摘　　要：炭素厂用作粘结剂及浸渍剂的煤沥青或焦油在制糊、焙烧等工序中产生大量的沥青烟,直接排放会造成工作环境及大气污染,根据产品品种不同所产生的其他污染物不同分别采用焚烧法、吸附法及静电捕集法,其中焚烧法对所有有机碳治理最为彻底,是今后的发展方向。Coal tar pitch and coal tar are widely used in carbon plants as binding or impregnating agents.Large quantity of pitch fume is generated from various manufacturing process such as paste mixing and baking,etc.It will severely pollute the working environment and atmosphere if it isn＇t scrubbed.Normally incinerating,absorpting and electrostatic precipitating method are used in scrubbing system according to different processes and other pollutants in the fume.The incinerating method can thoroughly clean the VOC（volatile organic carbon）,and will be the available method in the future.
