Description
Technical field
It is used to reduce consumer waste incineration Wei gas Zhong bis- Evil the present invention relates to environment-friendly materials technical field, more particularly to one kind
The mix bacterium agent of English content.
Background technology
Over nearly 10 years, as Development of China's Urbanization is accelerated, China's Municipal Domestic Garbage Output is increased considerably.According to China
The data that urban environmental hygiene association provides, house refuse year yield is 440kg, National urban rubbish year per capita for current China
Yield is increased up to 1.5 hundred million t, and every year with 8~10% speed, and whole nation garbage amount over the years there are about 2/3 more than 6,000,000,000 t
City be absorbed in the predicament of garbage-surrounded city.At present, house refuse mainly has sanitary landfills, During High-Temperature Composting and burns three kinds of processing sides
Formula, although wherein central incineration one-time investment is higher, incineration tail gas secondary pollution complex treatment process, technical requirements
Height, but a kind of effective technology of minimizing of still can yet be regarded as, innoxious, stabilisation and recycling.And managed in this place
Journey produces the title bioxin for being also easy to produce " poison in century ", has investigation to claim, bioxin is produced in waste incineration and accounts for air
The 90% of Zhong content of dioxin, and be difficult in flue gas to decompose.
Bioxin is a kind of chloride strong toxic organic material, be there's almost no in nature, only by changing
Learning synthesis could produce.Quilt in 2001《Convention of Stockholm on persistence organic pollutant》It is appointed as 12 kinds of persistence
One kind in organic pollution.Bioxin is through everybody most laggard body of food chain richness product, because its is fat-soluble, be difficult removing property, from
And long-term hazards are produced to health, countries in the world government and the highest attention of the public have been caused at present.
Dioxin chemical toxicity is big, property stable, and difficult degradation causes significant damage to environmental and human health impacts.
And microbial degradation bioxin is used, cost is low, and environmental pollution is small, can make resource regeneration, has a good application prospect.
The content of the invention
The technical problem existed based on background technology, the present invention proposes a kind of for reducing in consumer waste incineration tail gas
The mix bacterium agent of content of dioxin, produced by being handled using mix bacterium agent obtained by the present invention during consumer waste incineration tail gas

Protection.
It is proposed by the present invention a kind of for reducing the mix bacterium agent of consumer waste incineration Wei gas Zhong content of dioxin, by mixing
Strain scale-up medium and water are 1 by volume：50-100 is mixed to get.
Preferably, mixed bacteria is intended without branch acid by streptomyces cinereogriseus, geotrichum candidum, trichodermaharzianum, halobacterium halobium and sulphur
Bacterium constitutes.
Preferably, mixed bacteria scale-up medium is by streptomyces cinereogriseus scale-up medium, geotrichum candidum scale-up medium, healthy and free from worry
Trichoderma scale-up medium, halobacterium halobium scale-up medium, sulphur amycolatosis scale-up medium are 1 by volume：0.5-
1：0.5-1：0.5-1：0.5-1 is mixed to get.
Preferably, viable count is all higher than 2 × 10 in above-mentioned scale-up medium7Individual/mL.
Preferably, the preserving number of streptomyces cinereogriseus (Streptomyces cinereogriseus) is CGMCC 4.342.
Preferably, the preserving number of geotrichum candidum (Geotrichum candidum) is CGMCC 2.1135.
Preferably, the preserving number of trichodermaharzianum (Trichoderma koningii) is CGMCC 3.2064.
Preferably, the preserving number of halobacterium halobium (Halobacterium halobium) is CGMCC 1.1952.
Preferably, the CGMCC 1.1144 of sulphur amycolatosis (Amycolatopsis sulphurea).
The present invention compared with prior art, during handling consumer waste incineration tail gas using mix bacterium agent obtained by the present invention
Produced flying dust, makes the degradation rate of bioxin in flying dust reach 93-97%, greatly reduces the discharge of bioxin, realizes
The protection of environment.
