Description

Ferment for VOC gas decomposition and preparation method and application thereof
Technical Field
The invention relates to an enzyme for decomposing VOC (volatile organic compound) gas as well as a preparation method and application thereof.
Background
With the continuous development of the home decoration market, various problems in home decoration are followed. Especially indoor environmental pollution, has attracted more and more attention due to its harmfulness to human bodies. The VOC, the source of indoor environmental pollution, also gradually floats out of the water. VOCs are organic (carbon-based) gases, also known as hydrocarbons, emitted by many different products. Common sources of volatile organic compounds in the room are decorative building materials, carpets, printers, furniture, paint thinners, glues, cosmetics and certain sprays, and also plastic products.
The main components of VOC are hydrocarbons, halogenated hydrocarbons, oxygen hydrocarbons and nitrogen hydrocarbons, which comprise benzene series, organic chloride, Freon series, organic ketone, amine, alcohol, ether, ester, acid, petroleum hydrocarbon compounds and the like. VOC is the abbreviation of volatile organic compounds, and the chemical substances (except heavy metals) harmful to human bodies in the wall paint are VOC. These volatile organic compounds include formaldehyde, ammonia, ethylene glycol, esters, and the like. When the VOC in a room reaches a certain concentration, symptoms such as headache, nausea, vomiting, hypodynamia and the like can be caused, and even convulsion and coma can be caused in severe cases, so that the liver, the kidney, the brain and the nervous system are injured, and serious consequences such as hypomnesis and the like are caused.
The existing VOC treatment method mainly comprises an active adsorption method, an induced air high-altitude discharge method and a combustion treatment method. 1. An active adsorption method: in the organic waste gas treatment process, the adsorption is one of the methods with good treatment effect and wider application, and the adsorbents comprise active carbon, diatomite, zeolite and the like, wherein the active carbon adsorption is most applied. Through adsorption system, not only can make VOC concentration greatly reduced, realize that waste gas discharge to reach standard, through gaseous desorption, the collection can be used for production again after adsorbing moreover. However, the method has the disadvantages of long treatment time, high cost, incomplete treatment and residual VOC. 2. An induced air high-altitude discharge method: the method is one of the most convenient methods used by common enterprises in the post of paint filling, sanding and the like, and has the advantages of low cost, easy operation and obvious effect. However, the high-altitude discharge is only pollution transfer, the pollution problem is not really solved, and the power and the air inlet installation height of the induced draft fan directly influence the induced draft effect. 3. A combustion treatment method: VOC is organic volatile substance, is easy to burn, can be treated by normal temperature or catalytic oxidation combustion, and gas is introduced into a boiler or an incinerator for combustion through a draft pipeline, but the high-temperature organic gas is subject to safety demonstration.
