摘要
《城镇污水处理厂污染物排放标准》(GB 18918-2002)的实施对氨氮的排放浓度提出了更高的要求,我国许多城镇污水处理厂出水中氨氮难以符合标准,其中碳源不足成为主要的反硝化脱氮限制因素.本文针对低C/N比污水需要额外投加碳源以强化反硝化脱氮,总结了天然或改性纤维素、可生物降解性聚合物、多碳源复合材料的新型固体碳源的研究应用现状和存在问题.
Abstract
With the enforcement of the Pollutant Emission Standards for Urban Wastewater Treatment Plants(GB-18918-2002),which sets stricter limits on ammonia nitrogen emission concentrations,many urban wastewater treatment plants in China are struggling to meet the standards.The main obstacle to achieving denitrification is the insufficient supply of carbon sources.This paper summarizes the current status and problems in the research and application of new solid carbon sources of natural or modified cellulose,biodegradable polymers,and multicarbon composites for the purpose of enhancing denitrification and denitrification of sewage with low C/N ratios,which requires the additional addition of carbon sources.
