Abstract: Based on manure separation technology for livestock enterprises, an automatic solid-liquid separation manure cleaning system has been designed for manure separation treatment and odor emission in slaughter waiting area of large and medium-sized slaughterhouses by adopting a combined process method integrating slatted floor and dry manure removal．Taking a livestock and poultry meat cold chain reserve project in Guizhou Province as an example, calculations and analysis were conducted on electricity and water savings, organic pollutant reduction, and corresponding CO₂ emissions reduction in slaughter waiting area．Research results indicated that this technology could reduce sewage discharge in waiting area by more than 60%, organic pollutant emissions by more than 60%, and odor emissions by more than 50%．It has achieved significant social and ecological benefits through electricity and water savings, carbon reduction, and environmental protection．
