EM应用于间歇反应器处理城镇污水的高效节能问题

Research on High Efficiency and Low Energy Cost of Adding EM to Sequencing Batch Reactor (SBR) on the Pollutant Removal in the Municipal Sewage

以城镇生活污水为研究对象 ,探讨了在间歇反应器SBR(SequencingBatchReactor)中接种不同比例的EM菌液对污水中COD、各种形态氮及TP降解速率的影响。研究表明 :EM投加比例为 0 .1 10 0 0～ 1 10 0 0时 ,可大大提高上述指标的降解速率 ,缩短SBR工艺的曝气时间和运行周期 ,并使SBR反应器具有较强的抗冲击负荷能力。将EM应用于SBR反应器是高效低耗处理中小城镇生活污水的一种有效技术。

This paper discusses the effect of the degradation speed and removal rate of COD, nitrogen and total phosphorus in domestic sewage by adding Effective Microorganisms (EM) to the Sequencing Batch Reactor (SBR). The results show that EM addition between 0.1/1000 and 1/1 000 can increase removal rate of COD, nitrogen and total phosphorus and reduce the aeration and the reaction time of SBR significantly. The results also show that SBR can fit high pollutant concentration of the domestic sewage efficiently. Thus, Combining SBR with EM is an effective and energy_saving method for the removal of nitrogen, COD and total phosphorus from Municipal Sewage.
