摘　　要：目的了解本市饮用水隐孢子虫、贾第鞭毛虫污染状况,建立合理的管理机制。方法于2010年-2016年对北京市部分水源、出厂及末梢水的隐孢子虫、贾第鞭毛虫进行检测及结果分析。结果水源水、出厂水及末梢水共222份,均未检出隐孢子虫和贾第鞭毛虫。上述3种水质908份样品理化指标和微生物指标合格率分别为93. 8%和79. 5%。结论 2010年-2016年检测的部分北京市生活饮用水隐孢子虫、贾第鞭毛虫卫生状况良好,但均有不同程度的微生物污染,应进一步加强监督监测。Objective To understand the pollution status of cryptosporidium and giardia so as to establish a reasonable management mechanism. Methods Cryptosporidium and giardia in water samples collected from source water, finished water and terminal tap water in Beijing were detected and analyzed from 2010 to 2016. Results Cryptosporidium and giardia were not detected in all 222 sampling sites including source water, finished water and terminal tap water. The qualified rate of physicochemical indicators and microorganism indicators of 908 samples collected from three kinds of water sources were 93.8% and 79.5% , respectively. Conclusion The sanitary condition of drinking water is generally good in Beijing from 2010 to 2016, and eryptosporidium and giardia were not detected. However, there are different degrees of microbial contamination, and supervision and monitoring should be further strengthened.
