摘　　要：本文介绍一种新的现代化的除去炼焦厂废水中PAH的方法,其PAH的脱除率达95%以上,此法采用木粉真空过滤装置,吸附后的木粉及有机废物直接再循环至炼焦配煤中,故无废物产生。此法由荷兰Hoogovens炼焦厂1984年开始开发研究,1991年获得工业应用。This paper introduces a new modern efficient method for remoying PAH from coke oven waterwaster, the PAH removal—efficiencies above 95% can be achieved. The polluted wood flour and organic material is recycled directly to the coal blend so no extra waste is produced. This method development at Hoogovens is started in 1984 and is achieved on industrial application in 1991 in the Netherlands.
