摘要
改良A2/O工艺中预缺氧池有较强的脱氮作用,其脱氮作用占整个系统氮去除率的15.11%。通过对预缺氧池氮元素进行物料平衡,分析和证实改良A2/O预缺氧池中可以发生厌氧氨氧化反应,可以有效减少能耗和降低运行成本,这对我国污水厂的改造,提高出水水质,具有积极意义。
Pre-hypoxia pool of improved A2/O process is good at the nitrogen removal, with nitrogen removal in the prehypoxia pool accounting for 15.11% of nitrogen removal in the whole system. By the material balance of nitrogen in the prehypoxia, anaerobic ammonium oxidation (ANAMMOX) which is confirmed and is possible in improved A2/O process is useful for the reconstruction of wastewater treatment plant, with energy saving and cost effectiveness.
