Research on Denitrification Efficiency and Process of Artificial Wetlands with Sulfur Autotrophic as the Core Filler
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.
