摘　　要：目的了解厦门市湖里区生活饮用水水质的卫生安全状况,为生活饮用水的卫生监管提供科学依据。方法对湖里区2008～2011年管网末梢水及二次供水监测资料进行分析,分析指标主要包括微生物指标、毒理指标、感官性状和一般化学指标、消化剂指标和水质参考指标。结果监测水样中,管网末梢水的整体合格率为86.30%,二次供水为71.51%,管网末梢水的整体合格率高于二次供水。管网末梢水整体合格率的年度差异有统计学意义,第二年度最低,第三年度最高。生活饮用水合格率在单位类型间的差异有统计学意义,管网末梢水以餐饮业最高,二次供水以纯住宅楼最高。结论湖里区的生活饮用水整体合格率有待进一步提高,应从采用分段加压和加氯技术、更换供水管材质、定期清洗二次供水水池,加强薄弱环节的卫生监管等多方面改善水质。OBJECTIVE To investigate the sanitary situation of the drinking water in Huli district of Xiamen and provide scientific basis for strengthening the supervision and management of drinking water supply.METHODS Samples of the terminal tap water and the secondary water supply were analyzed by statistics from 2008 to 2011.The major analysis indicators included microbial indicators,toxicological indicators,sensory properties and chemical indicators,digestive indicators and water quality reference indicators.RESULTS The total qualification rate was 86.30% for the terminal tap water,and 71.51% for the secondary water supply.The total qualification rate of the terminal tap water was higher than that of the secondary water supply.The total qualification rate of the terminal tap water were significantly different in each year,the second year highest and the third year lowest.The total qualification rate of the drinking water was significantly different in the use of the buildings,the catering industry highest in the terminal tap water and the pure residential buildings highest in the secondary water supply.CONCLUSION The total qualification rate of the drinking water in Huli District should be further improved by using sub-pressure and chlorination technology,replacing the material of the water supply pipe,cleaning secondary water pools regularly and strengthening the monitor to weak links.
