摘　　要：目的了解青岛市托幼机构、中小学饮用水卫生状况及影响因素。方法对全市523所中小学托幼机构饮水方式、饮用水卫生状况开展调查,并采集饮用水样品分析。结果青岛市中小学、托幼机构采用直饮水的占47%,采用以热水为饮水方式的占37%,采用桶装水的占12%,采用混合饮水方式的占4%。抽检的546份水样的水质总合格率为43.77%,523所中小学、托幼机构受检单位合格率为43.40%。结论微生物指标是影响直饮水水质的主要因素,主要不合格指标为菌落总数、大肠菌群、硝酸盐氮。加强中小学、托幼机构饮用水卫生管理及消毒处理是提高直饮水水质合格率的关键。当地饮用水水源水质状况是影响硝酸盐氮的主要因素。Objectives To investigate the hygienic status and influencing factors of drinking water in middle and primary schools and kindergartens in Qingdao city. Methods The patterns and hygienic status of drinking water were investigated in 523 middle and primary schools and kindergartens; the water samples of direct drinking water （ directly from the outlets of drinking water ducts） , boiled drinking water and barreled drinking water were collected and analyzed. Results Direct drinking water pattern was used in 47% of investigated middle and primary schools and kindergartens. Boiled water pattern, barreled drinking water pattern and mixed drinking water pattern were used in 37% , 12% and 4% of schools and kindergartens respectively. The total qualified rate of drinking water supply was in 43.77% of 546 valid samples, and the qualified rate of drinking water supply of 523 investigated schools and kindergartens was 43.40%. Conclusions The main factors influencing the quality of direct drinking water were microbial indexes （including total bacterial count, coliform bacteria） and nitrate nitrogen. Strengthening health management and disinfection are the key points to improve the qualified rate of direct drinking water in middle schools, primary schools and kindergartens. The main factor influencing nitrate nitrogen is the quality of local drinking water sources.
