【摘要】 在SBR污水处理工艺中,水温会影响活性污泥微生物的酶促反应、微生物细胞的增殖和内源代谢过程、氧的总转移系数、水的饱和溶解氧浓度、污泥膨胀与水的粘滞性,使以活性污泥为主体的SBR污水处理系统不稳定并降低处理效率。因此,研究低水温条件下SBR污水处理工艺特性对于提高该工艺在低水温下的工艺稳定性和处理效率具有重要意义。更多还原

【Abstract】 By SBR treatment,the enzyme-urging reaction of microbe,multiplication and endogenesis metabolization of microbe cell,the total oxygen-transfer coefficient,the concentration of saturated dissolving oxygen in sewage,the activated-sludge swelling and viscidity of sewage and the bio-chemical reaction of the activated-sludge,were affected by the temperature of water.As a result,the sewage treatment by SBR with activated-sludge as focus would be unstable and the efficiency weakened.Thus it is important to study the technique of sewage treatment by SBR under low-temperature condition.更多还原
