Indoor decoration pollution has stimulation eyes, pharynx nasalis to the main influence of adult, leads to headache, dizzy, nausea, memory Power decline etc., while asthma, pneumonia can be also induced, severe patient can lead to the disease in terms of nasopharyngeal carcinoma, lung cancer and blood, therefore There is an urgent need to find the rapid and effective method for removing indoor pollution at present.
(3) method for commonly using removal interior decoration finishing pollution gas
1, plant null method
Indoor polluted gas is absorbed using flowers such as bracketplant, aloe, sansevieria trifasciatas.Plant carries out photosynthesis absorption two daytime Carbonoxide discharges oxygen, but night absorbs oxygen, discharges carbon dioxide, unfavorable to human body, is especially easy to pollen, flowers The effect of allergy sufferers, plant removes removing and harmful gas, is very limited, at most can only be as the supplementary means of Indoor Environment Treatment.Work as room When interior air pollution is serious, the effect of plant purification is with regard to smaller.Improvement feature low, required time for removal polluted gas efficiency Long, performance is unstable.
2, activated carbon adsorption
Activated carbon is a kind of porous carbon containing matter, it has highly developed pore structure, thus provides larger Surface area, can be come into full contact with gas (impurity), to impart absorption property specific to activated carbon, make its be very easy to Achieve the purpose that absorb and collects impurity.If but processing will be unable to not in time after activated carbon is to indoor polluted gas adsorption saturation Normal use, if type discharge will cause secondary pollution indoors.Active carbon adsorption is the organic gas to evaporating naturally With suction-operated, the organic solvent of pollution sources profound level can not be adsorbed.
Patent application CN103537167A discloses a kind of " pernicious gas vacuum adsorption machine ", including passes sequentially through pipeline company Absorber, buffer and the vacuum pump group connect at.Filling filter and adsorbent inside the absorber, inside the buffer Fill adsorbent, the adsorbent be magnesium and silicon chemical chelate, it is compound by the added multiple additives of natural mineral matter and At being a kind of to realize the device that is adsorbed to the polluted gas to volatilize naturally in environment using high-efficiency adsorbent.But it is existing Defect is that adsorbent equally will appear adsorption saturation, to cause the secondary pollution of pernicious gas;" absorption described in application simultaneously Machine " is also to carry out Adsorption for the gas volatilized naturally in environment, still to the polluted gas of indoor pollution depth of origin level It so cannot achieve efficient removal.
3, finishing pollution scavenger
Current miscellaneous formaldehyde scavenger is to remove formaldehyde, but in fact, first using method physically or chemically Aldehyde scavenger can only temporary closure pollution sources, in a short time prevent formaldehyde volatilize, formaldehyde pollution can not be thoroughly removed at all, this After layer protective film failure, formaldehyde still can largely release pollution room air;Some formaldehyde scavengers claim with formaldehyde to occur Chemical reaction, but can only also be reacted with the formaldehyde evaporated naturally on pollution sources surface layer, it is dirty that profound formaldehyde can not be solved Dye, if while formaldehyde scavenger react incomplete with formaldehyde, it is also possible to generate other noxious materials and cause secondary pollution.
4, air purifier
Air purifier price is more expensive, and is just decreased obviously using effect after some months, does not have effect finally. And air purifier substantially carries out taste removal using activated carbon, goes mould, and air purifier can not solve enclosure space Formaldehyde pollution, such as in cabinet, drawer.Simultaneously because air purifier mainly to the indoor polluted gas that volatilizes naturally into Row purification can not carry out purified treatment to the gas of pollution sources profound level, thus equally can not fundamentally solve room air Pollution.
Patent CN2808151Y discloses a kind of air purifier of removal finishing pollution, by will be polluted in room air Gas be absorbed into air purifier and handled, to effectively remove the pollutants such as formaldehyde therein, ammonia, benzene homologues, To achieve the purpose that purify air, since air purifier is just for the organic matter that has evaporated of interior, thus still without Method fundamentally solves room air pollution.

Patent CN101831207B discloses a kind of improvement finishing pollution all-weather nano photocatalyst product, in patent The micropore of unglazed matchmaker's ingredient ceramic crystal there is extremely strong adsorption capacity, pollutant that can be in efficient absorption surrounding air, together Shi Liyong photocatalysts are in the pollutant for having optical time division removal to be adsorbed.Such photocatalyst product is in addition to above-described limitation Outside, simultaneously because this method is simply possible to use in the indoor organic compound evaporated, the deep layer of pollution sources can not be polluted It is purged, therefore can not fundamentally reduce room air pollution.
6, other methods
Anion fine-purification generates anion using high voltage, by condensation and suction-operated, is adhered to solid phase or liquid phase is dirty It contaminates on object particle, forms big particle and settle down.Anion in air can not only make with fresh air, moreover it is possible to have sterilization except different The effect of taste, but the ion pair human body generated has larger harm.In addition there are the biological enzyme using biocatalytic reaction, ventilation The combination etc. of ventilation and above-mentioned various methods, can not efficiently remove indoor polluted gas, some methods are also easy to band Carry out secondary pollution.
To sum up, the method for commonly using removal indoor decoration pollution gas is for metope, furniture, floor, ceramic tile after finishing It waits the pernicious gas that natures evaporate and carries out, be a kind of passive method for administering room air pollution, not from interior The source of pollution is set out, fundamentally reduce source pollutant, thus using the above method processing after polluted gas residual still compared with It is more;Further, since indoor fit-up harmful gas volatilizees naturally needs the long period, had using the corresponding device processing of the above method Evil gas also needs for a long time, to which the injury caused by human body is also lasting.
