摘要

An analysis methodology to determine heavy metal emission based on the whole product process was developed. In this article, the smelting technology and the raw materials components of the secondary copper smelting were introduced to analyse the amount of lead waste the site create per year. The balance of lead element gave the kinds and quantity of the waste including lead element clearly. The dust removal projects showed the smoke treatment efficiency. Thus, the atmospheric lead emission was finally determined from the whole process analysis method. Moreover, the discharge scheme is also significant to reduce the atmospheric pollution impact. There were two processes to choose the better smoke discharge scheme for the secondary cooper site. First, it determines whether the discharge schemes meet the national requirements of building chimney height. Then, the atmospheric dispersion model AERMOD has been used to predict the air environmental impact of the two schemes. The hourly concentration contribution data in 2009 were predicted. The results indicated that one-chimney scheme could reduce the lead pollution contribution value at 8–20%. Additionally, the model simulation could give the intuitive lead contribution distribution to judge the environmental impact.
