畜禽养殖废水甲烷化、反硝化和厌氧氨氧化除碳脱氮探讨

Discussion on Carbon and Nitrogen Removal by Methanogenesis,Denitrification and Anammox Processes for Livestock Wastewater Treatment

甲烷化、反硝化和厌氧氨氧化均是实现养殖废水除碳脱氮的途径,与传统除碳脱氮相比,三者联合作用途径占地面积小、运行费用少、能源消耗低、污泥产量少,在养殖废水处理中有着十分广阔的应用前景。文中介绍了甲烷化、反硝化和厌氧氨氧化反应机理;分析了厌氧氨氧化、甲烷化、反硝化脱氮效果和稳定运行的影响因素及其耦合可行性;论述了目前甲烷化、反硝化和厌氧氨氧化的耦合研究;提出了后期对甲烷化、反硝化和厌氧氨氧化用于养殖废水处理研究的展望。

Methanogenesis,denitrification and anammox are processes that can achieve carbon removal and nitrogen removal,which has advantages such as small footprint,low operating costs,low energy consumption and less residual sludge,compared with traditional biological nitrogen removal process.So that it has a very wide application prospects.In the article,reaction mechanism of methanogenesis,denitrification and anammox is introduced.Influencing factors of anammox,methanation,denitrification and its coupling feasibility are also discussed.Then coupling research of methanogenesis,denitrification and anammox are discoursed.At last,further research of methanogenesis,denitrification and anammox in livestock wastewater is proposed.
