摘要
采用多管发酵法、滤膜法及快速纸片法3种方法测定饮用水中的总大肠菌群,并从检测原理、步骤、适用范围以及检测结果进行对比分析,讨论了3种方法的优缺点。结果表明,与传统的多管发酵法和滤膜法相比,快速纸片法具有操作简便、检测时间较短、准确度高等优点。
Total coliform bacteria in drinking water determined by three methods namely multi-tube fermentation method,membrane filter method and paper strip method. It also makes comparative study from aspects i.e. test principle and procedure, scope of application and test result, discusses the advantages and disadvantages of the three methods. According to the result, compared with the traditional fermentation method and the membrane filter method, the paper strip method has the advantages such as simple operation, short test time and high accuracy etc.
