规模化畜禽养殖产污系数研究

随着畜禽养殖逐渐走向规模化，畜禽养殖污染已成为农村污染的重要来源。以规模化畜禽养殖产生的废水和固体废弃物为监测对象，对规模化畜禽养殖产污系数进行研究，给出单位畜禽从出生到出栏的产污系数计算方法。以四川省内江市为实例，计算了不同季节、不同规模的规模化养猪场产污系数，并与第一次污染源普查数据进行比较。

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.
