锑冶炼行业Sb、Pb、As环境空气质量影响预测与评价

锑冶炼行业Sb、Pb、As环境空气质量影响预测与评价(10200字)
摘  要：我国是世界上锑矿资源最为丰富的国家，总保有储量为27万t，居世界第1位，锑矿的储量占世界的66.2%。锑冶炼行业在生产过程中会排出大量含污染物的烟气，尤其是烟尘中所含的重金属元素，如Sb、Pb、As等，对环境影响较大。根据大气监测结果可得出污染物本底值，同时根据其生产工艺计算出相应的烟气量、排放强度等数据。再结合实际地理气象条件和地形条件，利用EIAA大气评价助手软件对其分别进行高斯点源模式和熏烟模式两种条件下的环境影响评价，预测污染物排向周围环境中的最大落地污染浓度及影响范围，参照国家相关标准，以此做出冶炼厂废气中排除的重金属元素对环境空气质量影响的相应评价。

Prediction and Evaluation of Sb, Pb, As's Impact on Environmental Air Quality in Antimony Smelting Industry
Abstract: China has the richest antimony resources in the world, total reserves to 27 milliont,the amount of antimony ore acount for 66.2% in the world. It can conclude the backgroundvalues of pollutant according to the result of atmosphere monitorating. And calculate the corresponding flue gas, effluent strength and some data according to its production processes at the same time. Value the impact on the environment through the EIAA of gaussian point source mode and smoked mode with the actual geographical conditions and meteorological conditions. Forecast the largest concentration of landing and the biggest landing influence scope about the surrounding environment which affected by pollutant. And referencing to the relevant national standards, make a assessment about the the environment quality, which affected by metal elements out from metallurgical plant.     Keyword:Sb；antimony smelting；atmospheric monitoring；quantity ；largest concentration of landing
