In recent years, with the development of economy and the improvement of living standard of people, the demand of livestock and poultry products is continuously increased, the living scale is continuously enlarged, the livestock and poultry breeding mode in China is changed from the breeding of each household to the large-scale intensive breeding, the intensive degree is developed to a quite high level, and a large pig farm breaks through 50 multiplied by 104100X 10 poultry farm4Feather is obtained. With the continuous expansion of production scale, the pollution caused by the discharged excrement is more serious. The national environmental protection administration carries out the large-scale livestock and poultry breeding pollution condition investigation on 23 provinces, autonomous regions and direct municipalities in China, and the results show that the large-scale livestock and poultry breeding pollution presents three outstanding problems: firstly, the excrement discharge amount is large; secondly, the spread of livestock and poultry pollutants is wide and the harm is large, and the COD discharge amount of the livestock and poultry excrement is far more than the sum of the discharge amounts of industrial and domestic sewage; and thirdly, presenting more serious ecological pressure.
The contents of organic matters, nitrogen, phosphorus and potassium in the livestock and poultry manure are very rich, and the utilization value is very high; however, the chemical fertilizers mainly used today cause soil hardening and salinization. In conclusion, how to utilize the livestock and poultry manure to inhibit the pollution of the livestock and poultry manure to the environment and replace chemical fertilizers seriously polluting the environment as crop nutrition sources is a problem with high research value.
