补充资料：水的微生物污染参数
用微生物检验反映水受人粪或病原体污染的水质参数。一般采用的有大肠菌群和细菌总数。大肠菌群的检出，表明水已受人粪污染,至于细菌总数,则反映受一般细菌污染的程度。大肠菌群不都来自人粪，有的来自土壤或其他来源。因此，又有采用粪性大肠菌群和粪性链球菌群为水质参数的。同大肠菌群的检验方法相比，粪性大肠菌群的培养温度是44.5°C，而不是37°C或35°C。
随着技术的发展和生活水准的提高，已经开始把病毒列入水质参数。人粪中有多种病毒（例如传染性肝炎病毒），而它们抵抗消毒的能力强于大肠菌群，因此危害性大于病原细菌。由于浓度往往很低，试样需先浓缩，然后检验。浓缩和检验需要专用设备，故还未普及。各国对生活用水一般都有明确的水质标准，普通采用细菌总数和大肠菌群作为参数。有些国家也采用粪性大肠菌群或粪性链球菌群为水质参数。还有采用辅助性或补充性的其他微生物参数的。当城市污水回用于城市给水时，病毒应列为参数。对与人体直接接触的娱乐用水（例如游泳池、天然浴场的水），微生物污染参数类似生活用水，但标准要低得多。游泳和淋浴用水还可能传染眼、耳、鼻、喉、皮肤等方面的疾病，但未见规定相应的微生物污染参数。有的国家对某些水产（如蠔）养殖用水制定了微生物标准。
