Study On Characteristics And Laws Of Pollutant Emission Of Livestock And Poultry Sources In Anhui Province

At present, the livestock and poultry pollution has become the main way of agricultural non-point source pollution.The pollution is one of the most serious pollution in important basin.Through theoretical analysis and typical monitoring,this article concludes laws of the livestock and poultry pollution change.1, the producing pollution’s coefficient of beef cattle, monitoring results from the producing pollution’s coefficient for total N25.02g/head. Days, total P0.59g/head. Days, organic matter45.44g/head. Days, copper0.1g/head. Days, zinc4.29g/head. Days, COD180.65g/head. Days, ammonia nitrogen13.19g/head. Days, including total N, organic matter, COD, the producing pollution’s coefficient of total P high producing pollution coefficient relatively low.2, cows, monitoring results from emission coefficient for the total emission coefficient cow13.12kg/head.--total P35.37kg, heaven. Days, organic matter/head1826.53g/head. Days, copper305.65mg/head. Days, zinc738.12mg/head. Days, COD4.16kg/head. Days, ammonia nitrogen0.71kg/head. Days, including the total P in all pollutants emission coefficient of total was the highest, N.3, pig sewage coefficient, the utilization rate of breeding pig feces for100%, sewage discharge coefficient of total N and total P, organic matter, total k are equal to zero, every other pollutant emission coefficient k g0.13respectively COD/head. Days, ammonia nitrogen0.02kg/head. Days, CHP nitrogen for0.04kg/head. Days, copper0.01mg/head. Days, zinc0.11mg/head. Days, relative cows speaking were lower. This is mainly because in feeding process of feed, and every fed produced and collecting the excrement and urine volume caused by different.4, layers, layers farmed in emission coefficient in the process of collecting dung also are all use, total N, organic matter, total k emission coefficient of all zeros, COD in each index of highest emission coefficient for4.43g/head. Days, followed by CHP nitrogen of1.97g/head. Days, ammonia nitrogen for0.31g/head. Days, total P for0.12g/head. Days, cu, zn pollution discharge coefficient5.04mg/head respectively. Days,38.51mg/head. Days.5, chicken emission coefficient, chicken in feeding process for100%, the utilization rate of feces emission coefficient of total N, organic matter, total amount of k for zero emission coefficient of the COD, for14.49g/head. Days, CHP nitrogen pollution coefficient is3.95g/head. Days, copper, zinc drainage coefficients were1.79mg/head. Oh,33.88mg/head. Days, is relatively low.The results of this study comprehensive accurate brought ChuQinYe pollution province mainly accomodations pollutants, this paper analyzes the dynamic change trends emissions rules and for the correct evaluation ChuQinYe pollution sources pollution with basic parameters for future agricultural non-point source pollution control, and provide scientific basis for the environmental management scientific and government to make the rural environment protection policies, energy efficiency indicators provide basis for decision-making.
