Research Progress on Treatment and Resource Utilization Technology of Manure and Sewage in Dairy Farm

The manure and sewage produced in dairy farm which are directly returned to the field or discharged without treatment not only result in environmental pollution,but also affect the sustainable and healthy development of the dairy industry.Using the physical form as the classification foundation of the manure and sewage,this paper summarizes the main harms brought by the improper disposal of manure and sewage in dairy farm,and expounded the scientific treatment and resource utilization technology of manure and sewage in dairy farm,including solid manure treatment technology,sewage treatment technology,microbial fermentation bed technology and utilization of the disposal products.Furthermore,we analyze the existing problems in treatment and resource utilization technology of manure and sewage in dairy farm and the developmental direction in future,in hoping to provide references for improving the level of scientific treatment and resource utilization of manure and sewage in dairy farm.
