| 摘 要： | 对单级膜生物反应器（MBR）处理生活污水进行了研究，考察了在四种工况下反应器对COD和氮的去除效果及其影响因素。试验结果表明：反应器对COD具有很好的去除效果，去除率在93％以上；对于氮的去除，反硝化是该工艺的关键控制步骤，通过改变运行工况和增加污泥浓度，使NH^＋4-N的去除率达90％以上，TN的去除率达83％以上。

| Abstract: | Experimental research on treating domestic wastewater with single stage intermittent aeration membrance bioreactor (MBR) was conducted. The removal of COD and nitrogen and influence factors in four operating modes were presented. The result showed that the MBR system exhibits good effect on COD removal, the average removal rate of COD was 93%. Denitrification was the determinative step for nitrogen removal in this system, the removal of nitrogen is increased by changing the operating modes and maintaining high MLSS concentration, NH4-N removal rate excess 90%, TN removal rate excess 83%, have been obtained. |
