Description
Technical field
The invention belongs to Waste Disposal Technology fields, and in particular to a kind of animal waste Treatment and recovery benefit
Method.
Background technique
With the horizontal development increasingly improved with Export-Oriented Agriculture of people 's material life, livestock and poultry breeding industry development is swift and violent.
Currently, China has become maximum meat, egg producing country in the world, poultry, pork, egg yield rank first in the world.2010
End, China pig, ox, poultry breeding stock have reached 4.6 hundred million, 1.1 hundred million, 53.5 hundred million.China's livestock and poultry breeding industry is towards profession
Change, large-scale development, but formed sharp contrast is that China's animal waste management and disposal technology development are opposite
Lag.The environmental pollution as caused by livestock and poultry cultivation in the past 30 years is increasingly severe [1], 2010 the 1st time National Agricultural pollution
Source findings of the survey show, livestock and poultry breeding industry excrement year yield up to 2.43 hundred million t, urine year, yield was up to 1.63 hundred million t [2].The whole nation
COD, the ammonia nitrogen discharge amount of livestock and poultry breeding industry respectively reach 1184t and 650,000 t, account for the ratio point of national total emission volumn
Not Wei 45% and 25%, account for the 95% and 79% of agricultural sources.According to " the 12nd five-year-plan of national animal husbandry development ", arrive
2015, national livestock and poultry cultivation total amount reached 1,400,000,000 (pig equivalents), and large-scale cultivation total amount reaches 700,000,000 (pig equivalents).It presses
Prevent and treat horizontal measuring and calculating according to existing Pollution from livestock and poultry, COD, ammonia nitrogen annual emissions it is estimated respectively reach 12,600,000 t and
800000 t.Pollution from livestock and poultry has become the important sources of China's environmental pollution.Agricultural pollution is controlled by emphasis of livestock and poultry cultivation
, cut down agriculture pollutants total emission volumn be included in National Pollutant overall control the binding indicator.Livestock and poultry cultivation is gradually by a
Body dispersion raising is changed to collective's intensive manufacture, using the high density of modernization, the merchandized handling mode of big quantity, this
The change of one production method is greatly promoted the raising of productivity level, is made that very to alleviate meat egg supply and demand pressure
Big contribution.The waste water of centralization-breeding factory discharge, which does not add, to be effectively treated and direct emission, seriously polluted cultivation periphery
Surface water, underground water and air, the section of the nearly half of the big water system in the whole nation seven is seriously polluted, 86% city section overproof water quality,
Various regions pollution dispute is continuous.As government gradually payes attention to pollution problem caused by centralization-breeding factory, living standards of the people
It is continuously improved and the gradually reinforcement of environmental consciousness is prevented and eliminated to animal dung sewage progress harmless treatment, resource utilization
The pollution of centralization-breeding factory animal dung sewage promotes China's green food, organic foodstuff production and agricultural is made to keep sustainable
Good momentum of growth has become very urgent task.It, will be to ring if ignoring the processing and comprehensive utilization of animal waste
Serious pollution is caused in border, and influences the sustainable development of aquaculture, it can be seen that, the harmless treatment of animal waste
It is very urgent with resource utilization.
Summary of the invention
In order to make up for the deficiencies of the prior art, the present invention provides what a kind of animal waste Treatment and recovery utilized
The technical solution of method.
A kind of method that animal waste Treatment and recovery utilizes, it is characterised in that including following step
It is rapid:
1) excrement is collected, excrement is filtered first with filter screen, excrement solid-liquid is separated, obtains solid manure and waste water,
Solid manure removes excessive moisture by high temperature drying；
2) waste water of step 1) being passed through marsh-gas fermentation tank, waste water temperature is adjusted to 55~60 °C, PH is adjusted to 5-6,
Using high-temperature anaerobic fermentation, biogas is obtained, fermentation discharging is dehydrated into biogas residue and biogas slurry, a part of biogas slurry back-mixing to biogas fermentation
Concentrated liquid fertilizer is made using film method for concentration in tank, another part biogas slurry；
3) biogas residue of the solid manure of step 1) and step 2 is first mixed, is then fed into heap ferment furnace and carries out heap ferment,
It is passed through boiler using biogas a part in step 2 to burn, the remaining cigarette for generation of burning is passed through heap ferment furnace, makes compost heap body
Compost 7-15d at a temperature of 55-60 DEG C obtains humus discharging, the foul gas in composting process with stench biofilter into
Row processing；
4) to the surface of compost heap body next time, remaining humus discharges for 10 ~ 20% coverings that step 3) humus discharges
High temperature drying, is then made chemical fertilizer.
A kind of method that animal waste Treatment and recovery utilizes, it is characterised in that received in step 1)
The process for collecting excrement is to be cleaned by broom and dustpan to the excrement in farm, and the excrement of cleaning is stored in accordingly
