摘要
阐述了影响SBR脱氮除磷的因素（如污泥颗粒化、沉淀时间、进水COD负荷等）和最佳条件。取一定体积的城市污水,测量其进水COD、氨氮、总氮、总磷,并通过向SBR反应器污水中接种城市废水絮凝污泥,设定不同的循环周期,改变每个周期的沉淀时间等改进,培养颗粒化污泥促进其对处理结果的影响。通过实验得出水力停留时间、污泥龄,曝气时间、进水负荷、以及是否投加碳源,即不同碳氮比等因素对SBR处理效果的影响,检测不同周期氮磷的去除率。
Influence factors （such as particles of sludge, sediment time, effluent COD load and so on） for nitrogen and phosphorus removal rate in SBR were introduced as well as the best conditions. A certain volume of urban sewage was used as sample, its COD, ammonia nitrogen, total nitrogen （TN）, total phosphorus （TP） were measured, then treatment of the sewage in the SBR was studied. Effect of hydraulic retention time, sludge age ,influent loading, aeration time and C/N ratio on treatment result was investigated, and removal rates of nitrogen and phosphorus at different stages were determined
