摘　　要：目的应用滤膜法、多管发酵法检验生活饮用水的微生物情况。方法选取新乡市疾病预防控制中心2021年1月至2023年12月收集的100份生活饮用水样,所有样本均进行多管发酵法与滤膜法检验,同时依据检验方案的差异将结果分为研究组(多管发酵法)、对照组(滤膜法),分析其合格率与生活饮用水微生物检出情况。结果研究组检验合格率显著高于对照组,差异有统计学意义(P<0.05);在枯/丰水期生活饮用水微生物的检出情况方面,两组总大肠菌群、杂菌情况基本一致,差异无统计学意义(P>0.05);但在耐热大肠菌、大肠埃希菌群方面,研究组检验显著优于对照组,差异有统计学意义(P<0.05)。结论应用多管发酵法检验生活饮用水的微生物情况在大肠埃希菌、耐热大肠菌群检验及合格率方面均优于滤膜法,具有临床应用意义。Objective To assess the microbial quality of drinking water using the membrane filtration method and the multiple tubes fermentation method.Methods A total of 100 drinking water samples collected by the Xinxiang Center for Disease Control and Prevention from January 2021 to December 2023 were selected for the study.All samples were tested using both the multiple tubes fermentation method and the membrane filtration method.Based on the differences in testing protocols,the results were divided into the study group(multiple tubes fermentation method)and the control group(membrane filtration method),and the detection rates and microbial results in drinking water were analyzed.Results The pass rate for inspections in the study group was significantly higher than that in the control group,with a statistically significant difference(P<0.05).In terms of microbial detection in drinking water during wet and dry seasons,the total coliforms and mixed bacteria detection rates were generally consistent between the two groups with no statistically significant differences(P>0.05).However,the detection rates for thermotolerant coliforms and Escherichia coli were significantly better in the study group compared to the control group,with statistically significant differences(P<0.05).Conclusion The multiple tubes fermentation method demonstrates superior efficacy in detecting Escherichia coli,thermotolerant coliforms,and overall pass rates compared to the membrane filtration method,highlighting its clinical application value in testing the microbial quality of drinking water.
