为寻找合适的饮用水中肠道病毒和寄生虫污染的指示物,作者选择了蒙特利尔的3家水处理工厂采集水样并作病原学(人类肠道病毒、兰氏贾弟鞭毛虫包囊及隐孢子虫卵囊)及可能的指示物(大肠杆菌胞壁噬菌体及雄性噬菌体、产气荚膜杆菌)的分析测定。采集的未处理水样和沉淀后澄清水样每份为100L,过滤后水样和出水水样每份为1000～2 000L。检测结果发现,3家厂所用的河水中以上微生物均能检出,其中唯一与人肠道
To find suitable indicators of enterovirus and parasite contamination in drinking water, the authors selected three water treatment plants in Montreal to collect water samples for etiology (human enterovirus, Giardia cyst and Cryptosporidium oocysts) and possible indicators (Escherichia coli phage and phage, Clostridium perfringens) analysis and determination. The collected untreated water samples and sediment after the clarified water samples each 100L, filtered water samples and water samples for each 1000 ~ 2 000L. Test results showed that the three plants in the river can be detected in more than microorganisms, of which the only and human intestinal
