中文摘要：

采用序批式生物膜反应器（SBBR）处理广州地区的城市污水，当温度为21～35℃时均能实现亚硝酸型同步硝化反硝化。随着温度的上升，氨氧化速率及对TN的去除速率均加快，31℃时达到最大值，其中氨氧化速率为4．71mgNH4＋-N／（L．h），对TN的去除率为84．8％；但当温度升高到35℃时去除速率会略有下降，且所需反应时间延长。在21-35℃的范围内，温度对反硝化菌的影响要小于对亚硝酸茵的，随着温度的升高，SBBR的同步反硝化效果相对得到了加强。利用DO、pH和ORP的变化规律判定反应结束时刻，可以实现对亚硝酸型同步硝化反硝化的过程控制。

英文摘要：

The sequencing batch biofilm reactor （SBBR） was employed to treat municipal sewage in the Guangzhou area. Simultaneous nitrification and denitrification （SND） via nitrite can be achieved when the average temperature ranges from 21 ℃ to 35 ℃. When the temperature is increased, the TN removal rate and ammonia oxidation rate are also accelerated. This trend continues until temperature reaches 31 ℃at which the ammonia oxidation rate is 4.71 mgNH4＋ -N/（ L · h）, and the TN removal rate is 84.8%. When the temperature rises to 35 ℃, the removal rate is slightly decreased, and the reaction time is prolonged. Moreover, in the range from 21℃ to 35 %, the effect of temperature on denitrification bacteria is less than the effect on nitrite bacteria. Also, the increase of temperature causes the strengthening of simultaneous denitrification. The DO, pH and ORP can realize the process control trite. judgment of reaction end time by using change of simultaneous nitrification and denitrification rule of via nitrite.
