摘要/Abstract

摘要： 固相反硝化是一种新型的异养反硝化工艺，采用固体有机物同时作为反硝化微生物的碳源和生物膜载体，可用于地下水和低C/N比污水的脱氮处理。固相反硝化系统生物膜的微生物群落结构决定固体碳源的降解效率，进而决定反硝化脱氮的速率和系统的稳定运行。因此，微生物群落结构的研究对于固相反硝化工艺的优化以及反应机理的解析具有重要意义。对不同固相反硝化系统微生物群落结构的研究现状和进展进行了综述，并探讨了当前研究中存在的问题和发展趋势。

Abstract: Solid-phase denitrification（SPD）is a new type of heterotrophic denitrifying process, in which solid organic matters are used simultaneously as carbon source and biofilm support. SPD process has been applied on nitrogen removal from groundwater and wastewater with the low ratio of carbon to nitrogen. Microbial community structure in SPD system determines not only degradation efficiency of solid carbon source but also denitrification rate and stable running of the SPD system. Therefore, the research on microbial community structure is significant for the optimizing SPD process and exploring its mechanism. This review summarized the present research status and progress on microbial community structure in different SPD systems. In addition, the main problems and the new perspectives in the present study were also discussed.

Key words: solid-phase denitrification, nitrate, biofilm, microbial community
