目的:分析我市生活饮用水和水源水微生物状况,为水质卫生管理和监督提供依据。方法:选取我站近年受检的水源水296份,生活饮用水306份,进行不同年度及不同季度的生活饮用水及水源水的菌落总数、耐热大肠菌群、总大肠菌群三项检测。结果:306例生活饮用水水质总合格率69.6%,按季度比较,二季度明显低于其他三季度。296份水源水总合格率为40.8%,各季度间合格率差异不大。结论:丰水期生活饮用水合格率较低,存在水源性疾病爆发的风险,应当加强对生活饮用水和水源水的监督和控制。
Objective: To analyze the status of living and drinking water microorganisms in our city and provide basis for the management and supervision of water quality. Methods: Selected 296 water sources and 306 drinking water in our station in recent years. The total number of colonies, heat-resistant coliforms and total coliform bacteria in drinking water and drinking water in different years and different seasons were selected . Results: 306 cases of drinking water quality of the total pass rate of 69.6%, by quarter compared to the second quarter was significantly lower than the other third quarter. The total qualification rate of 296 water sources was 40.8%, with little difference between the quarters. Conclusion: The low pass rate of drinking water during the wet season risks the outbreak of water-borne diseases and the supervision and control of domestic drinking water and source water should be strengthened.
