Objective To explore application value of microbial testing technology in detection of drinking water.Methods The paper chose 50 samples from both wet and dry seasons from March 2020 to May 2022 with different sample testing techniques,including membrane filtration(control group)and multi tube fermentation(observation group).Microbial detection results between two groups were compared.Results There was no significant difference in detection results of mixed bacteria and Escherichia coLI between two different testing methods,(P>0.05).Observation group had better detection effect of heat-resistant Escherichia coli and Escherichia coli than control group(P<0.05).Conclusion Both detection methods have certain detection effect for microorganisms in drinking water,which is helpful for determination of water quality.However,multi tube fermentation method can relatively achieve better effect.
