摘　　要：在建立全程自养脱氮反应器的基础上,以活性污泥为对照,分析了脱氮反应器内真菌、细菌和放线菌的数量、种类(类群)、种(株系)数和优势种(株系或类群),及硝化菌和亚硝化菌的数量变化。研究结果表明,与活性污泥相比,全程自养脱氮反应器内微生物数量、种类和区系组成发生很大变化。自养脱氮反应器内亚硝化菌数量显著增加,说明亚硝化菌的积累是全程自养脱氮系统的一个显著特点。The microbial flora of fungi, bacterial and actinomycetes in tull autotrophic ammonium removal reactor and activated sludge was analyzed, and the amount of nitrite-oxidizing bacteria and ammonia-oxidizing bacteria was also compared. The result showed that the population, species, species number and dominates of microorganisms in full autotrophic ammonium removal reactor were different from that in activated sludge. In full autotrophic ammonium removal reactor, the amount of ammonia-oxidizing bacteria was increased remarkably which indicated that the accumulation of ammonia-uxidizing bacteria was a remarkable feature of full autotrophic ammonium removal system.
