| 摘 要： | 为了研究低溶解氧微膨胀状态下污染物的去除效果，采用SBR反应器，平均DO浓度为0.5～0.9 mg/L，通过好氧/缺氧(O/A)的运行方式，对污染物处理效果进行研究。结果表明：低溶解氧丝状菌污泥微膨胀状态下，SVI可稳定控制在200 mL/g左右,出水SS含量很低，COD去除率在80%以上，氨氮去除率90%以上，除磷效率在90%之上，出水水质良好，同时可以节约曝气量约46.7%。低溶解氧微膨胀状态下，可保证出水处理效果，污泥沉降性能影响小，同时可以节约动力费用。 |

| Abstract: | In order to investigate the pollutant removal effect with low DO and sludge micro-bulking,the sequence batch reactor(SBR) operated in aeration/anoxic(O/A) process with mean DO value 0.5~0.9 mg/L has been studied.The results showed that the effluent water quality was good with low SS value,the SVI could be controlled at 200 mL/g,and the removal rates of COD,ammonia and phosphorus could reach 80%,90% and 90%,respectively.At the same time the aeration flow could be saved to 46.7%.It is concluded that the activ... |
