一、调查点概况及调查方法调查点在德兴县308厂冶炼铅铜车间,立地为海拔40—90米的山谷地带,全年平均气温17℃,雨量1767毫米,≥5.0毫米的雨日80天。雾日18天。该车间1966年建立后采取旧烧焦鼓风流程,烟囱高度20米。据1 982年监测结锅烟气中二氧化硫的排放量,平均每台25.4公斤/时,即22,378,206标准立方米干气重/时,七台结锅总排放量为177.8公斤/时。从1 966年建厂起,烟气中有1—5/1000的二氧化硫
Survey point survey and survey method Dexing County, 308 factory smelting lead-copper workshop, site for the 40-90 m above sea level in the valley, the annual average temperature 17 ℃, rainfall 1767 mm, ≥ 5.0 mm rainy day 80 day. Fog day 18 days. The workshop was built in 1966 after the establishment of the old process of burning air blast, chimney height of 20 meters. According to the monitoring of sulfur dioxide emissions from fumigation fumes in 1982, the average emission of sulfur dioxide per kilogram was 25.4 kg / hour, that is, 22,378,206 standard cubic meters of dry gas weight / hour. The total emission of seven cookers was 177.8 kg / h. Since 1966, there are 1-5 / 1000 of sulfur dioxide in the flue gas
