摘　　要：基于现有研究已知硫自养反硝化作为一种无需外加碳源、出水无二次污染的技术,对于低C/N比值污水脱氮效果好,在此情况下,研究者们开发出了硫自养核心填料技术产品,这种新型填料能够作为缓释型电子供体驱动自养反硝化微生物脱氮。该填料目前主要应用于市政污水、工业废水的处理中,本文主要讨论了硫自养滤料在人工湿地的应用研究,通过设置实验装置,模拟人工湿地运行方式,研究以硫自养为核心填料在人工湿地的脱氮效果,及确定最适于硫自养核心填料湿地的潜流类型、进水方式,为后续工程应用提供理论依据。Based on existing research,it is known that sulfur autotrophic denitrification is a technology that does not require additional carbon sources and has no secondary pollution in the effluent.It has good denitrification effects on low C/N ratio wastewater.In this case,researchers have developed a sulfur autotrophic core filler technology product,which can serve as a slow-release electronic donor to drive autotrophic denitrification microbial denitrification.This filler is currently mainly used in the treatment of municipal sewage and industrial wastewater.This article mainly discusses the application research of sulfur autotrophic filter media in artificial wetlands.By setting up experimental devices,simulating the operation mode of artificial wetlands,studying the denitrification effect of sulfur autotrophic core filler in artificial wetlands,and determining the most suitable subsurface flow type and inlet method for sulfur autotrophic core filler wetlands,theoretical basis is provided for subsequent engineering applications.
