Abstract:

常温条件下(20~25℃),采用序批式反应器(SBR)研究了2种排泥方式在3个不同梯度污泥龄(40、20、10d)下生活污水的除磷亚硝化效果.结果表明:整个过程亚硝化率都在95%以上,随着污泥龄(SRT)的减小,系统除磷能力逐渐提高,氨氮去除容积负荷逐渐降低;在相同SRT条件下,排污泥床表层污泥比排底层污泥能获得更好的除磷效果和更高的氨氮去除容积负荷.在长期运行中发现,采用排污泥床表层污泥的方式,控制污泥龄为20d,总磷去除率为95.92%~97.12%,出水总磷质量浓度为0.1~0.4mg/L,氨氮去除容积负荷为0.12kg/(m3.d),出水亚硝酸盐氮和氨氮的比值约为1:1,可以实现常温生活污水SBR同步除磷亚硝化的稳定运行,为后续的厌氧氨氧化提供了合适的进水.
