Application of Filtration Membrane Method and Multi-Tube Fermentation Method in the Detection of Drinking Water
In order to explore the application of multi-tube fermentation method and filtration membrane method in drinking water detection,90 samples of drinking water during dry season(December to April next year)and 90 samples of drinking water during wet season(May to September)from Shijiazhuang high-tech industrial development zone of Hebei province in 2022 and 2023 are collected,and tested by filtration membrane method and multi-tube fermentation method.The accuracy and usability of the two microbiological test methods in daily life are compared.The results show that the total detection rate of multi-tube fermentation method is significantly higher than that of filter membrane method.The filtration membrane method is superior to the multi-tube fermentation method in simplicity and detection efficiency,while the multi-tube fermentation method is slightly superior in sensitivity.The application of multi-tube fermentation method in daily water quality detection can improve the detection rate of microorganisms in drinking water,and improve the safety of drinking water for residents.
