污泥颗粒化快速启动厌氧氨氧化反应器的探讨

Methods for rapid start-up of the anaerobic ammonium oxidation process

厌氧氨氧化工艺处理成本低,被认为是有应用前景的废水脱氮技术。但是,厌氧氨氧化菌生长缓慢,厌氧氨氧化反应器启动困难。探讨了几种快速启动厌氧氨氧化反应器的方法,包括投加颗粒污泥、惰性载体、絮凝剂及多价阳离子等,并对其作用机理进行了分析。

The anaerobic ammonium oxidation process （ANAMMOX） is an attractive treatment option for removing ammonia from concentrate wastewater. However, the ANAMMOX reactor start-up is very slow and difficult.The paper presents a detailed review of several rapid start-up methods： supplementation of granular sludge, inert carrier, flocculant and multi-valence cations.
