摘 要:[目的]应用改良综合指数法对管道直饮水水质进行评价。[方法]选取细菌、致癌、一般毒理、有机污染、感官性状和一般化学等共34项指标建立管道直饮水综合评价指标体系,根据卫生学意义的不同将指标分成5大类,在此基础上,选用内梅罗法、最差因子判别法和加权平均法,对2008年12月上海市长宁区内的10个居民小区直饮水水质进行综合评价。[结果]直饮水水质综合指数值介于0.34~1.26间,明显低于市政供水。影响直饮水水质的污染因子主要是pH、浑浊度和耗氧量等。[结论]长宁区直饮水水质优于市政供水,但需要特别注意个别指标的污染。[Objective] To apply an improved integrated index method to evaluate the quality of piped drinking water.[Methods] Altogether 34 indicators of water quality including microbial,carcinogenic,general toxic,organic pollution,sensory and general chemical indices were selected into a comprehensive assessment system of drinking water.The candidate indices were classified into five categories according to various hygienic significances.The comprehensive index methods of Nemerow index,minimum operator,and weighted average were improved and applied flexibly to evaluate the drinking water quality in ten residential communities in Changning District of Shanghai in December 2008.[Results] The integrated index values of drinking water samples were in the range of 0.34-1.26,significantly lower than the drinking water supplied in the municipal network.The main factors influencing the drinking water quality were pH,turbidity and chemical oxygen demand(COD).[Conclusion] The quality of drinking water in Changning District is comparatively better than the municipal water supply network,but some indices require special attention.
