摘要
目的了解甘肃省降氟改水型水窖水质卫生学状况以及相关的影响因素,为水窖建设提供依据。方法采用分层随机抽样的方法 ,选取适宜的调查点开展问卷调查,并随机采集窖水水样进行分析。结果抽检水样水氟指标全部合格,不合格指标主要是微生物学指标,其次为感官性状指标,其中合格率最低的指标为总大肠菌群(40.00%)和肉眼可见物(40.00%)。结论甘肃省饮水型氟中毒病区修建降水集流型水窖可以达到降氟改水的效果,微生物学指标和感官性状指标有不同程度的超标,应加强宣传教育,科学修建水窖,提高居民的安全饮水意识,加大农村改水力度。
OBJECTIVE To understand the change in Gansu Province to reduce fluoride water-quality cellar hygiene status and related factors, in order to provide a basis for building water cellars. METHODS A stratified random sampling method to select suitable points for the survey questionnaire, and pit water of samples randomly collected for analysis. RESULTS Sampling results of water samples of water fluoride targets all qualified, unqualified indicator is mainly microbiological indicators, followed by the sensory properties of indicators, including indicators of the lowest passing rate of the total coliforms(40.00%),and visible matter(40.00%). CONCLUSION Gansu Province, the construction of drinking water, fluorosis areas set of flow patterns of precipitation can be achieved cellars to reduce fluoride to change the effect of water, microbiology indicators and sensory traits have different degrees of exceeding targets, we should strengthen publicity and education, science and the construction of caverns, and to improve residents awareness of safe drinking water, increase rural waterworks efforts.
