【摘要】 给水管网中各监测点的水质因子项目繁多,仅仅靠单因子指标不能反映出监测点的水质总体情况,也不利于将水质状况对外发布.为了对给水管网水质进行总体的综合分析,需要进行综合性的科学评价.本文讨论了三种水质指数评价模型:原始水质指数模型、水质综合指数模型、Nemerow水质指数模型,阐述了不同水质指数的原理并给出了具体计算公式.结合实例分别应用三种水质指数模型对管网水质进行评价.实例证明:水质指数模型具有综合概括、简明扼要的特点,使给水管网水质的评价结果更加客观、合理.更多还原

【Abstract】 In order to analyze the water quality synthetically in water supply networks,general scientific evaluation is necessary.Three index number models of water quality including original index number model,index number synthetical model and Nemerow index number model.are discussed.The principles and calculating formula are introduced as well,The water quality of an example in networks is evaluated by the above three models.It proves that the models are general and concise,which makes the valuing results more objective and reasonable.更多还原
