目的为了解济南市居民小区饮用净水卫生状况,为保障饮水安全和强化卫生管理措施提供依据。方法随机调查济南市辖区内部分居民小区自助售水机生产和管理单位的设备维护和管理制度执行情况,并现场采集自助售水机内水样进行检测,对检测结果进行评价。结果饮用净水供应单位在自助售水机的设备维护与管理制度执行方面存在诸多问题;饮用净水检测合格率为71.17%,市政管网水合格率为61.96%(P>0.05)。检测结果的平均值比较分析,饮用净水的pH和菌落总数显著高于管网水(P<0.01),饮用净水的浑浊度、总硬度、溶解性总固体、耗氧量、氯化物、硫酸盐、铁、锰、氟化物、硝酸盐等10项指标显著低于管网水(P<0.01)。结论饮用净水并不显著优于市政管网水,尤其是微生物指标。
Objective To understand the hygienic status of drinking water purification in residential quarters in Ji’nan, to provide basis for ensuring drinking water safety and strengthening health management measures. Methods Randomly investigate the implementation of the equipment maintenance and management system of the self-service water dispenser production and management units in some residential quarters in Jinan City and collect the water samples from the self-service water dispenser on site to evaluate the test results. As a result, drinking water supply units had many problems in the implementation of self-service water dispenser equipment maintenance and management system. The passing rate of drinking water testing was 71.17% and that of municipal pipe network was 61.96% (P> 0.05). The results of the average comparative analysis showed that the pH of drinking water and the total number of colonies was significantly higher than that of water (P <0.01), drinking water turbidity, total hardness, total dissolved solids, oxygen consumption, chloride, Sulfate, iron, manganese, fluoride, nitrate and other 10 indicators were significantly lower than that of water (P <0.01). Conclusion Drinking water is not significantly better than the municipal pipe network water, especially microbial indicators.
