摘　　要：以尾水为研究对象,构建了以丝竹为滤料的反硝化滤池,对比研究了曝气充氧、缺氧和补充碳源3种工况条件下脱氮效果和特性。结果表明:缺氧工况下COD、氨氮、TN去除率分别达到4.50%、6.35%、17.46%,补充碳源工况下COD、氨氮、TN去除率分别达到73.54%、20.41%、23.97%(最高达66.04%),补充碳源工况处理效果更优,曝气充氧工况下脱氮效果最差。补充碳源工况下微生物菌群以变形菌门、酸杆菌门、放线菌门和拟杆菌门等为主,其中有大量的能降解丝竹纤维素、转化分解含氮污染物的微生物。The effluent as the research object, a denitrifying filter with filamentous bamboo as the filter material was developed. The efficiency and characteristics of the nitrogenous compounds’ removal were investigated under three working conditions: aeration, hypoxia and carbon source supplement. The results showed that the removal rates of COD, ammonia nitrogen and TN reached 4.50%, 6.35% and 17.46% under the hypoxia condition. The removal rates of COD, ammonia nitrogen and TN reached 73.54%, 20.41% and 23.97% under the carbon source supplement condition.The microflora were mainly Proteobacteria, Acidobacteria, Actinobacteria and Bacteroidetes under the carbon source supplement, which had the degrading bamboo cellulose capable, transforming and decomposing nitrogen-containing pollutants.
