目的了解我国南方3省农村集中式供水水源隐孢子虫与贾第鞭毛虫污染现状。方法采用《生活饮用水标准检验方法微生物指标》(GB/T 5750.12)中Filta-Max Xprss方法对水样进行检测,并调查水源地和水厂的基本情况。结果所调查的水源水隐孢子虫卵囊与贾第鞭毛虫孢囊检出率分别为23.33%和33.33%,部分水源地缺乏防护措施或措施不完善,所调查的农村水厂多采用传统水处理工艺,管理人员对“两虫”来源的相关知识不甚了解。结论调查地区以地表水作为水源,“两虫”检出率较高,提示应该进一步加强水源地防护,完善水厂水处理工艺,加强水厂管理人员对“两虫”相关知识的培训。
Objective To understand the status quo of the contamination of Cryptosporidium and Giardia in rural centralized water sources in three southern provinces in China. Methods The method of Filta-Max Xprss in “Microbiological Index of Standard Test Method for Domestic Drinking Water” (GB / T 5750.12) was used to test the water samples and the basic situation of water sources and water plants was investigated. Results The detection rates of Cryptosporidium oocysts and Giardia cysts were 23.33% and 33.33%, respectively. Some of the water sources were lack of protective measures or measures. The surveyed rural waterworks used traditional water Processing technology, management personnel “two caterpillars ” source of knowledge is not well understood. Conclusion The survey area uses surface water as the water source, and the higher detection rate of “two insects” suggests that water source protection should be further strengthened to improve the water treatment process of waterworks and strengthen the knowledge of water plant managers on “two worms ” Training.
