Description

Technical Field

[0001] The present invention relates to the technical field of solid-liquid separation of livestock manure, and in particular to a solid-liquid separation device and method for livestock manure such as cow manure, pig manure and chicken manure. Background Art

[0002] Most livestock farmers in my country use direct water flushing to flush manure and urine. However, this method has the disadvantages of high water consumption and significant waste. In response to the requirements of new rural development and growing awareness of environmental protection and energy conservation, livestock farms are constructing biogas digesters and biochemical tanks to treat manure and urine. However, the manure entering the biogas digesters is not subjected to solid-liquid separation. In practice, this direct biogas production method has proven less than ideal. This is because untreated manure and urine entering the biogas digesters significantly increases the organic load per unit volume, requiring a significant increase in the digester's capacity. Long-term use of biogas digesters leaves behind a large amount of residue, which clogs the digesters, reducing their capacity and rendering them unusable. Cleaning the digesters is labor-intensive, unsafe, and increases costs. Directly selling fresh manure is also difficult to transport. Therefore, we have discovered that solid-liquid separation before digesting manure and urine can not only solve the problem of manure sedimentation in the digesters, significantly increasing their processing capacity, but also significantly reducing the construction area of ​​biogas and biochemical tanks. This saves construction investment and land area for environmental treatment. The separated solid manure can be directly used as fertilizer for fruit trees and forests and as a raw material for organic fertilizer. It can be sold to organic fertilizer factories as a raw material for organic fertilizer or used for self-production, achieving both social and economic benefits.
