Description
Technical field
The invention belongs to biological treatment field, and in particular to a kind of scrap generated based on rubbish with fireworks firecracker firing
Microbial treatment method.
Background technique
Set off fireworks during the Spring Festival firecracker, paste new Year scroll custom it is long-standing in China, although in more and more big cities
City has carried out firework control measure during the Spring Festival, but vast rural area and small city volume during the Spring Festival is seted off to show and more be drilled more instead
It is strong；Which results in a large amount of fireworks firecracker firing scrap is produced during the Spring Festival；By taking Jinan City as an example, whole city's phase in Spring Festival last year
Between raw more than 800 ton of fireworks firecracker firing scrap of common property, odd-numbered day highest generates nearly 100 tons of fireworks firecracker firing scrap amount, though at present
Without specific statistics, but it is ensured that the total amount of fireworks firecracker firing scrap is generated during the national Spring Festival at ten thousand tons or more.
In addition to the paper scrap of flood tide in these scrap, also contain more valuable copper, aluminium, magnesium elements and rare earth element
With a small amount of heavy metal element etc., these scrap often use centralized burning or direct landfill disposal, cause secondary pollution；More than
Both rubbish are all that waste product manufacturer holds it scorn to recycle since cost recovery is higher, recovery utilization rate is low.
