摘要:
采用厌氧/缺氧/好氧交替运行的SBR生物除磷系统,对外碳源与聚磷菌胞内聚羟基烷酸(PHA)合成之间的转化关系进行研究,同时还对PHA合成量与聚磷菌除磷能力进行定量分析.结果表明:厌氧外碳源充足时PHA合成速率与外碳源消耗速率均符合一级速率方程.厌氧后期外碳源不足时发生内源呼吸,有少量磷的吸收,但不属于超量吸磷.好氧吸磷速率符合一级速率方程,聚磷菌每消耗1mgPHB可吸磷1.74mg,属于超量吸磷.本系统最大除磷能力可达38.16mgP/gVSS
Abstract:
A/O-SBR(anaerobic/aerobic alternating enhanced biological phosphorus removal system is used to study carbon source and phosphate accumulating organisms(PAO)intracellular energy storage substance transformation, The PHA synthesis and phosphorus removal ability is also andlyzed.PAO could uptake quick degradation organic matters and synthesis polyhydroxyalkanoates(PHA).When the carbon source was sufficient, PHA synthesis rate and external carbon source consumption rate were consistent with a first-order rate equation. When the carbon source was insufficient, occurrence of endogenous respiration and a small amount of phosphorus absorption took place, but it didn’t belong to excess phosphorus uptake. Aerobic phosphorus uptake rate was consistent with a first-order rate equation. When PAO consumed 1mg PHB it could absorb 1.74mg phosphorus. The maximum phosphorus removal capacity could reach 38.16mgP/gVSS.
