摘    要:根据2009年云南省铅锌冶炼行业的特点以及SO2排放情况,在大量数据收集和实地调研的基础上,采用实测法与物料衡算法相结合核算出云南省铅锌冶炼行业SO2产排污系数,同时给出铅锌冶炼行业不同工艺和规模下的SO2产排污系数。此外,将该研究核算结果与《第一次全国污染源普查工业污染源产排污系数手册》和《主要污染物总量减排核算细则》(试行)中的标准进行比较。研究结果表明:云南省铅冶炼行业SO2产污系数(以粗铅计)为333.04 kg/t,排污系数为63.90~77.49 kg/t;锌冶炼行业SO2产污系数(以电锌计)为570.43 kg/t,排污系数为8.46~19.54 kg/t;造成系数差异的主要原因是全国平均水平与云南省原、辅材料及能源消耗、工艺情况、治理措施不同。

Abstract: Considering the characteristics of lead and zinc smelting industry and SO2 emission of Yunnan Province in 2009, and on the basis of large quantities of investigated data, a measurement method and mass balance were used to calculate SO2 emission factors of lead and zinc smelting industry. The coefficients of SO2 producing and discharging under specific process were also given. Moreover, the emission factors were compared with the discharge coefficients of industrial pollutants in the First National General Survey of Pollution Sources and Total Pollutant Emissions Rules (Trial Implementation). The results show that the coefficient of producing pollution for zinc smelting industry (count by crude lead) is 333.04 kg/t, and the coefficient of discharging pollution is 63.90-77.49 kg/t. For zinc smelting industry, the coefficient of the producing pollution (count by zinc) is 570.43 kg/t, and the coefficient of discharging pollution is 8.46-19.54 kg/t. The cause of coefficients differences are mainly due to the gap between national average level and that of Yunnan Province in the aspect of original and auxiliary materials, resources consumption, process conditions, and control measures.
