补充资料:细菌总数
      水质参数之一,单位体积水中的细菌总量。其检验方法是:在玻璃平皿内,接种一毫升水样或稀释水样于加热液化的营养琼脂培养基中,冷却凝固后在37°C培养24小时,培养基上的菌落数或乘以水样的稀释倍数即为细菌总数。有的国家把培养温度定为35°C或其他温度,也有把培养时间定为48小时的。
  
  水中通常存在的细菌大致可分为三类:①天然水中存在的细菌。普通的是荧光假单孢杆菌、绿脓杆菌,一般认为这类细菌对健康人体是非致病的。②土壤细菌。当洪水时期或大雨后地表水中较多。它们在水中生存的时间不长,在水处理过程中容易被去除。腐蚀水管的铁细菌和硫细菌也属此类。③肠道细菌。它们生存在温血动物的肠道中,故粪便中大量存在。水体中发现这类细菌,可以认为已受到粪便的污染。致病性肠道细菌有沙门氏杆菌(伤寒和副伤寒菌)、志贺氏菌(痢疾菌)和霍乱弧菌等。
  
  1976年中国颁布的生活饮用水水质标准规定每毫升水的细菌总数不得超过100个。
