上海市生活饮用水水质指数研究

[目的]探索建立适合上海实际的生活饮用水水质指数,为生活饮用水信息化建设提供方法。[方法]对比不同水质指数的计算式和参数,作适当修改,并对上海市生活饮用水水质检测数据进行水质指数计算,观察和分析各水质指数的合理性。[结果]利用5种计算公式分别对上海市水质监测结果进行指数计算,显示经修正的含＂惩罚项＂的指数计算方法,所得指数能反映水质实际情况。利用五色等级法,对不同公式所得指数以色彩表示,同样验证了上述结果。[结论]提出以袁志彬法为基础,根据新版《生活饮用水卫生标准》修正的含＂惩罚项＂的指数计算方法,既考虑了每个指标对指数的贡献,又通过增加＂惩罚项＂反映超标项目对生活饮用水水质的影响,比较符合上海水质的实际情况。借鉴五色等级分类法,还能使指数更简便易懂。

A Study of Drinking Water Quality Index in Shanghai

[Objective] To establish a scientific and objective index of drinking water quality and to make it in accord with the actual situation in Shanghai. It may lay a foundation for the information construction of drinking water.[Methods] After the properties of drinking water quality in Shanghai were taken into consideration,proper water quality indices were chosen and then calculated by using water quality testing data in Shanghai into a theory based on the comparison and adjustment of several different calcula...
