摘　　要：通过改变强化生物除磷(EBPR)工艺好氧反应阶段的反应温度实现对微生物能量代谢活性的改变,进而研究微生物能量代谢活性变化对好氧吸磷能力的影响。在微生物经历完全相同的缺氧-厌氧环境下,分别进入反应温度控制为12、20、28℃的好氧反应器,微生物脱氢酶活性、电子传递体系活性以及参与生化反应三磷酸腺苷(ATP)含量的水平均随着反应温度的上升而提高;随着能量代谢活性的增强,微生物好氧吸磷效率、好氧吸磷动力以及好氧阶段聚β羟基丁酸酯利用效率均相应提高;不同水质之间由于挥发性脂肪酸(VFA)含量不同,微生物能量代谢活性对好氧吸磷能力的影响程度不同,微生物能量代谢活性越强,处理水中VFA含量越高,其除磷能力越强。This paper mainly deals with the effect of different microbes＇ activities on phosphorous removal ability with wastewaters containing different volatile fatty acids （VFAs）. The microbes＇ activities were regulated by changing the environment temperatures that they undergo during oxic stage of enhanced biological phosphorus removal process. Atter the same anoxic stage and anaerobic stage, the microbes showed different dehydrogenase activities, electronic transport activities and ATP contents in oxic stages with different water temperature （12℃, 20 ℃ and 28 ℃, respectively）. The activities increased with temperature and the corresponding phosphorus removal ability, motivation and poly-hydroxy-alkanoates use efficiencies also increased. The degree of this increase varied with VFAs contents. Generally, higher microbes＇ activities and higher VFAs contents led to better phosphorus removal.
