目的了解泉州市城区生活饮用水水质状况和变化趋势,分析影响因素。方法对2002—2012年泉州市区8家水厂出厂水卫生监测结果分析评价。结果 2002—2012年共检测582份水样,总合格率61.3%。合格率由2002年的59.2%提高到2012年的81.7%,呈逐年升高趋势。5家市政水厂合格率(63.0%),3家自建水厂合格率(54.9%)。春夏季合格率(54.9%)比秋冬季合格率(68.6%)低。影响水质的主要合格率的主要是浑浊度、锰、氨氮、色、铁及微生物指标。结论泉州市区水厂出厂水水质逐年提高,但仍存在安全隐患。要加强水源水保护,改进水厂制水工艺和技术,加强行业监管,进一步提高水质合格率。
Objective To understand the status quo and trend of drinking water quality in urban area of Quanzhou and analyze the influencing factors. Methods Analyzes and evaluates the results of factory water hygienic monitoring of 8 waterworks in Quanzhou from 2002 to 2012. Results A total of 582 water samples were tested during 2002-2012, with a total pass rate of 61.3%. The passing rate increased from 59.2% in 2002 to 81.7% in 2012, showing an increasing trend year by year. 5 municipal waterworks pass rate (63.0%), 3 self-built waterworks pass rate (54.9%). The passing rate in spring and summer (54.9%) is lower than the passing rate in autumn and winter (68.6%). The main qualified rate of water quality is mainly turbidity, manganese, ammonia nitrogen, color, iron and microbial indicators. Conclusion Quanzhou urban waterworks factory water quality increased year by year, but there are still potential safety problems. To strengthen the protection of water sources, improve the water system of water technology and technology, strengthen industry regulation, to further improve the water quality pass rate.
