摘　　要：本文结合工程实践,从设计的角度分析了可生化降解有机物、溶解氧、泥龄、流程选择等因素对 A^2/O 工艺除磷脱氮效果的影响,提出了采用回流污泥分流、改进提升、搅拌设备等措施来提高除磷脱氮效果.The effects of biodegradable organic compounds and dissolved oxygen contents, activated sludge age and treatment process on the N and P removal of A2/O technology are analysed from the view of design with engineering practice. The measurements to improve the efficiency of denitrification and deposphoration are developed including diversion of returned sludge and upgrading of sludge lifting and mixing equipment.
