Description
Technical field
The present invention relates to a kind of water filter, particularly relate to a kind of Household integral water filter.
Background technology
Water molecules be by hydrogen and oxygen two kinds elementary composition.Be the liquid of colorless and odorless at normal temperatures, be called as the source of human life.In physical environment, water resources major storage in river, lake, sea and ground inferior.
In China, drinking water pollution is very serious, what meet drinking water standard only accounts for about 30% of total Water, its polluted-water is primarily of industrial pollution, domestic pollution, agricultural pollution three bulk composition, the disease of the mankind 80% is owing to having drunk contaminated water, investigation result shows: China also has 5,000,000 people to cause disease and dead because drinking unhealthy water every year, and it is extremely urgent to solve water pollution.
Household drinking water is primarily of city planting ductwork central water supply, its water pollution is mainly because water supply network and municipal administration process in early stage imperfection cause, at present, in domestic water, harmful material mainly contains: heavy metal, COD, BOD, SS, nitrite, bacterium etc.Meanwhile, due to the northern area of China, because being subject to natural environment influence, the severe overweight of calcium-magnesium content in its water body, hardness in water body is caused to strengthen, also quite remarkable to the harm of human body.
At present, existing family expenses are directly drunk equipment and are mainly contained domestic filtered machine, water softening device, barreled drinking water machine.Water softening device is that its technique can only remove the hardness in water body by the softening water processed of resin; Barreled drinking water machine on drinking water machine, divides drink after the pure water encapsulation after having unified process, and its tap water must use in a short time; Domestic filtered machine is Household water purification equipment the most general on the market, its principle of work is that pending water makes it water purification through multi-stage filter core process, and conventional filter core is that one or more in PP cotton, medical stone, gac, ultrafiltration, reverse osmosis, coconut husk filter core are in series.
Because household water-purifying machine generally needs three to be in series to the filter core of Pyatyi, therefore general household water-purifying machine build is relatively bigger than normal, have different maintenances due to often kind of filter core simultaneously and change requirement, its pipeline connects also relative complex, and filter element replacing cost is also relatively bigger than normal.Again because household water-purifying machine belongs to novel small household appliances, basic user is still not very clear its structure, and therefore more renew cartridge operation is very inconvenient, makes a lot of water-purifying machine cannot reach water purification requirement.
Summary of the invention
In order to overcome the deficiency that prior art exists, the invention provides a kind of is main body filter material with hollow fiber nanofiltration membrane, and the integration that PP is cotton, cocoanut active charcoal is auxiliary filter material is detachable, the convenient Household integral water filter installed.

Household integral water filter as described in Example 1, upper Fiber Diameter is 50mm, and length is 100mm.Described hollow fiber nanofiltration membrane material is polyimide, and its pore size filter is 2nm, and the cotton filter element filtering aperture of described PP is 5 μm, and its inside channels skeleton aperture is 20 orders.
The present invention is used for the results are shown in Table shown in 1 before and after water treatment:
Table 1
| Somewhere, south (before process) | Somewhere, south (after process) | Somewhere, the north (before process) | Somewhere, the north (after process) | |
| Turbidity (NTU) | 1 | 0.1 | 1 | 0.1 |
| Iron ion content (mg/L) | 0.05 | Do not detect | 0.1 | Do not detect |
| Monovalent salt (mg/L) | 170 | 75 | 650 | 370 |
| Divalent salts (mg/L) | 35 | 5 | 270 | 40 |
| Total hardness is (with CaCO 3Meter) (mg/L) | 16 | 3 | 150 | 25 |
| PH | 7.3 | 7.1 | 7.8 | 7.3 |
| Total number of bacterial colony | ≤100 | Do not detect | ≤100 | Do not detect |
As can be seen from Table 1, the present invention can well realize water body purification, and the multi-stage filter core of replaceable household water-purifying machine makes household water-purifying machine use more convenientization, simplifies.
Embodiment 3
Considered the impact of different structure, its result is as shown in table 2:
Table 2
| 1 | 2 | 3 | |
| Upper filter length (mm) | 150 | 150 | 150 |
| Upper Fiber Diameter (mm) | 90 | 120 | 120 |
| The cotton size (inch) of PP | 5 | 5 | 5 |
| The cotton aperture (um) of PP | 5 | 5 | 5 |
| Nanofiltration membrane area (mm2) | 0.6 | 0.8 | 0.8 |
| Nanofiltration membrane aperture (nm) | 2 | 2 | 3 |
| Water flux (gallons per day) | 80 | 100 | 120 |
| Monovalent salt rejection (%) | 58 | 58 | 50 |
| Divalent salts rejection (%) | 89 | 89 | 81 |
As can be seen from Table 2, under equal length, increase the water flux that nanofiltration membrane area can increase filter core within the specific limits, and do not change its performance; Meanwhile, under equal length and nanofiltration membrane area, select the nanofiltration membrane in different nanofiltration aperture can change the rejection of effluent flux and monovalent salt and divalent salts.According to practical situation, suitable product can be manufactured aborning.
What finally illustrate is, above embodiment is only in order to illustrate technical scheme of the present invention and unrestricted, although with reference to preferred embodiment to invention has been detailed description, those of ordinary skill in the art is to be understood that, can modify to technical scheme of the present invention or equivalent replacement, and not departing from aim and the scope of technical solution of the present invention, it all should be encompassed in the middle of right of the present invention.
