Description
Technical field
The invention belongs to technical field of waste gas treatment, and in particular to a kind of livestock and poultry farm give up in odor purification system and its
Application method.
Background technique
With society, economic development, the variation of essence is occurring for livestock and poultry cultivation mode, structure, mode.On the one hand it gets over
It goes down town and works come more rural laborers, farmers' income improves, and causes rural area livestock and poultry free-ranging fewer and fewer；On the other hand, with
The rise of feed price, pestilence frequently occur, the risk of peasant free-ranging livestock and poultry, added cost also lead to rural area free-ranging gradually
It reduces.In recent years, the progress of China's agricultural cience and farming techniques, especially animal products price continuous rise, cause social funds big
Amount turns to aquaculture investment, and livestock and poultry cultivation has been pushed quickly to specialized, scale transformation, to cause China's livestock breeding model
The transformation of essence occurs.Intensive culture has become the dominant direction of China's animal husbandry development.
Intensive culture is different from peasant's free-range mode, and caused environmental problem is also different.What free-range mode livestock and poultry generated
Excrement has returned to field directly as farmyard manure, and environmental problem is relatively fewer.Intensive culture causes livestock waste largely to be concentrated
It generates, there are many environmental problems to be difficult to handle.In the fast development process of intensive livestock and poultry industry, cultivation is seriously ignored
The comprehensive treatment of pollution, Treatment process research and development relatively lag behind, and numerous farms is caused to become a very important pollution sources.Poultry
In fowl breeding process a degree of pollution can be caused to atmospheric environment, water environment, ecological environment.State Environmental Protection Administration's tissue
23, whole nation provinces, autonomous regions and municipalities carry out scale animal and poultry cultivation industry Survey of contamination status of sea products the results show that scale livestock and poultry are supported
Grow industry pollution and three big outstanding problems are presented: first is that excrement discharge amount is big, about 2,900,000,000 tons of year discharge, be industrial solid castoff
2.4 times, the excrement amount that only large-scale cultivation generates is equivalent to the 30% of industrial solid castoff.Second is that Livestock pollution object spread area
Wide and harm is big, and the COD discharge amount of feces of livestock and poultry is up to more than 100,000,000 tons, considerably beyond the sum of the discharge amount of industry and sanitary sewage.
Third is that more serious ecological pressure is presented.Realize aquaculture sustainable development, it is necessary to improve the ecological environment, harmless treatment and
Resource utilization animal waste realizes the coordination of breeding production and environmental protection.
Foul smell caused by the mainly farm that centralization-breeding factory pollutes environment and surrounding air.Research
Show that pig manure can produce 230 kinds of odorants, most of ingredient of stench is irritant to humans and animals and toxicity.It is therein
Pernicious gas mainly has the ingredients such as ammonia, hydrogen sulfide, phenol, indoles, scatol, methane and thio-alcohol.The production of such numerous foul smell
Raw, mainly carbohydrate and itrogenous organic substance decompose under the environmental condition of anaerobism releases band tart flavour, smell of putrid egg, fish raw meat
The special penetrating odors such as taste, rotten Chinese cabbage taste.If odor concentration is low, the production performance and growth of livestock and poultry can be reduced；If dense
Degree is high, and humans and animals suck for a long time, and odorant can change neuroendocrine function, reduces metabolism and immune function,
The health of people is influenced, and declines Production of Livestock and Poultry power, morbidity and the death rate increase.The a large amount of dust of farm's discharge carries quantity
The microorganism of huge number can propagate 30km or more with the wind, can cause aftosa, bird flu, Escherichia coli, anthrax and pig,
The propagation of the epidemic diseases such as horse, ox, sheep lung epidemic disease, endangers the health of humans and animals.Dust pollution increases Inhalable Particles of Atmosphere, dislikes
The sanitary condition of Hua Liao farm ambient atmosphere and environment improves the eye of humans and animals and respiratory disease disease incidence.According to survey
Fixed, 1 is produced per year 100,000 pig farms, can discharge 147kgNH to atmosphere per hour3、13.4kgH2S, 23.9kg dust and 13.8 hundred million
A thallus, the pollution radius of these substances is up to 4.5~5.0km.
Currently, harm of the pernicious gas to livestock and poultry cultivation itself is reduced in order to improve air quality in livestock and poultry cultivation room,
The mode generallyd use is to reinforce breeding house ventilation, and drawback is: (1) source of pollutants in air is waste in giving up,
Air is to rise to be discharged from top again from ground waste in giving up during ventilation, and it is empty into house to increase pollutant in waste
The release of gas, it is little to subaerial livestock and poultry zone of action air quality improvement；(2) draft type as is not to gas
Body carries out in the atmosphere that purification is directly discharged to except room；(3) in pig farm dirt gas pollutant induction pig disease and
Pathogen propagation therein is the root of pig farm pestilence outburst, brings huge impact to cultivation industry；(4) farm discharges
Ammonia be big gas ammonia one of main source, it is to make that the ammonia in atmosphere, which is the main presoma of secondary particulate particulate matter again,
At one of the arch-criminal of haze, from the point of view of improving atmospheric environment, it is also desirable to control the emission intensity of livestock and poultry farm.
