摘　　要：采用有效容积为312L的模型对六箱一体式活性污泥反应器的流态特征及其脱氮除磷性能进行了试验研究。结果表明,周期性交替进水方式增强了反应器系统流态的完全混合性,在工艺上表现为通过反向进水完成混合液以及部分污泥回流。反应器具有良好的去除氮磷的性能,对NH3-N、COD、TN、TP的平均去除率分别为89%、75%、74%、90%,出水水质达到GB18918-2002中的一级标准。A pilot-scale integrative six tanks activated sludge reactor （ISTASR） with effective volume of 312 L was used for researches on the water flow pattern and its capacity in biological removal of nitrogen and phosphorus. The incoming way of periodical alternation enhanced full mixture of the reactor system＇s flow pattern, and displayed technologically the reflux of mixed liquid and partial sludge completed through water incoming in reverse direction. The reactor had better performance ofphosphorus and nitrogen removal. The avcrage removal rates ofCOD,NH3-N,TN,TP were 75%,89%,74%, 90% respectively. The effluent quality reached the first grade standard of GB 18918-2002.
