水中细菌总数定量检测试验技巧分析

Analysis of Test Techniques for Quantitative Detection of Total Bacteria in Water

水中细菌总数是衡量水体污染程度的重要指标,无论是地表水、地下水还是饮用水,其检测项目都含有微生物指标。微生物检测有定量和定性两种方式,一般多用定量检测,而肠道致病菌则需要采用定性检测。微生物的生长受环境因素影响,其在合适的条件下呈指数型生长,从而影响微生物检测的准确性。

The total number of bacteria in the water is an important indicator to measure the degree of water pollution,whether it is surface water,groundwater or drinking water,its testing items all contain microbial indicators.There are two methods for microbiological detection,quantitative and qualitative,quantitative testing is generally used,while qualitative testing is required for intestinal pathogens.The growth of microorganisms is affected by environmental factors,and they grow exponentially under suitable conditions,which affects the accuracy of microbial detection.
