煤化工过程的主要污染物及其控制

介绍了煤化工过程产生的主要污染物及其排放特征,综述了当前各类污染物的控制方法 ,特别是焦化废水的处理方法,提出了新的工艺集成思路。新的煤化工发展应降低能耗并减少环境污染,污染控制工艺应更加生态化,降低二次污染。

Primary Pollutants and Pollution-control Principles in Coal Chemical Industry

The primary pollutants from coal chemical industry （CCI） and their emission characteristics were present- ed with reference to coal quality, process requirement, technical characteristics, operation procedure, etc. A new integrated process approach was suggested based on the present control methodologies of different pollutants from coal chemical in- dustry, the treatment of coking wastewater in particular. The future development of CCI should be established on both en- ergy conservation and pollutants reduction. Moreover, the procedure of pollution control should be more ecotypic and less secondary pollution to meet stricter environmental safety requirements.
