摘　　要：重点介绍A/O除磷工艺和A^2/O除磷脱氮工艺,以及影响除磷脱氮工艺因素和除磷动力学的研究。工艺研究采用了动态与静态实验方法,采用色质联机研究了有毒有机物的降解情况。试验结果表明,A/O、A^2/O工艺的BOD_5去除率近于二级污水处理厂,A^2/O法TP去除率近于三级污水处理厂,且去除难降解有毒有机物的效率高于传统的活性污泥法。动力学公式的修正使之更适于低碳源的情况。八种影响因素的研究为工艺的设计与运行提供了依据。Studies on the process conditions of A/O and AA/O processes, the factors affecting the processes and the kinetics of phosphorus removal are introduced in this paper. The results of research showed that the efficiency of BOD5 removal was near to that of secondary treatment process and the efficiencies of TP and TN removal of AA/O process were near to that of tertiary treatment process. The removal efficiency of toxic-organic compounds difficult to be degrated was far higher than that of the traditional activated sludge process. The researches of factors affecting the process supply a good condition for design and operation of A/O and AA/O processes.The kinetics of phosphorus removal was also researched in this paper. The Siebrity model was revised, and then applicable to the sewage treatment process with lower C/P value.
