| 摘 要： | 在城市污水再生全流程理念指导下,分析了目前较为实用的几种污水再生工艺,阐述了硝化-反硝化和厌氧氨氧化两种生物脱氮途径的机理,并进行了对比分析,提出了以厌氧氨氧化为主体生物脱氮单元的城市污水的再生全流程新思路。城市污水再生全流程不但在各自的单元中实现了TOC,TN和TP去除的优化,而且在生物脱氮单元中,根据含氮废水的水质和物理特性实现了污泥消化液脱氮和主体二级处理水脱氮的优化。

| Abstract: | Under the concept of complete flow scheme for municipal wastewater reclamation,several practicable processes of municipal wastewater reclamation at present were analyzed and contrasted based on the mechanisms of two microbiological nitrogen removal processes of nitrification-denitrification and anammox.At last,a new concept of complete flow scheme for municipal wastewater reclamation was put forward,which would mainly remove nitrogen via anaerobic ammonium oxidation process.The new complete flow scheme for ... |
