污水厂反硝化传统及可供替代碳源研究进展

Research progress of traditional and alternative carbon sources for denitrification in wastewater treatment plants

关于可供替代外碳源的研究引起了许多学者和从业人员的关注,以期发现或研发出新碳源弥补传统碳源在实际应用中的不足。综述了传统碳源在实际应用的局限及在实验室研究中的潜在问题和可供替代碳源的研究发展现状及其作为反硝化碳源的优劣势,并在此基础上对传统碳源和可供替代碳源建立了相关评价体系,为污水厂选择适合自身的外碳源提供参考。指出污水厂外碳源的研发趋势主要包括新物质开发,复合碳源研发和废物(液)预处理工艺的改进。

In order to discover or develop new carbon sources to cover the deficiency of traditional carbon sources,alternative carbon sources have attracted the attention of scholars and practitioners.This paper reviews the limitations and potential problems of traditional carbon sources in practical application and laboratory researches,and research status and advantages or disadvantages of alternative carbon sources for denitrification;also,an evaluation system of traditional and alternative carbon sources is established to provide reference for WWTPs to select suitable external carbon sources.The trends of research and development on external carbon sources in WWTPs are pointed out,including development of new materials or compound carbon sources and improvement of waste pretreatment process.
