| Abstract: |
| Animal husbandry has developed rapidly with the continuous economic development of China. Consequently, large amount of livestock and poultry manure has been generated, resulting in increasingly serious environmental pollution. Based on the livestock and poultry breeding data(large-scale livestock, pig, cattle, sheep, and poultry)of China in recent years and through the quantitative assessment of pollution, this paper concludes that different breeding methods lead to significant differences in the proportion of COD, TN, and TP loads of livestock and poultry pollution. This paper analyzes and summarizes the characteristics of the typical treatment method and resource utilization technology of livestock and poultry manure and provides decision support for pollution control. Based on a systematic assessment of the potential of livestock and poultry manure resources in China, we believe that their energy potential in our country is considerable. The use of livestock and poultry manure resources can meet the demand for nitrogen and phosphate fertilizers to a greater extent and reduce the harmful effects of excessive application of fertilizers to farmland soil. |
