摘要

氮氧化物(NOx)和汞(Hg)是燃烧烟气中常见的共存污染物。大气中汞和氮氧化物的排放不断增加，造成了相当大的环境风险。传统的烟气脱硫和脱硝技术存在许多社会经济、技术和环境方面的缺陷。生物技术可能是一种有前途和前景的替代战略。本文论述了烟气中汞和NOx生物脱除的理论基础(生物化学和基因组学基础)和技术潜力(h0生物氧化耦合反硝化)，并总结了近年来的实验和技术进展。最后，提出了几个具体的技术视角，以更好地指导未来的研究。

Biological treatments of mercury and nitrogen oxides in flue gas: biochemical foundations, technological potentials, and recent advances.

Nitrogen oxides (NO_x) and mercury (Hg) are commonly found coexistent pollutants in combustion flue gas. Ever-increasing emission of atmospheric Hg and NO_x has caused considerable environmental risks. Traditional flue gas demercuration and denitration techniques have many socioeconomic, technological and environmental drawbacks. Biotechnologies can be a promising and prospective alternative strategy. This article discusses theoretical foundation (biochemistry and genomic basis) and technical potentials (Hg⁰ bio-oxidation coupled to denitrification) of bioremoval of Hg and NO_x in flue gas and summarized recent experimental and technological advances. Finally, several specific technical perspectives have been put forward to better guide future researches.
