细菌测试粪便大肠菌群,大肠杆菌,总大肠菌群饮用水湖泊溪流池塘水池
注明:我的理解大肠菌是总称,大肠杆菌是其中一族,
因为总大肠菌没有其中的大肠杆菌致病性强,这么重要,
所以弄个总数的测试方法,也能体现总体上被动物粪便污染的水平。
举个例子:
这个colif相当于盲流总人数,
前面的e.coli 相当于其中流氓的人数,是其中比较凶狠一族。
In water, coliform bacteria have no taste, smell, or colour. They can only be detected through a laboratory test. The Canadian Drinking Water Quality Guideline for total coliforms is none detectable per 100 mL. The Canadian Drinking Water Quality Guideline for Escherichia coli
这个指标恐怕也不合格,总大肠菌含量,应该不能检出。
所以这里的厂水,不符合生饮。

chlor
余氯
The majority of Canadians do not have chlorine levels over 2mg/L in their tap water. The World Health Organization suggests using no more than 5mg/L. Most people will smell or taste the chlorine at higher concentrations. Many larger water supply systems use chlorine gas to disinfect water.
中文pdf文件如下,也提到不能超过2mg/L,
最终判断,此指标合格。
