| Abstract: | 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. |
