课题来源:目前,国家卫生管理部门对人们普遍饮用的桶装水启封后的卫生安全饮用周期尚无统一规定,生产厂家对此也没有在其产品外观上进行明确标示,部分人直接饮用启封时间较久的水后,发生肠道疾病。桶装饮用水确实存在饮水周期的卫生安全问题。我从微生物类污染的角度对此问题进行了实验与探究。研究结果表明:在夏季高温季节,桶装水开始饮用后,10日之内水质是卫生安全
Source of the project: At present, the national health administrative department has no uniform regulations on the safe drinking cycle after the unpacking of bottled water that people generally drink, and the manufacturer does not explicitly mark the appearance of the product, and some people directly drink the unsealing time. After a long period of water, intestinal diseases occur. Bottled drinking water does have health and safety issues in the drinking water cycle. I conducted experiments and explorations on this issue from the perspective of microbial contamination. The results of the study indicate that water quality is safe and safe within 10 days after bottled water begins to drink in summer hot season.
