深圳市坪山新区学校及托幼机构饮用水卫生现况分析

Analysis and Countermeasures of Drinking water Hygienic Situation of Shen-zhen Pingshan New District Schools and Kindergartens

目的研究分析深圳市坪山新区学校及托幼机构饮用水卫生现况,并总结饮用水质量改善的具体措施,为深圳市坪山新区学校及托幼机构的安全饮水提供科学的依据。方法结合国家GB/5750-2012年的《生活饮用水标准检验方法》,对深圳市坪山新区学校和一些托幼机构实际的饮用水情况进行检验,并对饮用水卫生监督检查表进行拟订,调查饮用水的卫生状况。结果抽检水样共100份,检验项目和合格水样符合的有60份,占60%。开水检验时合格率为100%,桶装矿泉水检验,合格率为100%,桶装纯净水,检验的合格率为30%。学校中水样抽取60份,其中30份合格,合格率为50%。托教机构,检验的40份水样中,28份合格,合格率为70%。两者之间水样合格率,差异无统计学意义(P>0.05)。50份桶装水样品中,15份合格样品,其中出水口水样不合格占60%,菌群总数检测不合格占80%,电导率不合格占30%。结论深圳市坪山新区学校和托幼机构饮用水卫生中,桶装纯净水的卫生合格率较低,水污染严重,不仅要加强桶装水生产的监管,同时也要加强饮水机的定期清洗。
