Thing fermentation technical field.
Background technology
Livestock and poultry breeding industry is China's rural economy strong industry, and livestock and poultry farms in scale turns into main body, while also brings
Serious pollution problem, biogas engineering are the most effective solutions that livestock and poultry farm waste pollution is administered, biogas engineering
With the energy, ecology and the preferable comprehensive benefit of economic dispatch, all kinds of organic waste degradings are handled simultaneously using anaerobic digestion techniques
The system engineering equipment of clean energy resource biogas is produced, organic matter is decomposed into methane, titanium dioxide by it using anaerobe activity
Carbon and water, material is set to obtain minimizing, the processing disposal of stabilisation, recycling.Meanwhile rural area cultivation rice, corn, wheat production
Raw substantial amounts of stalk, agricultural crop straw turn into the new source of Rural Plane Source Pollution, are burned in field, generate a large amount of dense cigarettes
Mist, rural area and urban environment are influenceed, improve the comprehensive development and utilization of agricultural crop straw, one promotes the stalk renewable sources of energy, especially
It is bio-fuel, second, the deficiency of feces of livestock and poultry raw material in production and use of marsh gas fermentation can be directed to, improves methane-generating pit utilization rate, be
It is single and insufficient to make up biogas fermentation material, is mixed using stalk with feces of livestock and poultry as fermentation raw material, can so solve current
Anaerobic fermentation raw material problem.
At present, in feces of livestock and poultry mixed stalk raw material anaerobic fermentation actual moving process in the prevalence of material concentration it is low,
