| 摘 要： | 以中试氧化沟系统活性污泥为研究对象,开展了碳源类型、温度、电子受体和COD浓度对释磷、吸磷过程的影响研究.结果表明:25℃时,以生活污水、乙酸钠和葡萄糖为不同碳源,葡萄糖的释磷、吸磷速率最小,分别为5.12 mg·(g·h)-1和6.43 mg·(g·h)-1,生活污水和乙酸钠的释磷、吸磷速率数值相近.在12、16、20和25℃时,以乙酸钠为碳源,释磷、吸磷速率随温度的升高有不同程度的增加;且好氧吸磷速率随外加COD浓度的增大而减小.当以氧、硝酸盐和亚硝酸盐为电子受体时,吸磷速率的大小排序为:氧硝酸盐亚硝酸盐;缺氧吸磷过程的硝酸盐和亚硝酸盐的消耗量与吸磷量之间的化学计量关系(P吸收/N消耗,质量比)分别为0.96和0.65.
