The adverse impact of sewage treatment plants on the environment, resulting from the emission of harmful biological agents to the atmosphere, depends mainly on the size of the facility, the quantity and composition of treated sewage as well as the technologies and equipment used. The aim of the conducted research was to determine the microbiological quality of atmospheric air at Municipal-Industrial Sewage Treatment Plant in Oświęcim, which is one of the largest treatment plants in Lesser Poland. Bioaerosol measurements were made at four points (raw sewage inlet, aeration chamber, purified sewage outlet and 150 m from the treatment plant, at the background point) in the period from January to December 2018. Bioaerosol samples were collected using Microbiological Air Sampler MAS-100 by Merck. The tested atmospheric air was characterized by a qualitatively and quantitatively diverse microflora. The largest source of emission of microorganisms to the atmosphere was the mechanical part of the sewage treatment plant (raw sewage inlet) and the biological reactor. The highest number of mesophilic bacteria was observed near the biological reactor (in the summer), the least at the control point. During the research, the least β-hemolytic bacteria was isolated at the purified sewage outlet—on average 3 CFU m −3 , the highest at the biological reactor 16 CFU m −3 . Most of α-hemolytic bacteria was observed near the raw sewage inlet and was not found at the control point. Actinomycetes also occurred in a small amount (0–40 CFU m −3 ). A high concentration of mildew fungi occurred in summer when the air temperature was highest, the smallest quantities of these microorganisms were found in January and February.

小波兰选定污水处理厂大气空气微生物质量评价
污水处理厂因向大气排放有害生物制剂而对环境造成的不利影响,主要取决于设施的规模、处理后污水的数量和成分以及所使用的技术和设备。进行研究的目的是确定 Oświęcim 的市政工业污水处理厂大气空气的微生物质量,该污水处理厂是小波兰最大的污水处理厂之一。2018 年 1 月至 12 月期间,在四个点(原污水入口、曝气室、净化污水出口和距处理厂 150 m,背景点)进行了生物气溶胶测量。使用微生物空气采样器 MAS 收集生物气溶胶样品-默克 100。测试的大气空气的特征在于定性和定量上多样化的微生物群落。向大气排放微生物的最大来源是污水处理厂的机械部分(原污水入口)和生物反应器。在生物反应器附近(夏季)观察到的嗜温细菌数量最多,在控制点最少。在研究过程中,净化后的污水出口分离出的β-溶血菌最少——平均3 CFU m -3 ,生物反应器最高16 CFU m -3 。大多数α-溶血细菌在原污水入口附近观察到,在控制点没有发现。放线菌也少量出现(0-40 CFU m -3 )。夏季气温最高,霉菌发生浓度高,
