sbbr脱氮与人工湿地除磷联合工艺应用解析

强化 SBBR 脱氮与人工湿地除磷联合工艺的讨论 摘要：本文在总结国内外脱氮除磷工艺的基础上，提出了强化 SBBR 脱氮与人工湿地除磷联合工艺并建立、启动了该工艺的试验装置。SBBR 采纳新型两格交替运行形式，强化了碳源保存和同步硝化反硝化脱碳效率；人工湿地选种的植物为菖蒲和矮生百慕大草，以进一步去除 SBBR 出水中的磷。通过测试分 析 ， 该 工 艺 具 有 稳 定 的 脱 氮 除 磷 能 力 ， 氮 、 磷 的 去 除 率 分 别 能 达 到92%、91%，是一种新型的有效污水处理工艺。关键词 污水处理 脱氮除磷 SBBR 人工湿地 A combined process with enhanced SBBR for nitrogen removal and constructed wetlands for phosphorus removal ABSTRACT This paper gives a review on development of nitrogen and phosphorus removal processes in the world and proposes a combined process with enhanced SBBR for nitrogen removal and constructed wetlands for phosphorus removal. This SBBR operated alternately in two similar parts of the reactor to improve simultaneous nitrification and denitreification (SND). Calamus and Bermuda grass were planted in two constructed wetlands for further phosphorus removal. According to the experimental testing and analyzing, it demonstrates that the process has a good and stable nitrogen and phosphorus removal capability. The nitrogen and phosphorus removal rates reach 92%, 91%, respectively. This is a new type of effective wastewater treatment process.Key words wastewater treatment nitrogen and phosphorus removal SBBR constructed wetland 目录1 绪论..............................................................................................................................................11.1 氮、磷污染的来源及其危害.............................................................................................11.1.1 氮、磷污染的来源及其影响因素..........................................................................11.1.2 氮、磷污...
