摘　　要：探讨了序批式生物膜法反硝化除磷特性及其机理.采用31P-NMR谱图,说明序批式生物膜在缺氧条件下与在好氧条件下相同,无机磷酸盐被转化成聚磷酸盐而贮存,证实了反硝化除磷的机理;在缺氧段反硝化吸磷速率较好氧吸磷速率明显降低,约为好氧吸磷速率的1/6;优势菌依顺序为假单胞菌属、气单胞菌属、芽孢杆菌属、微球菌属.The characteristics and mechanism of phosphorus removal by denitrification with sequencing batch biofilm technique were investigated. The 31P-NMR spectrograms were adopted to explain that it was same under anoxic and aerobic conditions of sequencing batch biofilm, the inorganic phosphate was converted to polyphosphate and stored and confirmed its mechanism. In the anoxic phase, the phosphorus uptake rate was obviously lowered to about 1/6 of that in aerobic phase; and the order of the dominant bacterial species was Pseudomonas, Aeromonas, Bacillus, Micrococcus.
