning systems (ZL200420015664.7) to improve people's quality of water for this reason, makes water outlet reach national nanofiltration water water supply standard, thereby improves people's quality of life.Yet its characteristic owing to nanofiltration membrane of nanofiltration water cleaning systems makes it make it can only be installed in supporting use under pipeline water source of handling through chlorination, for then also inapplicable, because can reduce greatly the work-ing life of nanofiltration membrane such as the faces of land such as lake water, well water, underground water source.
The utility model content
The purpose of this utility model just be to provide a kind of can be applicable to any drinking water source, and effluent quality reaches national nanofiltration water water supply standard, can improve the present aqueous condition of using, living condition two that improve people separate the high nanofiltration water cleaning systems that purify.
The purpose of this utility model is achieved through the following technical solutions: the utility model comprises the water inlet treatment system that connects successively, preposition pretreatment filtering device, main filtering system, the pressurization water storage device, go out water treatment system, described preposition pretreatment filtering device is by being made of to three grades of smart PPF strainers thick of connecting successively, before going out water treatment system, can be provided with and connect a rearmounted bacteriostatic activated carbon filtration unit, main filtering system comprises the uf processing device that connects successively, high-pressure pump and nanofiltration treatment unit, the uf processing device is made of shell and the ultra-filtration membrane that sets in the enclosure; The nanofiltration treatment unit is made of shell and the nanofiltration membrane that sets in the enclosure.
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 the level of confidentiality of a receiving 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 has been included above every advantage, and has avoided secondary pollution.Can set up a kind of water way of health.
The utility model is owing to its beneficial effect after adopting above-mentioned technical pattern is: not only have the advantage of original nanofiltration water cleaning systems, the most important thing is that the utility model is applicable to various drinking water sources, city planting ductwork water, well water, river, lake water or the like.The structural advantages of this product has improved the popularity and the scope of application of product greatly, is convenient to promote.
