Description
Technical field
The utility model belongs to water-treatment technology field, relates to a kind of water treatment technology, especially relates to a kind of household water purification system.
Background technology
Household purified water treatment device common at present, primarily of preprocessing part, osmosis filtration part and storage three part of the purifying waste water composition of water.Common reverse-osmosis membrane element has very harsh requirement to water inlet free chlorine contents, requires contents of residual chlorine < 0.1mg/L, otherwise will destroy reverse osmosis membrane chip architecture, cause irreversible membrane element capability to decline.
Therefore; the water pretreatment part of existing household water-purifying machine generally need comprise three-stage filtration: first; suspended substance in the cotton filter element filtering tap water of polypropylene and large particulate matter; enter granulated active carbon filter core again and remove chlorine residue in tap water, trichloromethane and peculiar smell colourity, also will enter the various peculiar smell of sintering activity charcoal filter core again in planar water and impurity afterwards.After such three grades of pre-treatment, water just can enter reverse osmosis membrane filter element, is filtered out the materials such as the inorganic salt in water, heavy metal ion, organism, colloid, bacterium and virus by reverse osmosis membrane filter element.
Although through pre-treatment and the two-part filtration treatment of reverse osmosis, tap water can reach the standard of tap water, but after device long-time running, preprocessing part is used for organic gac in planar water, wherein by a large amount of microorganism of accumulation and organism, virtually becomes the hotbed that microorganism grows further, cause the secondary pollution at water source on the contrary, add the contaminated possibility of reverse osmosis membrane filter element, cause its degradation, finally make product water deteriorating water quality.
Use anti-oxide composite reverse osmosis membrane filter core to replace common reverse osmosis filter core, two-stage activated carbon filtration can be saved at the pretreatment stage at water source.Because anti-oxide composite reverse osmosis membrane has chlorine-resistant ability 26000ppm/hrs, namely under the condition of 0.5mg/L, Absorbable organic halogens runs 6 years, utilize anti-oxide composite reverse osmosis membrane there is extremely strong chlorine-resistant ability, tap water is when by reverse osmosis membrane, hypochlorous acid wherein can't damage diaphragm structure, on the contrary because hypochlorous acid molecule is little, neutral, can partly by fine and close diaphragm structure, can all carry out disinfection to Yuan Shui side and product water side simultaneously, play control, the effect of destroying microorganisms, decrease the irreversible membrane fouling of reverse osmosis membrane and harsh matting requirement, extend the work-ing life of anti-oxide composite reverse osmosis membrane further.
