针对污水处理厂普遍面临的进水碳源不足及冬季低温时出水氮磷不能稳定达标的问题,研究了温度(21、15和10℃)和外加碳源(乙酸)对活性污泥缺氧条件下反硝化及释磷过程的影响。结果表明,在缺氧条件下投加乙酸,释磷与反硝化反应可同时进行,且乙酸投量的增加仅延长快速碳源反硝化阶段及缺氧释磷阶段的反应时间;温度降低为15℃和10℃时,快速碳源反硝化阶段反硝化速率及缺氧释磷速率较21℃分别降低了约29.2%、42.2%和26.1%、32.3%。当硝态氮目标去除量与磷酸盐目标释放量之比超过5时,乙酸的最优投量以满足反硝化要求为准,计算得出21、15和10℃时常州某城镇污水处理厂乙酸最优投加量计算值约为30、39和46 mg/L。
