摘　　要：根据我国中小型城市生活污水处理的需要,改进SBR部分结构,设计出推流式SBR装置,通过试验寻找推流式SBR运行条件,验证装置对有机物降解效率,同时亦验证装置对氮、磷的脱除效果。研究表明推流式SBR工艺由于特殊的运行方式,对NH3-N和TP的去除彻底,NH3-N去除率最高达到92%,TP的去除率最高达到98.76%,TN的去除率73%,COD去除率达90%。The flow-pushing SBR device is designed on the basis of the partial improvement of SBR structure, appealing to the demand of domestic sewage treatment in our country＇s small and medium cities. According to experiments, the condition of operating the flow-pushing SBR is exploited and the efficiency of the organic matter degradation is proved. Meanwhile, the effectiveness of the nitrogen and phosphorus removal is also testified. The results indicate that the flowpushing SBR achieves the objective of the elimination of NH3-N and TP, with the highest removal efficiency of 92% and 98.76% respectively. Additionally, the removal ratio of TN is 73%, COD is 90%. The above progress is attributed to the special operating mode of the modified SBR techniaue.
