摘　　要：利用3 1P—核磁共振谱图证实了生物除磷的机理 ,即除磷菌在厌氧条件下分解胞内的聚磷酸盐并释放出正磷酸盐形式的无机磷酸盐 ,而在好氧或缺氧条件下吸收胞外的无机磷酸盐后转化为聚磷酸盐而贮存于胞内。同时证明了淹没序批式生物膜反应器中磷的去除是由生物完成的。The 31 P-NMR (nuclear magnetic resonance) spectrograms were used to demonstrate the mechanism of biological phosphorus removal. It was verified that the phosphorus removal bacteria decompose intracellular polyphosphate and release inorganic phosphate in the form of orthophosphate under anaerobic conditions; and under aerobic or anoxic conditions, the inorganic phosphate is taken up, with excess amounts stored as polyphosphate in bacterial cells. It was also demonstrated that phosphorus removal in the submerged sequencing batch biofilm process is achieved as a result of biological action.
