Greatly improve the aesthetic feeling of product.But the release that can volatilize in paint production, dilution, spraying process and during subsequent cure has
Machine exhaust emission.The comparison of ingredients of Organic Waste Gas Pollution object is complicated, mainly has low-molecular-weight organic compound and macromolecule organic
Compound, the water solubility and degradability of height organic compound differ greatly, especially as surface spraying, plastic processing, chemical industry,
The organic exhaust gas of the generations such as rubber, pharmacy, chemical fertilizer, printing, weaving, the solvent and diluent of surface spraying have benzene, toluene, diformazan
Benzene etc. is insoluble in the stronger water of polarity, and benzene,toluene,xylene is non-polar high polymer organic compound substance, also there is readily soluble water
The low poles low-molecular-weight organic compound such as methanol, ethyl alcohol, acetone, aliphatic ketone, formaldehyde, acetaldehyde.
At present to VOCs treatment there are no preferable method, more commonly used method is to utilize microbial technology
To reach clean-up effect.The method using microorganism using the organic component in exhaust gas as the energy of its vital movement or other support
Point, through metabolic degradation, it is converted into simple inorganic matter CO2, water etc. and cell component.Foreign countries have started since the eighties
Industrial waste gas is handled with biotechnology, technology cleaning is easy to operate, can be carried out reacting at normal temperatures and pressures, especially
Its low concentration, high flow capacity waste gas purification on have received good effect, biological waste gas purification is the new technology of " green ".Mesh
In preceding biological treatment, because being influenced by factors such as microbial bacteria, bio-film colonization, air quantity, humidity, temperature, residence time, pressure,
The problems such as denaturation, the microbial activity reduction of filtrate and biofilm easily occurs, the short-circuit flow for causing air film to contact, to make organic
The purification efficiency of exhaust emission reduces.In addition, the water solubility and biological degradability to organic pollutant require also higher, biology
The starting of reactor, microbial acclimation, treatment process duration and the specific surface area of filler are few, porosity is few, ventilation resistance
Power is the main problem of current filler greatly.The less effective of filler causes that bacterial activity reduces, equipment volume is huge, the residence time
Too long, easy blocking, influences mass transfer effect, keeps filler service life short, and then directly affect the operating cost of whole system.For
This, many manufacturers and knowledgeable people exclusively carry out exploitation and development, but there has been no comparatively ideal products to emerge so far.
