Pollution Producing Coefficient Study of Scale Livestock and Poultry Farming

As livestock and poultry farming was being scale,the pollution of livestock and poultry farming already became the most important pollution source in countryside.In this paper,the wastewater and solid waste as produced by livestock and poultry farming was chosen as monitoring objects to study the pollution producing coefficient.Thereafter,the calculation method of pollution producing coefficient for per unit livestock and poultry from birth to slaughter was obtained.Finally,taking Neijiang City for example,the pollution producing coefficients for different size scale pigs farms in different season were calculated,the findings were also compared with the first census data of pollution source.
