【摘要】：目的了解宁夏公共场所集中空调通风系统卫生状况,分析其变化规律,为加强监管提供依据。方法通过现场采样和实验室检测方法,对全自治区5个地级市辖区内155套集中空调通风系统进行了卫生学监测。结果对155家集中空调系统进行监测,全部监测指标均合格的有110家,平均合格率为70.97%。连续3年各年度平均合格率依次为72.00%、68.63%和72.22%。集中空调系统管道内表面真菌数超标率较低,平均合格率为98.47%;2011-2013年度各年度平均合格率依次为96.67%、99.33%和99.37%。2013年度从25份空调系统冷却水中检出3份嗜肺军团杆菌,检出率12.00%。结论宁夏公共场所集中空调通风系统总体卫生状况不佳,但真菌污染比较轻,应当加强监督监测力度和卫生管理。
[Abstract]:Objective to understand the sanitary condition of centralized air conditioning and ventilation system in public places in Ningxia, analyze its changing law, and provide the basis for strengthening supervision. The hygienic monitoring of 155 central air conditioning and ventilation systems in 5 prefectural municipal districts of the whole autonomous region was carried out. The average qualified rate was 70.97. The average qualified rate of each year was 72.00% and 72.22% respectively for three consecutive years. The number of fungi on the inner surface of the central air conditioning system was lower than the standard rate. The average qualified rate in 2011-2013 was 96.6767 / 99.33% and 99.37.2013 respectively. Three samples of Legionella pneumophila were detected from 25 samples of cooling water of air conditioning system, and the detectable rate was 12.00. Conclusion the overall hygienic condition of centralized air conditioning and ventilation system in public places in Ningxia is not good. But the fungus pollution is relatively light, should strengthen the surveillance and the hygiene management.
