摘要
近年来,由于自养反硝化、甲烷氧化耦合反硝化等反硝化脱氮技术具有无需投加固/液态有机碳源和环境友好等特点,能有效处理低碳氮比含硝酸盐废水而受到广泛关注。阐述了基于铁、硫、氢气和甲烷为电子供体的新型反硝化脱氮工艺技术的研究进展,探讨其现有局限,并对今后的研究进行了展望。
In recent years,autotrophic denitrification,methane oxidation coupled denitrification and other denitrification nitrogen removal technologies have attracted extensive attention,due to no need for adding external solid/liquid organic carbon source and environmental friendliness,especially suited for treating low C/N nitrate-containing wastewater.This paper mainly describes the technical research progress of new denitrification process based on iron,sulfur,hydrogen and methane as electron donors,and discusses its existing limitations and prospects for future research.
