摘　　要：采用SBR反应器处理城市污水处理厂的污泥水,探讨在30℃、25℃和20℃条件下的脱氮性能。结果表明,在不同温度条件下,SBR系统对污泥水中NH4+-N、TKN有很好的处理效果,二者的平均去除率分别为99.3%和97.4%,可大幅度降低其中的NH4+-N负荷,保证硝化的正常进行。但系统的反硝化效率有待提高,TN的平均去除率仅为24.3%。The reject water from WWTP was treated in SBR reactor, the effect of nitrogen removal at 30℃,25℃ and 20℃ were investigated respectively. The results showed that SBR process had a perfect nitrification effect on dealing with the reject water at different temperatures, during the experiment, the average removal rates of NH4^＋-N and TKN were 99.3% and 97.4% respectively, which could significantly reduce nitrogen load and make sure the effect of nitrogen removal.But there was a worse detrification performance with the reject water, the average removal rate of TN was only 24.3%,and the efficiency of denitrification should be improved.
