摘要
目的了解南平市城乡集中式供水水质卫生状况,为居民安全饮水提供科学依据。方法按照国家卫生标准进行水样采集、检测和评价,对2009—2013年城乡集中式生活饮用水水质检测结果进行统计分析。结果 2009—2013年城乡各类水质平均合格率分别为:城市出厂水79.78%、城市管网末梢水65.82%、农村出厂水32.70%、农村管网末梢水28.47%;城市集中式供水水质明显优于农村集中式供水水质;细菌学和消毒指标是影响饮用水水质合格率低的主要因素。结论南平市城乡集中式供水水质卫生质量有待提高,尤其应加强对农村地区饮用水卫生的监管。
Objectives To master the quality of urban and rural centralized water supplies in Nanping city, and to provide scientific evidence for drinking water security. Methods Water samples from urban and rural centralized water supplies in Nanping were collected, detected and evaluated according to the national standard and the data in 2009-2013 were analyzed. Results The average pass rate of finished water from urban water factories was 79.78% and that from rural water factories was 32.70%. The average pass rate of peripheral water from urban pipe networks was 65.82%, and that from rural pipe networks was 28.47%. The quality of centralized water supplies in urban areas was significantly better than that in rural areas. Bacteriological and sterilization indicators were the major factors impacting the lower quality of drinking water in Nanping. Conclusions The quality of water from urban and rural centralized water supplies in Nanping should be improved; the monitoring and management of rural water supplies should be strengthened especially.
