以新型缺氧序批式反应器和潮汐流生物滤池串联（ASBR-TFBF）组合工艺对不同回流比下的脱氮效能进行研究。ASBR-TFBF组合工艺在整个运行过程中完全未进行曝气，在反应器80 d的运行过程中改变TFBF出水回流液进入ASBR反应器中的比例，并对ASBR及TFBF反应器在各回流比下周期内污染物变化规律进行了研究。结果表明，回流比为50%、100%、200%、300%下，NH4+-N 和 TN 去除率分别为54.37%±1.74%、73.61%±2.96%、83.72%±2.23%、84.06%±1.57%和35.76%±2.89%、50.74%±2.56%、61.55%±3.04%、59.49%±2.33%，COD去除率一直维持在85%左右。

The effects of reflux ratio on the nitrogen removing efficiency of a novel combined process,ASBR-TFBF, under different reflux ratio conditions have been studied. No aeration has been implemented during the whole opera-tion course of the combined process. The proportion of TFBF effluent reflux liquid flowing into ASBR reactor varies in an 80 days running process of the reactor. The pollutant changing rule during the period when ASBR and TFBF reactors are under different reflux ratio conditions has been studied. The results show that when reflux ratios are 50%,100%,200%and 300%,the removing rates of NH4+-N and TN are 54.37%±1.74%,73.61%±2.96%,83.72%± 2.23%,84.06%±1.57%and 35.76%±2.89%,50.74%±2.56%,61.55%±3.04% and 59.49%±2.33%,respectively, and COD removing rate always remains on about 85%.
