中文摘要：

在污泥停留时间为15 d、HRT为1.5 h和DO的质量浓度约为2.5 mg.L-1条件下,分别对人工配水和实际生活污水进行了（AO）2SBR法同步脱氮除磷试验,并对处理效果进行了对比。结果表明,人工配水和实际污水的（AO）2SBR工艺好氧和缺氧脱氮除磷过程几乎全部以厌氧阶段合成的胞内聚羟基烷酸为碳源,说明反硝化脱氮除磷确实可实现＂一碳两用＂;人工配水和实际污水的好氧吸磷率分别为67.49%和93.42%、缺氧除氮率分别为58.22%和77.98%,实际污水驯化得到的反硝化聚磷菌和聚磷菌具有更强的反硝化能力和好氧吸磷能力。

英文摘要：

Experiments were carried out in the anaerobic/ aerobic/ anoxic/aerobic manner with a sequencing batch reactor which was fed with synthetic wastewater and municipal wastewater respectively under the condition which was DO≈2.5 mg·L-1,HRT=1.5 h,SRT=15 d,and the treatment effect were compared.It was resulted that most carbon sources of nitrogen and phosphorus removal in the aerobic and anoxic stage were intracellular polyhydroxyalkanoates for synthetic wastewater and municipal wastewater,aerobic phosphors removal ratio for synthetic wastewater and municipal wastewater were 67.49% and 93.42%,and anoxic phosphors removal ratio for synthetic wastewater and municipal wastewater were 58.22% and 77.98%,denitrifying phosphate-accumulating organisms and phosphate-accumulating organisms cultured by municipal wastewater had better capability of acclimatizing to environment,aerobic phosphorus absorbing and anoxic denitrifying.
