摘　　要：在分析单级活性污泥法在除磷脱氮中存在不足的基础上 ,提出了两种双级序批式活性污泥反应器串联运行的除磷脱氮工艺模式。通过合理地控制操作过程 ,采用该工艺可使功能不同的微生物在各自有利的条件下生长 ,提高系统除磷脱氮的效果和稳定性。模式 1工艺适用于处理BOD5 /TP值较高的污水 ;模式 2工艺对进水的BOD5Two process models of two-stage sequencing batch reactor with series operation for biological phosphorus and nitrogen removal are presented based on analysis of the defects of single-stage activated sludge method. Through rational control of operation processes, it is expected to solve the problems encountered in single-stage process, such as carbon source, SRT, nitrate in anaerobic zone, organic compounds resistant nitrification, longer time aeration, and higher power consumption, etc. It will make microbe with different functions to grow in respectively beneficial conditions. Consequently, the effect and stability for the system can be greatly improved. The process of model 1 is suitable for treating wastewater with higher BOD 5/TP, whereas that of model 2 is not sensitive to BOD 5/TP.
