目的:通过对鄂伦春自治旗农村饮用水水质进行监测,为改善鄂伦春自治旗农村饮用水卫生状况,保证农村饮用水安全,促进农村水改事业的发展提供理论依据。方法:水样的采集、保存及卫生检测按《生活饮用水标准检验方法》(GB/T5750-2006)进行操作,检测结果按《小型集中式供水和分散式供水卫生标准》(GB5749-2006)评价,所检测的18项指标有一项不合格则该水样即评价为不合格。结果:共检测各类水样425份,总合格率为34.35%。各类水质总合格率分别为:自来水出厂水80.00%、自来水末梢水68.75%、机电井水箱水43.18%、机电井末梢水20.45%、手压井水19.46%。合格率低的指标主要是菌落总数、总大肠菌群、耐热大肠菌群以及水中的铁。结论:鄂伦春自治旗农村饮用水卫生状况令人担忧,相关部门应给予高度重视,农村改水工作迫在眉睫,应推行集中式供水。
OBJECTIVE: To monitor the quality of drinking water in rural areas of Oroqen Autonomous Banner in order to provide theoretical basis for improving the health status of rural drinking water in Oroqen Autonomous Banner, ensuring the safety of drinking water in rural areas and promoting the development of rural water reform. Methods: The collection, storage and sanitation testing of water samples were carried out according to the Standard Test Method for Domestic Drinking Water (GB / T5750-2006). The test results were in accordance with “Small Centralized Water Supply and Distributed Water Supply Sanitary Standards” (GB5749-2006) Evaluation, the test of 18 indicators of a failure of the water sample that is evaluated as unqualified. Results: A total of 425 samples of all kinds of water were tested with a total pass rate of 34.35%. The total qualified rate of all kinds of water quality is respectively as follows: 80.00% of tap water, 68.75% of tap water, 43.18% of electromechanical well water, 20.45% of electromechanical shaft peripheral water and 19.46% of hand-pressed well water. Low pass rate indicators are the total number of colonies, total coliform bacteria, heat-resistant coliform bacteria and iron in the water. Conclusion: The health status of rural drinking water in Oroqen Autonomous Banner is worrying. Relevant departments should attach great importance to it. It is imminent to change the water in rural areas and centralized water supply should be promoted.
