[目的]综合评价浦东新区自动售水机出水水质,分析自动售水机水质卫生状况,以保障自动售水机饮用水卫生安全。[方法]以上海市浦东新区辖区内自动售水机为对象(共1 100台),随机抽检110台,运用饮用水水质指数(DWQI)法对检测结果进行综合评价分析。[结果]所抽检的110台自动售水机中,“水质较差”的占46.36%;其次是“水质良好”的占36.36%;“水质差”的占16.36%;“水质很差”的占0.90%;无“水质优良”的自动售水机。[结论]运用DWQI法对自动售水机水质进行评价,能够综合反映自动售水机水质优劣,方法操作简单且具有实用性。本次研究显示,目前浦东新区自动售水机水质现况不容乐观,政府及卫生部门应加强监督与管理,督促自动售水机经营单位规范经营。
[Objective] To comprehensively evaluate the effluent quality of automatic water dispenser in Pudong New Area, analyze the sanitary condition of automatic water dispenser, and ensure the hygiene and safety of automatic water dispenser drinking water. [Method] With the automatic water distributor in Pudong New Area of Shanghai as the target (1,100 units in total), 110 units were randomly sampled and the test results were comprehensively evaluated and analyzed by the method of drinking water quality index (DWQI). [Results] Among the 110 water vending machines sampled, “poor water quality” accounted for 46.36%; followed by “good water quality” accounted for 36.36%; “poor water quality” accounted for 16.36%; “Poor water quality ” accounted for 0.90%; no “water quality ” automatic water dispenser. [Conclusion] Using DWQI method to evaluate water quality of automatic water dispenser can comprehensively reflect the water quality of automatic water dispenser. The method is simple and practical. This study shows that the present situation of water quality of automatic water dispenser in Pudong New Area is not optimistic. The government and health departments should strengthen supervision and management and urge the automatic water dispenser business units to regulate their operation.
