摘要:
为控制严重的水体富营养化问题，满足日趋严格的污水排放标准，污水厂在利用生物反硝化技术进行深度脱氮时大多需要投加外碳源。常见的外碳源可分为液体碳源与固体碳源两类，其中固体碳源近年来引起了国内外的广泛关注。系统总结了固体碳源的物质类型，阐述了固相反硝化系统释碳与脱氮的相关原理，综述了近年来固体碳源在污水深度处理中的应用研究进展，并基于上述内容提出了对固体碳源未来研究的展望。相较于液体碳源，固体碳源既是反硝化过程持续的电子供体，又可作为生物膜生长的载体，相关工艺简单易于控制，脱氮效果稳定，为未来污水深度处理技术的发展提供了一条新思路。
Abstract:
In order to control serious water eutrophication and meet increasingly stringent sewage discharge standards, it is need to add external carbon source when using biological denitrification technology for advanced nitrogen removal in sewage treatment plants. Common external carbon source can be divided into liquid carbon source and solid carbon source. Solid carbon source has attracted widespread attention at home and abroad in recent years. This paper systematically summarizes the material types of solid carbon source, expounds the relevant principles of carbon release and nitrogen removal in the solid-phase denitrification system, summarizes the current application research progress of solid carbon source in advanced sewage treatment, and puts forward the prospect for future research on solid carbon source based on the above content. Compared with the liquid carbon source, the solid carbon source is not only a continuous electron donor for the denitrification, but also a carrier for the growth of the biofilm. The process system is simple and easy to control, with stable denitrification efficiency. The solid carbon source provides a new idea for the development of advanced sewage treatment technology.
