The utility model embodiment, a kind of cleaning apparatus of tap water, be shaped on the body 1 of cavity body in comprising, this body 1 feed-water end is furnished with first filtering membrane 11, body 1 the water side be furnished with second filtering membrane 12, side clearance is equipped with one deck DDF filtering layer 2 at least in second filtering membrane 12, DDF filtering layer 2 opposite sides are equipped with one deck activated carbon layer 3 at least, activated carbon layer 3 opposite sides are equipped with one deck KDF filtering layer 4 at least, these KDF filtering layer 4 opposite sides are equipped with one deck molecular sieve 5 at least, be equipped with at least one strata iodine resin layer 6 between the molecular sieve 5 and first filtering membrane 11, and be set in sequence in described body 1 cavity body.

Present embodiment is achieved in that general argumentation: polyiodine resin layer 6 is one deck, and the interval location of this polyiodine resin layer 6 and first filtering membrane 11, molecular sieve 5 all is equipped with and flows to guide plate 7.Molecular sieve 5 is one deck, and the interval location of this molecular sieve 5 and KDF filtering layer 4 is equipped with and flows to guide plate 7.KDF filtering layer 4 is one deck, and the interval location of this KDF filtering layer 4 and activated carbon layer 3 is equipped with and flows to guide plate 7.Activated carbon layer 3 is divided into mutually side by side and is first activated carbon layer 31 and second activated carbon layer 32 of one deck, and first activated carbon layer 31 and second activated carbon layer 32 interval location be equipped with and flow to guide plate 7.The interval location of second activated carbon layer 32 and DDF filtering layer 2 is equipped with and flows to guide plate 7; DDF filtering layer 2 is one deck.Preparation has one deck nonwoven layer 7a at least in the middle of flowing to guide plate 7.Body 1 two ends seal respectively and are fitted with feed-water end body 13 and water side body 14; Described feed-water end body 13 inner chambers are equipped mutually with first filtering membrane 11; Body 14 inner chambers in water side are equipped mutually with second filtering membrane 12.

Feed-water end body 13, water side body 14 and body 1 screw thread mutually spin, and feed-water end body 13, water side body 14 have sealing-ring 15 with the pressing of contact surface mutually of body 1.Feed-water end body 13, water side body 14 are the cylinder of profile continuity mutually with body 1, and the tail end of water side body 14 is shaped on the faucet 14a that shrinks to the center.

A kind of polyiodine resin, it is a kind of contact high-efficiency broad spectrum aqueous disinfectant that grows up gradually in the sixties in this century, and it can kill Gram-positive bacillus and negative bacillus in the water effectively, and is also very effective to the deactivation of RNA, the DNA of virus, and the sterilizing rate height, speed is fast.Water after polyiodine resin sterilization, its look, smell, flavor etc. is all not too influenced, compares with other sterilizing agent, its formulation, preparation technology and sterilization method all have certain superiority, are a kind of good drinking water disinfection media.

Polyiodine resin is that a kind of novel disinfection material of treated synthetic is the sterilised medium of a class contact, penetrance after being reacted under certain condition by industrial chemicals and poly-iodine solution.For safety, used active carbon filtration before this, done two benefits like this, the one, the adsorptivity of carbon can be held back the bacterium corpse that part is die, and the 2nd, carbon itself is exactly good filter material, and it also can shield unnecessary iodine absorption to iodine.Sterilization mechanism: when the moment that bacterium protein directly contact with polyiodine resin in water, immediately by attack, the generation modification, solidify, bacterial enzyme change system destruction, and cause microbial death such as germ,

The working process of the utility model embodiment:

Intake in body 1 bottom; through the impurity in the filtered water of first filtering membrane 11; foreign material such as silt are again by flowing to guide plate 7, through polyiodine resin layer 6 kill bacteria; flow to molecular sieve 5 by flowing to guide plate 7; filter once more and remove heavy metal,, flow to KDF filtering layer 4 again by flowing to guide plate 7; by flowing to guide plate 3; flow to first activated carbon layer 31, remove the peculiar smell in the water, adsorb unnecessary iodine; play a protective role; for allowing the taste of water more sweet, the surplus iodine of more effective removal is provided with one filtration, second activated carbon layer 8 again; flow to DDF filtering layer 2 through flowing to guide plate 7 again, again through the 12 direct water outlets of second filtering membrane.Water has passed through the multiple tracks filtration, sterilization, and absorption, removing heavy metals makes the real health sweetness of water.

Polyiodine resin is compared maximum characteristics and is with other sterilant:

1, have sterilization speed and good sterilization effect fast, thoroughly kill bacteria, virus, sterilizing rate is more than 99.99%, filtration time 2 to 4 seconds.

2, safe in utilization, health, health: the micro-mineralizer-iodine element that sterilant discharged that uses in tap water is in the national Specification scope, to the human body beneficial.

3, filter surplus iodine in the water of back and can kill bacterium in the secondary pollution that the membrane filtration equipment produces, can remove the green alga in strainer and the tap water effectively.

4, have and meet the function that bacterium discharges: polyiodine resin has insoluble and stable in water, if in the water when aseptic, then medium keeps steady state, as then snap-out release sterilization of bacterium.

5, reasonable price: it is low to filter cost, and the filtration cost of ton water only is about 1.5 yuan.

6, the polyiodine resin filter plant is not easy obstruction, safeguards and changes conveniently.Be a kind of characteristics of multi-functional water purification filtrate molecular sieve:

1, it is strong that fluorine falls in tap water, arsenic removal has ion-exchange capacity, operation is simple, regeneration easily, do not harden, do not have characteristics such as the leachable of exceeding standard, working cost are low, be the most effective, most economical, safest at present novel fluorine, arsenic removal filter material of falling.

2, tap water deironing, demanganization have does not need aeration, need not cultivate active filter film, the operation pressure drop is little, good characteristic such as do not harden, and tens times the disposable removal of iron, manganese exceeds standard.

3, remove the sewage disposal and the water reuse of industries such as heavy metal is used for electroplating, pharmacy, electronics, iron and steel, food, electric power, weaving.

4, rich nutritive material (ammonia nitrogen, phosphide) is removed in the purification of swimming pool, fishpond, landscape water and rivers and canals, suppresses algae and microbial reproduction, need not change water, not need dosing, and the eternal cleaning of water body as before.

5, reverse osmosis, ultrafiltration, softening, mixed bed, the pre-treatment of EDI.

6, the purifying treatment of bath hot water, underground hot spring and water of condensation, the following exchange of 100 degree absorption ability does not subtract.

7, family, apartment, villa, school, hotel, dining room purification of water quality.

8, waterworks, sewage work, middle water reuse, reservoir are administered, homemade well purifies, the rubbish sepage purifies, sewage disposal is butchered in breed.

Most preferred embodiment of the present utility model is illustrated, and various variations or the remodeling made by those of ordinary skills can not break away from scope of the present utility model.
