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。
