anaerobic-anoxic-oxic读法"anaerobic-anoxic-oxic"的读法可以分解为三个部分: 1. "anaerobic"(无氧):[ˌænəˈroʊbɪk] 2. "anoxic"(缺氧):[ˌænˈɒksɪk]或[ˌeɪˈnɑːksɪk] 3. "oxic"(富氧):[ˈ
AAO法又称为A2O法,是英文Anaerobic-Anoxic-Oxic 第一个字母的简称(厌氧-缺氧-好氧),这是一种常用的污水处理工艺,可用于二级污水处理或三级污水处理,以及中水回用,具有良好的脱氮除磷效果,通过厌氧过程使废水中的部分难降解有机物得以降解去除,进而改善废水的可生化性,并为后续的缺氧段提供适合于反硝化过程的碳源...
A2O工艺(Anaerobic-Anoxic-Oxic)是一种通过厌氧、缺氧、好氧三阶段协同作用的生物处理技术,主要用于同时去除污水中的有机物、氮和磷污染物。其核心优势在于“一池三效”,即在一个流程中实现碳、氮、磷的同步降解,成为市政和工业污水处理的主流工艺之一。 三阶段协同:从有机物到氮...
第三节生物脱氮除磷A2O(AAO)(Anaerobic-Anoxic-Oxic)第八章 城市污水的深度处理 2019/2/17 河北科技大学环境科学与工程学院 1 第一节 概述 城市污水经传统的二级处理以后，绝大部分悬浮固体和溶解性、胶溶性的有机物被去除，应达到相关的标准要求。随着不断发展的环境保护和水资源利用的需要，国家相关的新标准...
The objective of this study was to investigate the changes of microbial communities in different treatment units of a full-scale wastewater treatment plant (WWTP) equipped with a serially combined rotating biological contactor (RBC) and anaerobic-anoxic-oxic-oxic (A2/O2) processes. High-throughput ...
A2/O工艺是Anaerobic-Anoxic-Oxic的英文缩写,是厌氧-缺氧-好氧生物脱氮除磷工艺的简称。这种工艺处理效率一般能达到:BOD5和SS为90%～95%,总氮为70%以上,磷为90%左右,一般适用于要求脱氮除磷的大中型城市污水厂。 û收藏 转发 评论 ñ赞 评论 o p 同时转发到我的微博 按热度 按...
The invention discloses an AAO (Anaerobic-Anoxic-Oxic)-biological contact oxidation strengthened denitrification and dephosphorization device and a real-time control method of low C/N sewage treatment. The system is mainly composed of a raw water tank, an AAO reactor, an intermediate sedimentation ...
The performances of anaerobic-anoxic-oxic processes with (A2O-B) and without (A2O-C) beneficial microorganisms were compared to provide valuable insights on how they are affected by changes in the microbial biomass and community composition. Although the A2O-B process showed lower concentrations of ...
