目的了解西吉县农村饮用水水源类型、取水方式、分类、覆盖人口及其变化,掌握农村饮用水水质卫生状况、影响因素及存在问题,为水质改进提供决策依据。方法分别于枯水期和丰水期对75个农村生活饮用水点进行监测,并对结果进行分析。结果农村生活饮用水总合格率低,为24.0%。主要超标指标是氯化物、硫酸盐、溶解性总固体、总硬度、氟化物、硝酸盐、细菌总数。经统计学分析,丰、枯水期有显著性差异。结论说明西吉县农村苦咸、高氟水分布广,没有消毒措施,达不到《农村饮用水卫生标准》。
Objective To understand the types of drinking water sources, the way of water intake, the classification, population coverage and their changes in rural areas of Xiji County, and to know the hygienic conditions, influencing factors and existing problems of drinking water quality in rural areas so as to provide the basis for decision-making on water quality improvement. Methods 75 rural drinking water points were monitored in dry season and wet season respectively, and the results were analyzed. Results The total qualified rate of rural drinking water was low at 24.0%. Major indicators of over-standard is chloride, sulfate, total dissolved solids, total hardness, fluoride, nitrate, total bacteria. After statistical analysis, Feng, dry season have significant differences. The conclusion shows that the rural areas in Xiji County are bitter and salty, with high fluoride water distribution and no disinfection measures, thus failing to meet the hygiene standards for drinking water in rural areas.
