摘　　要：为了探讨北京农村地区饮用水中病原细菌的污染特征，2008年9月～2009年12月对该地区居民饮用水中的细菌总数、耐热大肠菌群和总大肠菌群3项细菌学指标进行了检测。结果表明：水样中细菌总数、总大肠菌群、耐热大肠菌群的数量均存在超标现象，平均超限值百分率分别为5．67％，80．77％和25．OO％。分散式供水的3项细菌学指标的超标率均高于集中式供水。不同水源类型微生物指标超标率由高到低依次为山泉水、浅井水、深井水。不同取水方式中，微生物指标超标率由高到低依次为手压泵取水、机器取水、缸内储水。由此得出，农村居民饮用水细菌指数均有超标，存在着不同程度的污染，应采取相应措施，使农村饮用水微生物学指标合格。In order to analyse pollution characteristics of pathogenic bacteria in drinking water, 104 water samples were collected from different drinking water samples at Beijing rural areas from September 2008 to December 2009. The results showed that the un-compliance rates of total bacteria, total coliform and fecal coliform were 5.67%, 80.77% and 25.00%, respectively. The quality of central water supply was better than decentralized water supply. The microorganism un-compliance rates in different water source types in decreasing order was mountain spring, shallow water well, deep well. The microorganism un-compliance rates in different water-supply in decreasing order was hand pump well, machine supply, water cellar supply. The qualified rate of drinking water in rural areas was low with different degrees of contamination. More attention must be paid to improve the quality of drinking water in these villages.
