目的:分析农村生活饮用水与城镇生活饮用水微生物检验结果,以便及时发现水污染问题。方法:于2013年~2015年期间,采集当地的农村生活饮用水、城镇生活饮用水等样品共526份,在采样后4小时以内送达实验室,进行微生物检测,观察其水微生物合格率。结果:当地的城镇生活饮用水水样各年度的合格率差异并不大(P>0.05),合格率达到100%;农村饮用水中,集中式供水和分散式供水合格率均低于城市集中供水合格率,但呈现逐年上升的趋势,2015年的菌落总数可达到71.3%,总大肠菌群和耐热大肠菌群则分别达到74.8%和80.2%;各水样本菌落总数合格率均显著低于总大肠杆菌和耐热大肠菌群,差异有统计学意义(P<0.05)。结论:通过对农村生活饮用水与城镇生活饮用水微生物的检测,可明确水质状况,进而采取生活饮用水卫生监督与处理。
Objective: To analyze the results of microbiological tests on drinking water in rural areas and drinking water in urban areas in order to find out the problems of water pollution in time. Methods: From 2013 to 2015, a total of 526 samples of rural drinking water and urban drinking water were collected and sent to laboratories within 4 hours after sampling. Microbiological tests were conducted to observe the qualified rate of water microbes. Results: The percentages of qualified drinking water samples in urban areas were not significantly different (P> 0.05), and the pass rate was 100%. The qualified rate of centralized water supply and decentralized water supply in rural drinking water was lower than that in urban areas The qualified rate of water supply showed a trend of increasing year by year. The total number of colonies reached 71.3% in 2015, and the total coliforms and heat-resistant coliforms reached 74.8% and 80.2% respectively. The passing rates of total colony in each water sample were significantly lower The total Escherichia coli and heat-resistant coliform bacteria, the difference was statistically significant (P <0.05). Conclusion: Through the detection of drinking water in rural areas and urban drinking water microbes, we can clarify the water quality, and then take the health supervision and treatment of drinking water.
