目前,对于各种饮用水、医院污水以及食物等进行细菌学监测与评价时仍以大肠菌群数为主要污染指标。多管发酵法为普遍采用的检测方法。我国目前应用的除15管法外,多为4管法。15管法较费时费工;4管法结果又过于粗略。如能根据实际情况任意设计管组数,或在同样管数下改变管数组
At present, coliform bacteria counts as the main pollution indicator for bacteriological monitoring and evaluation of drinking water, hospital sewage and food. Multi-tube fermentation method is commonly used detection methods. In addition to the 15-pipe method currently applied in our country, most are 4-pipe method. 15 is more time-consuming and labor-intensive; 4 results of the law are too crude. Such as the actual situation according to the arbitrary design of the number of tubes, or in the same number of tubes to change the tube array
