Description
Technical field
The utility model belongs to that bazardous waste is innoxious and recycling field, and in particular to a kind of degradable livestock and poultry
The anaerobic composting device of antibiotic in excrement.
Background technology
Antibiotic be the microorganisms such as fungi, actinomyces or bacterium produced in its metabolic process have kill or suppress it
One class chemical substance of his microbial action.Ratify antibiotic first from 1950s FDA to use
Make after feed addictive, feeding antibiotic consumption is increased rapidly in the world.China is antibiotic life maximum in the world
Produce one of state and country of consumption, it is estimated that, the usage amount of the current annual antibiotic of China reaches 210,000 tons, ranks the first in the world, its
In there are about 46.1% be used for livestock and poultry breeding industry, equivalent to 4 times of U.S.'s poultry industry usage amount in 1999.
At present, the excrement that annual livestock and poultry give off is up to industrial solid solid waste mostly 2,500,000,000 tons more than twice.Zhang Shu
Clearly, the research such as Halling-Sorensen, Gulknwska shows that animal is used after antibiotic, only absorbs profit by animal on a small quantity
With thering is 25%~75% or even 70%~90% to be excreted through alimentary canal with feces of livestock and poultry, urine.A part is with breeding wastewater
Into sewage plant, and antibiotic is not high in the clearance of sewage treatment plant, causes a large amount of antibiotic to pass through leaching, rainwash
Etc. surface water and groundwater is entered, various murders by poisoning are caused to aquatile, causes river antibiotic pollution, threatens mankind's drinking water
Safety；Another part as organic fertilizer apply farmland, cause soil antibiotic pollute, destroy edaphon structure of community and
Function, and transmitted to crops uptake and accumulation, and by food chain, the normal activities of influence plant, animal and microorganism,
The health of the final threat mankind.A large amount of antibiotic, which enter in environment, can also induce pathogen drug resistance, cause drug resistance pathogenic bacteria
Generation and diffusion, thus caused environmental pollution and eco-toxicity have been increasingly becoming a society of people's common concern and asked
Topic.Therefore we will have a profound understanding of the harm of abuse of antibiotics, be necessary to take measures to remove before feces of livestock and poultry utilization
Antibiotic residue therein, to reach the double shield of economic benefit and safety and Health.
Include China in countries in the world, feces of livestock and poultry is used in farmland frequently as organic fertilizer, although feces of livestock and poultry can give agriculture
Crop provides various nutriments, improves soil quality, but their soil application improves the risk of water and soil pollution, they
Pathogen and unstable material may be contained, such as organic nitrogen, titanium pigment and various antibiotic residues are in feces of livestock and poultry.
The antibiotic that the research such as Rynk, Kuchta shows to work as in feces of livestock and poultry, which enters in soil or lake, metastable to have 5-9
Individual month.Antibiotic long-term existence brings huge potential risk in environment to the public and environmental health.
Composting process is common dung recovery, innoxious means, is at home and abroad widely studied and answers for a long time
With.Focused mostly in recent years in antibiotic research is removed to livestock excrement composting in sulfamido, and it is fresh to tetracycline antibiotics
Have been reported that, especially degraded of the anaerobic composting to tetracycline antibiotics in feces of livestock and poultry only has fragmentary research.
Anaerobic composting method is one of main processing ways of feces of livestock and poultry, can effectively pollution abatement by anaerobic digestion
Substance environment load, and reclaim available biomass energy.Therefore, during anaerobic composting, livestock excrement composting mistake is verified
The main-control factors and key parameter of journey tetracycline antibiotics conversion degraded, for the ecological wind of exploitation animal waste antibiotic
Cut control technology and technical basis is provided in danger.
