摘要:
目的 研究出厂水水质综合评价指数(finished drinking water quality index,FDWQI)能否综合反映上海市生活饮用水出厂水的实际情况。 方法 运用FDWQI对上海市13家市级水厂的出厂水水质卫生情况进行评价。 结果 以长江水为水源的水厂全年FDWQI平均值为20.19,每月的评价结果"优"、"良"各半,以黄浦江上游水为源水的水厂全年FDWQI平均值为24.25,每月的评价结果以"良"为主。FDWQI在春季波动较小,冬季变化差异大。 结论 FDWQI的结果与本市水质情况基本吻合,但其科学性、客观性还有待在今后实际应用中进一步验证。 Abstract:Objective To investigate if the finished drinking water quality index (FDWQI) can comprehensively reflect the actual situation of finished water quality in Shanghai. Methods FDWQI was used to evaluate finished drinking water quality of 13 municipal waterworks in Shanghai. Results The average annual FDWQI of the waterworks, of which the water source is the Yangtze River, was 20.19, and the "excellent" and "good" monthly evaluation results were half-and-half. The average annual FDWQI of which the water source is upper stream of the Huangpu River was 24.25, and the monthly evaluation results were mainly "good". FDWQI showed minor fluctuation in summer and major fluctuation in winter. Conclusion FDWQI results are consistent with the water quality in Shanghai. However, the scientificity and objectivity of FDWQI need to be validated in the future application.
