曝气生物流化床处理高氨氮粪便污水
Keywords: 曝气生物流化床反应器 ,同步硝化反硝化 ,氨氮
Abstract:
应用好氧曝气生物流化床反应器处理动车集便器粪便污水，研究反应器同步硝化反硝化脱氮及去除COD效能，以及DO对处理效能的影响，通过镜检观察反应器内微生物特性，探究反应器同步硝化反硝化脱氮机理。结果表明，反应器维持DO在2.5mg/L左右时，对粪便污水中氨氮、TN和COD的去除率分别达99.8%、84.1%和95.5%，在好氧曝气生物流化床反应器中，实现同步硝化反硝化脱氮并去除有机物。分析认为，反硝化脱氮主要发生在生物膜内的厌氧微环境，反硝化反应主要由厌氧反硝化菌完成，曝气生物流化床反应器同步硝化反硝化脱氮机理主要从微环境理论解释。
