| 摘 要： | 前置反硝化生物滤池具有良好的脱氮性能,回流比是影响其脱氮性能的重要影响因素.调节回流比参数,考察回流比分别为100%、200%、300%时的工艺参数条件下,前置反硝化生物滤池对COD、NH3—N、NO3-—N、TN的去除效果.试验表明回流比对反应器中COD、NH3—N、NO3-—N、TN均有一定的影响,对TN的去除影响最大.在一定的范围内(100%~200%),增加回流比有助于提高系统对污染物的去除,但当回流比过大时(300%),系统出水水质下降.确定最佳回流比为200%,该工况下系统出水COD、NH3—N、TN平均质量浓度分别为28.45、2.27、12.45 mg/L.

| Abstract: | The pre-denitrification biological aerated filter （ BAF ） has better performance of nitrogen removal .The reflux ratio parameter is important influence factor of nitrogen removal performance.The removal efficiencies of COD ,NH3-N,NO3-N,and TN at the reflux rati-os of 100%, 200%and 300%were investigated by adjusting reflux ratio parameter .Results showed that the reflux ratio exerted a influence on all removals of COD , NH3-N, NO3 --N, and TN, among which TN was the most sensitive parameter .In a limited range（100%~200%） , the increase of reflux ration improved the removal of contaminants .The effluent of pre-denitrification BAF deteriorated under the extremely high reflux ration （ 300%） .It was determined that a reflux ratio of 200%was the optimum .Under this reflux ration , the con-centrations of COD, NH3-N and TN in the effluent were 28.45,2.27,12.45 mg/L, re-spectively . |
