Description
Technical field:
The present invention relates to a kind of air cleaning formaldehyde high-efficiencies using complex biological enzyme in Techniques for Indoor Air Purification field
Enzyme and preparation method thereof.
Background technique:
With population migration, the promotion of people's living environment, people pay more attention to indoor air quality.And indoor (culvert
Covering the places such as general family, office, art space) volatile organic matters such as formaldehyde, the dimethylbenzene of releases such as finishing, furniture are serious
Beyond national standard, harm to the human body be can not be ignored.Activated carbon adsorption, strong oxidizer (chlorine dioxide are mostly used currently on the market
CN104941408A, ozone) oxidation, biological enzyme, dioxide photocatalyst titanium except the technologies such as formaldehyde, but active carbon is organic to volatility
The removal rate of object is not high and needs to regularly replace active carbon, and dioxide photocatalyst titanium need to be under specific wavelength ultraviolet light and formaldehyde is anti-
It answers, it is seen that the degradation rate of PARA FORMALDEHYDE PRILLS(91,95) is lower under light, and biological enzyme generally can remove in short term formaldehyde, but can not persistently remove formaldehyde, and
For the chlorine dioxide and ozone itself that oxidizing process uses to human body with regard to harmful, the organic by-products of generation are even more that toxicity is very big.Separately
It is outer to be easy to produce high-concentrated ozone using the physical techniques such as anion, low temperature plasma, secondary hazards are caused to human body.
Summary of the invention:
In order to solve prior art problem, it is an object of the invention to overcome the shortcomings of the prior art, one kind is provided
Composite efficient enzyme, can efficiently and sustaining degradation room air in formaldehyde.To achieve the goals above, the present invention is using as follows
Technical solution:
A kind of air cleaning formaldehyde high-efficiency enzyme, it is characterised in that: the formaldehyde high-efficiency enzyme is by formaldehyde dehydrogenase, complexing agent
With storage enzyme body composition, storage enzyme body is Organometallic framework material, and complexing agent is multiamino compound, and formaldehyde high-efficiency enzyme is slowly long-acting
Release formaldehyde dehydrogenase, continue reacted with the formaldehyde of low concentration；Be further described to above-mentioned technical proposal: described is more
Amino-compound is one kind of EDETATE SODIUM or glycine；Above-mentioned technical proposal is further described: the formaldehyde high-efficiency
Enzyme prescription quality percentage are as follows:
Formaldehyde dehydrogenase 5~30%
Multiamino compound 0.1~1.5%
Organometallic framework material 0.01~0.5%
Deionized water 10~93%
The sum of each component mass percent is 100%.
Above-mentioned technical proposal is further described:
Formaldehyde high-efficiency enzyme step of preparation process is as follows:
1) it according to indoor formaldehyde concentration height, selects vigor in the formaldehyde dehydrogenase 5~30% of 300~3000U/mg, adds
Enter deionized water 10~93%, revolving speed r is 100~3000r/min, 36 DEG C of constant temperature, at the uniform velocity 2~4h of stirring is kept, to allow formaldehyde
Dehydrogenase is evenly dispersed in deionized water；
2) 0.01~0.5% Organometallic framework material is added, revolving speed is 100~3000r/min, keeps constant temperature 36
DEG C, at the uniform velocity 4~10h of stirring facilitates Organometallic framework material and preferably absorbs formaldehyde dehydrogenase；
3) for the multiamino compound of addition 0.1~1.5% as complexing agent, revolving speed is 100~3000r/min, keeps permanent
36 DEG C of temperature, at the uniform velocity 2~4h of stirring, formaldehyde dehydrogenase is locked in Organometallic framework material.
The present invention compared with prior art, has the advantages that following significant:
1. the present invention fully takes into account the rate of release of formaldehyde at high temperature and speeds, and uses high temperature fumigation on the market at present
Or hot wind stripping can not be complete by the Form aldehyde release in furniture, plate, formaldehyde dehydrogenase spray treatment once or several times
High temperature can only be discharged to aerial Degradation Formaldehyde to fall, can not persistently be had for low concentration formaldehyde remaining in later period plate
Effect degradation.Therefore the present invention is using storage enzyme agent long term storage formaldehyde dehydrogenase and the formaldehyde continuous action to slow release.
2. the present invention fully takes into account bring secondary pollution problem during handling formaldehyde, so not using sulfurous
The oxidants such as sour hydrogen sodium, urea, chlorine dioxide, ozone and ammonium agent.
