抚仙湖径流区畜禽养殖污染防治工程实施前后污染负荷研究

Comparative Research of Pollution Load from Livestock Raising Farm before and after Implementing the Pollution Control Projects in the Fuxianhu Lake Watershed

通过对抚仙湖径流区畜禽养殖场的调查,选取6个养殖场为代表,研究畜禽养殖污染防治工程实施前后污染负荷情况。研究结果表明,6个生猪养殖场每年可削减COD 95.86t,BOD 93.61t,TN16.24t,TP 6.12t,NH3-N 7.80t,污染防治效果显著。

Six livestock raising farms were investigated to compare the changes of pollution load before and after im-plementing the pollution control projects in the Fuxianhu Lake watershed.The results showed that the projects could reduce 95. 86 tons of COD,93. 61 tons of BOD,16. 24 tons of TN,6. 12 tons of TP,and 7. 80 tons of NH3 -N each year,which has implied a significant effect of pollution prevention.
