摘　　要：目的:通过对芜湖市某高校桶装水及饮水机水样进行检测,评估某高校桶装水及饮水机水样的微生物污染情况,为提高高校饮用水卫生质量提供基础资料。方法:采集某高校由当地不同桶装水厂供应的教师办公室、教师公寓和学生宿舍未拆封桶装水和饮水机冷水出水口水样,依据GB 4789.2.3.15-2010分别进行细菌总数、大肠菌群、霉菌和酵母菌检测。结果:桶装水水样细菌总数的合格率(78.00%)高于饮水机水样细菌总数的合格率(50.00%),差异有统计学意义(P<0.05),而在大肠菌群、霉菌和酵母菌的合格率上差异无统计学意义(P>0.05)。桶装饮用水综合指标合格率(72.00%)高于饮水机水合格率(45.45%),差异有统计学意义(P=0.031)。结论:芜湖市某高校桶装水和饮水机存在微生物污染问题。Objective:To detect the microbial contamination status in barreled water and water dispensers sampled from a higher institution based on Wuhu City for evidence to improve the quality of drinking water supplied in college campus.Methods:Water samples were collected from the intact water barrels and the cold outlets of water dispensers stored at teachers′office,teacher′s flat and students′dormitories in a college campus,and detected for the total bacteria count,coliform,mold and yeast level in accordance with GB 4789.2.3.15-2010.Results:The qualified rate of total bacteria was significantly higher in barreled water samples(78.00%)than in water samples from water dispensers(50.00%)(P<0.05),yet there was no significant difference in the qualification rate for coliforms,mold and yeast(P>0.05).The qualified rate by comprehensive index was obviously higher for barreled water(72.00%)than for water samples from water dispenser(45.45%)(P=0.031).Conclusion:Microbial contamination appears in the barreled water and water dispensers stored in a college campus in Wuhu City.
