Abstract

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
