摘　　要：针对污水处理过程中所产生的恶臭气体,对不同处理单元的臭气变化规律、生物除臭系统除臭效果及微生物菌群变化进行了研究,并以恶臭气体在构筑物间的含量、生物除臭反应器内填料和喷淋液上的微生物菌群作为研究对象进行分析。研究发现,硫化氢气体在曝气沉砂池含量最高,经处理后浓度低于1.5 mg/m^(3);氨气在进水区含量较高,经处理后远低于排放标准要求;臭气浓度在曝气沉砂池含量高,经处理后臭气浓度最高为101,去除效果良好。生物除臭系统经运行后微生物菌数有所提升,且固体海绵填料承载微生物菌群的能力比炭质填料更为优异。In view of the malodorous gas generated in the sewage treatment process,the variation of the odor in different treatment units,the deodorization effect of biological deodorization system and the change of microbial community were studied.Besides,the components of the malodorous gas and the microbial community on the filler of the biological deodorization reactor and the spray liquid was analyzed as the research object.The study found that the content of hydrogen sulfide gas in the aerated grit chamber was the highest,and the concentration after treatment was lower than 1.5 mg/m^(3).The content of ammonia gas in the intake area was relatively high,and the concentration of ammonia gas was far below the emission standard requirements after treatment.The odor gas content of the aeration grit tank was high,the maximum odor concentration after treatment was 101 with a great removal effect.After the operation of the biological deodorization system,the number of microorganisms had increased,and the capacity of the solid sponge filler to carry the microorganisms was better than that of the carbon filler.
