大庆市养牛污染状况初步调查与减排能力研究

Preliminary Investigation on Pollution Status of Cattle Raising and Study on Emission Reduction Capacity in Daqing City

指出了随着国内养殖业的迅速发展,畜禽养殖业的污染问题也愈加严峻,因此,调查畜禽养殖的污染状况并提出合理建议具有较大的意义。通过调查大庆市及其周边地区养牛污染的情况,统计污染数据,根据《畜禽养殖业污染排放标准》上推荐的估算系数,计算了养牛污染物排放总量。以干撒式发酵床工艺为例,说明了养牛废水零排放的可行性,并据此对大庆市养牛废水的治理和利用提出了相关建议,为区域养殖废水的污染物减排给出了相关对策和措施。

With the rapid development of livestock and poultry industry in China,the pollution of livestock and poultry breeding is becoming more and more serious,which has a great impact on the environment.Therefore,it is of great significance to investigate the pollution status of livestock and poultry breeding and to put forward reasonable sugges-tions.The pollution of Cattle Industry in Daqing and its surrounding areas is investigated,and the pollution data are counted.According to the estimation coefficient recommended in the Standard of Pollution Discharge of Livestock and Poultry Industry,the total amount of pollutant emission of livestock and poultry is calculated.The feasibility of zero discharge of cattle wastewater was illustrated by the dry-scatter fermentation bed process.Some suggestions were put forward for the treatment and utilization of cattle wastewater in Daqing city,and some countermeasures and measures were put forward for the pollutant reduction of regional aquaculture wastewater.
