Technical field
The invention belongs to the process field that livestock and poultry cultivation excrement is dirty.It is related to a kind of biogas dry fermentation device and efficient anaerobic system
System, is a kind of integrated treatment for cow manure method and apparatus of livestock and poultry farm based on dry cleaning up excrement, is specifically to be entered with excrement dirt for raw material
The method and apparatus of row anaerobic fermentation processing, can be achieved treatment for cow manure.
Background technology
In recent years, expanding economy accelerated the development of livestock and poultry breeding industry, thereby produced substantial amounts of feces of livestock and poultry, not only
Environment is polluted, the sustainable development of aquaculture is also influenceed.The breeding production of current scale in the highest flight, these plants
Treatment for cow manure technique is particularly important.
At present, divide in the way of plant's cleaning up excrement, mainly there is water to rush excrement and dry cleaning up excrement two ways.Dry cleaning up excrement mode
Mainly excrement is shunted after producing, and argol is by mechanically or manually cleaning and collecting, and urine and flushing water then flow out from sewer, point
Do not handled.Dry cleaning up excrement mode is low with the solid-state excrement water content collected, and nutrient component damages are small in excrement, manurial value
Height, is easy to During High-Temperature Composting or carries out other modes processing utilization；Water consumption is few, and the sewage quantity of generation is few, and the pollution in sewage
Thing content is low, it is easy to the advantage such as purified treatment, therefore has turned into the major way of China's scale livestock farming cleaning up excrement.
However, presently disclosed patent is handled for feces of livestock and poultry and sewage respectively.Application No.
