摘要
硝酸盐污染已成为最重要的水质问题之一,低碳氮比废水在深度脱氮方面面临碳源不足的问题,自养反硝化无需有机碳源,以低成本、污泥产量少的优势受到广泛关注和研究。综述了近些年来硫铁矿自养反硝化工艺在去除废水中硝酸盐方面的研究,介绍了其自养反硝化时的微生物特点,并阐述了该工艺及其协同其他工艺的研究进展,阐明其潜力与局限性,以期为基于硫铁矿自养反硝化处理废水的进一步研究与应用提供理论依据。
Nitrate(NO,)poses a significant threat to water quality,emerging as a crucial pollution concern.Additionally,low C/N ratio wastewater faces challenges due to a shortage of carbon source.Autotrophic denitrification has garnered attention and research interest for its advantages,including no need for external carbon source,low cost and low sludge yield.In this review,we provide an overview of recent research progress in pyrite autotrophic denitrification processes and technologies for the systematically removal at NO,-containing wastewater system.The microbial characteristics in pyrite autotrophic denitrification are analyzed.In addition,the research progresses of the pyrite autotrophic denitrification technology are summarized,including multiple cooperative processes,potential and limitations.Ultimately,this review aims to offer novel insights and a theoretical foundation for achieving efficient wastewater treatment.
