目的 了解连云港市市政供水的卫生状况,为加强市政供水卫生监督管理工作提供科学依据.方法 对收集的连云港市2008-2015年市政供水水质监测资料进行统计分析,主要分析出厂水、末梢水中感官、一般化学指标、毒理学指标、细菌学指标、放射性指标及消毒剂指标的合格情况,并比较出厂水和末梢水合格的情况.结果 2008-2015年市政供水合格率为36.01％.不同季度中水质的合格率不同,以第3季度最低,主要不合格项为一般化学指标和毒理学指标,尤其是耗氧量和氟化物;末梢水的合格率低于出厂水,且其感官及细菌指标的合格率远低于出厂水.结论 2008-2015年连云港市政供水合格率偏低,尤以第3季度为著,末梢水的合格情况较出厂水下降.“,”Objective To learn the hygienic status of the municipal water supply in Lianyungang so as to provide a scientific basis for strengthening its supervision and management.Methods The surveillance data of the municipal water supply were analyzed,mainly including sensory,chemical,toxicological,bacteriological,radical and disinfectant indices in tap or peripheral water from 2008 to 2015,and the over-standard rates of the tap and peripheral water were compared.Results The qualified rate of municipal water supply was 36.01％ from 2008 to 2015.The qualified rate of water varied in different seasons and was the lowest in the third season.The main non-conforming items were chemical and toxicological indices,particularly oxygen consumption and fluorides.The qualified rate of peripheral water was lower than that of tap water,and the qualified rates of sensory and bacteriological indices were far lower than those of tap water.Conclusion The quality of municipal water supply in Lianyungang was poor from 2008 to 2015,especially in the third season.The quality of peripheral water is lower than that of tap water.
