摘要
硫自养反硝化是一种具有低碳、低费、低污泥产量优势的脱氮技术。文章介绍了基于不同电子供体、pH、溶解氧(DO)和水力停留时间(HRT)等因素对硫自养反硝化反应效率的影响并对比了不同工艺的优缺点,阐述了硫自养反硝化工艺中微生物的群落特征,提出了现阶段存在的不足与缺陷,最后对其未来应用进行展望。
Sulfur autotrophic denitrification is a nitrogen removal technology with low carbon,low cost and low sludge yield.This paper introduces the influence of different electron donors,pH,dissolved oxygen(DO)and hydraulic residence time(HRT)on the efficiency of sulfur autotrophic denitrification,and compares the advantages and disadvantages of different processes in detail.It also describes the characteristics of microbial community in the sulfur autotrophic denitrification process,and proposes the deficiencies and defects at present stage.Finally,the future application of this technology is prospected.
