摘要
传统生物反硝化受限于废水中碳源的不足导致总氮去除率低,在实际处理中需要额外投加碳源.硝酸盐依赖型亚铁氧化(NDFO)作为一种经济且无二次污染的自养反硝化技术,可有效应对进水碳源不足的问题.本文总结了NDFO反应原理与NDFO功能微生物,通过阐述乙酸盐对NDFO的影响以及NDFO与Feammox的耦合,综述了NDFO的脱氮强化措施.
Abstract
Conventional biological denitrification is limited by the insufficient carbon source in the wastewater,resulting in low total nitrogen removal,and additional carbon sources need to be added in the actual treatment.Nitrate-dependent ferrous oxidation(NDFO)as an eco-nomic and secondary pollution-free autotrophic denitrification technology,can effectively deal with the problem of insufficient carbon source in the influent water.This paper summa-rizes the reaction principle of NDFO and the functional microorganisms of NDFO,and re-views the nitrogen removal enhancement measures of NDFO by elaborating the effect of ac-etate on NDFO and the coupling of NDFO and Feammox.
