冶金三废的污染及治理

Pollution and Treatment of Metallurgical Wastes

冶金工业主要由烧结、炼铁、炼钢、轧钢等工艺组成。在商品生产过程中,会产生大量“废弃物”即各种化学物质,且它们会进入环境而导致污染。鉴于此,从冶金废水分类、轧钢和炼铁废水的处理方面对冶金废水进行了阐述,从钢铁工业废气的危害及废气的处理方面对冶金废气进行了描述,最后阐述了废渣的分类及其处理。

The metallurgical industry mainly consists of sintering,ironmaking,steelmaking,rolling and other processes.In the process of commodity production,a large number of"wastes",namely various chemical substances,can be produced,which enter the environment and cause pollution.In view of this,the metallurgical waste water is described from the classification of metallurgical waste water,the treatment of steel rolling and ironmaking waste water,the harm of steel industry waste gas and the treatment of waste gas,and finally the classification and treatment of waste slag are described.
