| 摘 要： | 采用序批式活性污泥法处理人工配制的城市生活污水，通过控制泥龄成功地实现了亚硝酸盐型同步硝化反硝化，曝气过程中NO2^-N／NOx^-N值始终保持在84．48％以上，曝气结束时大约有80．39％的氨氮通过同步硝化反硝化途径被去除。在适宜的曝气量下，利用排泥的方法控制反应器内适宜的泥龄，可以实现稳定的亚硝酸盐型同步硝化反硝化。

| Abstract: | Nitrogen removal from synthetic municipal domestic wastewater was studied using the sequencing batch reactor(SBR) activated sludge process.Simultaneous nitrification and denitrification via nitrite was successfully realized through controlling sludge age.Experimental results show that for optimal sludge age,the ratio of NO-2-N to NO-x-N remains above 84.48% throughout the aeration phase,and 80.39% of ammonia is removed by simultaneous nitrification and denitrification during the end of the aeration phase.Under the feasible DO concentration,maintaining optimal sludge age by draining the mixture of activated sludge and wastewater at normal temperature can result in a stable simultaneous nitrification and denitrification via nitrite. |
