【摘要】 根据A/O脱氮工艺的运行状况和影响因素 ,提出了应用在线传感器连续测定曝气池中DO浓度、氨氮浓度和硝酸氮浓度 ,并据此调节供氧强度、内循环回流量、有机碳源的投加以及硝化区和反硝化区的大小 ,这是保证A/O脱氮工艺良好处理效果的重要控制策略和思想。同时对近年来国外A/O脱氮工艺自动控制的应用及研究进行了简单的回顾。更多还原

【Abstract】 According to operation status and effect factors of A/O nitrogen removal process, in this article, important control strategies and ideas which using on-line sensors continuously measure dissolved oxygen concentration,ammonium concentration and nitrate concentration in aeration basin and based on them to adjust aeration intensity, internal nitrate recycle, substrate dosing and the ratio of nitrification volume and denitrification volume to protect good effluent are introduced.The foreign recent application and research about A/O nitrogen removal process are also simply presented.更多还原
