| 摘 要： | [目的]研究不同有机负荷条件下曝气时间对SBR系统的影响。[方法]通过改变进水有机负荷及曝气时间,了解不同有机负荷运行条件下,曝气时间对SBR系统的影响。[结果]搅拌/曝气时间分别为2.5 h/7.5 h时,COD与TP的去除效果最佳。此时,在低、中有机负荷运行条件下,COD和TP的出水浓度均达到了《城镇污水处理厂污染物排放标准》(GB18918-2002)一级B标准。而高有机负荷运行条件下,COD和TP的出水浓度均未达到《城镇污水处理厂污染物排放标准》(GB18918-2002)一级B标准,但COD和TP的去除效果较高。[结论]不同有机负荷条件下,曝气时间对SBR系统有明显影响。 |

| Abstract: | [Objective] The research aimed to study influence of the aeration time on SBR process at different organic loading conditions.[Method]By changing organic loading of the inlet and aeration time,influence of the aeration time on SBR process was understood at different organic loading conditions.[Result]When stirring / aeration time was 2.5 h /7.5 h,removal effects of the COD and TP were the best.At this time,at low and middle organic loading conditions,COD and TP concentrations in effluent both reached Level-one B criteria specified in Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant（GB18918-2002）.At high organic loading condition,both COD and TP concentrations in effluent did not reach Level-one B criteria specified in Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant（GB18918-2002）.But removal effects of the COD and TP were higher.[Conclusion] At different organic loading conditions,aeration time had obvious influence on SBR process. |
