2、生活污水12,*2梁锐振,赵二杰,周宾1.上海昊沧系统控制技术有限公司,上海2011032.兰州理工大学石油化工学院,兰州730050收稿日期:20070427修回日期:20070727录用日期:20080331摘要:针对国内现行工艺氮磷去除不能兼顾的现实,采用活性污泥、生物膜组合系统(活性污泥、生物膜培养采用原水配水待处理废水逐级诱导培养获得单池相对纯净的生物相,避免了硝化菌与聚磷菌的泥龄矛盾,利用反硝化聚磷!一碳两用∀缓解了碳源竞争问题),并采用独特的聚磷污泥回流方式使全部聚磷菌污泥经历释磷、聚磷循环,克服了水体中氮磷去除不能兼顾的问题.运行结果表明,该工
3、艺对校园生活污水有良好的处理效果,当进水的COD、NH+N、TN、PO3-P的平均浓度为349.84mg#L-1、32.28mg#L-1、35.76mg#L-1、6.45mg#L-1时,出水平Cr44均浓度为14.77mg#L-1、1.46mg#L-1、5.48mg#L-1、0.63mg#L-1,平均去除率分别为957%、95.12%、84.45%、92.01%.长期的运行表明此工艺对氮磷有稳定的去除效果,出水水质满足国家∃城镇污水处理厂污染物排放标准%(GB189182002一级B标准)要求.关键词:反硝化除磷;硝化;逐级诱导;生物膜;活性污泥文章编号:02532468(
