混合营养脱氮在低C/N工业废水处理中的研究进展
Research progress of mixotrophic system in industrial wastewater of low C/N ratio
摘要
Abstract
Since refractory nitrogen heterocyclic compounds in nitrogen-rich industrial wastewater aggravates the imbalance of carbon to nitrogen ratio and inhibits the nitrification and denitrification process in biological nitrogen removal process,exploring a new treatment process has become the inevitable course to efficiently treat low C/N industrial wastewater.Mixotrophic technology combines the metabolic pathways of heterotrophic and autotrophic nitrogen removal to optimize the nitrogen removal performance of low C/N industrial wastewater and further realizes the quality and efficiency improvement of low C/N industrial wastewater treatment.This paper reviews the mechanism,advance and influencing factors of Fe-mediated biological nitrogen removal,sulfur-mediated biological nitrogen removal and bacteria-algal symbiosis processes in mixotrophic nitrogen removal processes,and expounds the characteristics of the three processes and the applicability of different types of low C/N industrial wastewater.From the perspective of optimizing electron donor,acceptor and metabolic pathways,it is proposed to increase the electron capacity and the electron transfer rate,combining the electrochemical and coupling Fe-S system to enhance the collaborative metabolism,and improve the metabolic performance of pollutants.关键词
