中国火法铜冶炼污染物排放情景分析

Pollutants Emission Scenario Analysis of China's Copper Smelter Industry

基于目前中国火法炼铜的污染物产生特点,即冶炼过程中污染物产生差别主要体现在熔炼阶段工艺技术水平的高低,本文根据产业发展战略导向,对现行的熔炼工艺即先进熔池炉、闪速炉熔炼技术和传统鼓风炉熔炼技术设定情景:当2015年精炼铜产量达到500万t时,熔池、闪速、鼓风熔炼三种工艺的比重分别为:情景一50%、40%和10%,情景二60%、40%和0,情景三70%、30%和0。以2007年的冻结情景为基准,对污染物的产生量与排放量进行情景分析。结果表明,情景三是最优方案,在铜产量大幅增加的同时,通过工艺结构调整、促进废物资源化利用,基本可以实现主要污染物的排放不增加,这对火法炼铜行业污染物减排管理决策具有参考价值。

Based on the pollutants production of current copper smelter industry in our country that the pollutant produce difference is mainly from the various technologies adopted in melting process, among these the pool melting and flash smelting are advanced technologies and blast melting is being in disused technology. According to copper industry development plan to set scenarios in year 2015 year as below, when China refined copper production up to 500 thousand tons, the proportion of smelting technology of pool and flash and blast will be, scenario lst：50%, 40% and 10%, Scenario 2ed：60%, 40% and 0, Scenario Three： 70%, 30%. Compared the pollutants production and emission with that of the frozen status in year 2007, the results showed that the scenarios 3ed is the best program, when there is a substantial increasing in copper production while the pollutant total emission will not increase at the same time, which can be reached mainly through technology structure adjustment and promoting the waste resources comprehensive utilization. It is a significant reference for decision - making on pollutants emission reduction in copper smelter industry.
