| 摘 要： | 分别以甲醇(SBR1#)和乙醇(SBR2#)作为碳源,研究了其对单级好氧生物除磷的影响.结果表明,稳定运行条件下,SBR1#磷的平均去除量为6.56mg/L,平均去除率为52.63%.SBR2#中磷的平均去除量为11.22mg/L,去除率为90.34%. SBR1#和SBR2#一个周期运行中好氧吸磷速率分别为1.62mg/(g×h)(以PO43--P计)和5.31mg/(g×h)(以PO43--P计),其中SBR2#出水磷的浓度低于检出限,SBR2#的储能物质总累积量比SBR1#多.相比之下,乙醇是作为除磷碳源效果较好.静置期,由于SBR2#中聚磷菌生物活性较SBR1#高,代谢旺盛,其释磷量高于SBR1#. |

| Abstract: | The research carried out methanol(for SBR1#) and ethanol(for SBR2#) as the sole carbon source,and investigated the effects of them on the efficiencies of biological phosphorus removal in the single-stage oxic process,respectively.The results showed that the average phosphorus removal contents and its efficiencies respectively reached at 6.56 mg/L,52.63% in SBR1# and 11.22mg/L,90.34% in SBR2# during the steady-state operation.For a typical SBR cycle,within aerobic period,the phosphate uptake rates could reac... |
