摘　　要：目的了解某污水处理厂空气污染状况。方法从微生物学角度连续二年进行多次的空气气溶胶中微生物检测。结果该厂空气中检出致病菌（金黄色葡萄球菌和肺炎双球菌）及条件致病菌（大肠杆菌和草绿色链球菌等），且大部分菌谱与污水中菌谱相同。厂内各采样点的细菌总数和大肠菌群数明显高于清洁对照点。结论厂内空气已受到生产过程中产生的微生物气溶胶的污染。Objective To assess the air pollution over a sewage treatment plant. Method The microbe in the aerosol has been tested at the microbiology angle in the past two years continously. The microbe in the aerosol continuously at the microbiology angle was tested during the last two years. Results Pathogens such as staph. aureus. Dipococcus pneumonic and opportunitic pathogens such as streptococcus viridans , escherichia coli were detected. The bacterial respectrum in the aerosol was the same as that in the sewage. The total bacterial count and coliform bacteria in the plant were more than that in the control. Conclusion The air in the sewage plant had been polluted by the microbe aerosol during the sewage treatment.
