摘要
燃煤电厂汞污染已经成为继SO2污染之后的又一重大污染问题。燃煤烟气中汞污染的控制研究是目前重要的环保课题之一,开发高效、低成本、无二次污染的烟气脱汞技术已成为研究重点。本文综述了国内外在汞的监测方法、汞在燃煤电厂中的迁移规律以及汞污染物控制措施等方面的研究进展,并做了简要的分析与总结,对未来燃煤烟气汞污染控制技术的发展进行了展望。
Following after sulfur dioxide pollution,mercury pollution during coal combustion is thought to be another big pollution problem.Developing technologies for mercury control will be one of the important environmental protection issues in the electric power industry.At present the development of efficient low-cost and no secondary pollution of mercury control technology is the focus of researchers.The paper showed the measurement approached of mercury and its speciation concentrations for flue gas in coal-fired power plants.It also analyzed the regularity of migration and transformation of mercury,the form of mercury and the main factors which affected the elimination rate of mercury.The latest research progress of mercury emission control was summarized.Some concerned study was reviewed,with prospective on the mercury control technology for coal-fired power plants.
