目的分析漳州市区二次供水水质卫生状况,为水质卫生监管提供依据。方法对2015年漳州市CDC抽检的二次供水水质检测结果进行分析,按GB 5749-2006《生活饮用水卫生标准》评价。结果全年共检测水样102份,总合格率20.6%,丰水期、枯水期各51份,合格率分别为13.7%和27.4%;合格率低于90%的项目:消毒剂指标37.2%、微生物指标74.5%、一般化学指标88.2%;主要超标项目:游离余氯37.2%、菌落总数77.4%、总大肠菌群87.2%。不同单位水质合格率:酒店33.3%、学校33.3%、部门单位16.7%、住宅小区54.2%。结论漳州市区二次供水水质合格率偏低,应加强二次供水监管,提高水质卫生质量。
Objective To analyze the secondary water quality and sanitary status of Zhangzhou urban area and provide the basis for water quality health supervision. Methods The secondary water quality of CDC sampled in Zhangzhou in 2015 was analyzed and evaluated according to GB 5749-2006 Standard of Drinking Water Quality. Results A total of 102 water samples were collected during the year, with a total pass rate of 20.6%. During the wet season and the dry season, 51 samples were passed, with pass rates of 13.7% and 27.4% respectively. Items with a pass rate of less than 90% Microbial indicators 74.5%, the general chemical indicators 88.2%; major over-standard items: 37.2% free residual chlorine, the total number of colonies 77.4%, 87.2% of the total coliform bacteria. The qualified rate of water quality of different units: 33.3% of hotels, 33.3% of schools, 16.7% of departmental units and 54.2% of residential quarters. Conclusion The qualified rate of secondary water supply in Zhangzhou urban area is relatively low. Secondary water supply supervision should be strengthened to improve the quality of water quality and hygiene.
