基于监测数据的规模化畜禽养殖面源污染总量测算研究

Study on Estimation of Non-point Source Pollution on Large Scaled Livestock and Poultry Farm Based on Monitoring Data

随着我国规模化畜禽养殖业的发展,畜禽养殖面源污染已超过工业源和生活源污染,成为最大的污染源,也成为"十二五"污染减排的重点。本文从规模化畜禽养殖面源污染影响因素分析着手,提出基于监测数据的"产生-削减-面源体现系数法"的畜禽养殖面源污染总量测算方法,并给出了计算公式和总量测算流程,最后以内江市规模化畜禽养猪场为例,介绍了总量测算过程,给出了内江市规模化养猪场面源污染总量。

With the development of large sealed livestock and poultry husbandry in China, the non-point source pollution of livestock and poultry husbandry has already exceed the pollution from industrial source and domestic source, which becomes the largest pollution source, correspondingly the key point of poUution discharging reduction during the 12th Five Year Plan. In this paper, based on the analysis of factors affecting non-point source pollution from large scaled livestock and poultry husbandry, a method, Non-point Source Reflect Coefficient Method, was propose to estimate the total amount of non-point source pollution of livestock and poultry husbandry according to the monitoring data, and the calculation formula and the estimation procedure were presented. Finally, a case study was analyzed on a large scaled pig farm in Neijiang City including the calculation procedure of total pollution amount and the calculation result.
