With the continuous improvement of people's living standards, China's livestock and poultry breeding industry is grown rapidly.Livestock and poultry breeding industry has become me
One of pillar industry of state's agricultural development, wherein pig, the sheep number of animals raised rank first in the world, large scale of pig farm reached 40% with
On.But the fast development of large-scale cultivation industry, breeding waste (solid, liquid) is caused to increase significantly, problem of environmental pollution
Also it becomes increasingly conspicuous.
Regulations modellings in China are looked into fowl feces of farm and are generally handled using celebrating oxygen hair alcohol technique at present.Anaerobic fermentation technology
It is widely used in terms of the bioenergy exploitation biogas of sound feces of farm, is realizing feces of farm recycling
Meanwhile effectively reduce the primary pollution of feces of farm.However, while waste progress anaerobic fermentation utilization is handled,
Also a large amount of, concentrate, secondary pollutant-biogas residue and biogas slurry are produced.
Along slag by aerobic hair ester, organic fertilizer is made and returns soil, is utilized；But meagre profit is in for China
For the cultivation industry of operation, the existing required investment of biogas residue treatment facility is too big, operating cost is excessively high.
Therefore, seek that facility investment is few, operating cost is low and the efficient large-scale pig farm biogas residue of processing, it has also become solve to support
Grow the key point of industry pollution.
Invention content
The technical problem to be solved in the present invention is to provide a kind of facility investment is few, operating cost is low and being capable of efficient process rule
The harmless processing of large-scale pig farm biogas residue of modelling pig farm biogas residue and utilization of resources technique.
