摘　　要：目的了解并掌握中山市生活饮用水出厂水水质的卫生状况,为改善生活饮用水水质提供科学依据。方法采用定期抽样的方法,每季度对中山市城区和各镇区的生活饮用水出厂水进行采样分析,分析研究的项目类别主要包括毒理指标(砷、镉、6价铬、铅、汞、硒、氰化物、氟化物、硝酸盐、三氯甲烷、四氯化碳、三氯乙烯、四氯乙烯、马拉硫磷、对硫磷、甲基对硫磷、乐果、敌敌畏、苯、甲苯、二甲苯、乙苯、苯乙烯、毒死蜱等)、感官性状和一般化学指标(色度、浑浊度、臭和味、肉眼可见物、pH值、铝、铁、锰、锌、铜、氯化物、硫酸盐、溶解性总固体、总硬度、耗氧量、挥发酚类、阴离子合成洗涤剂等),放射性指标(总α放射性、总β放射性等)、微生物指标(菌落总数、总大肠菌群、耐热大肠菌群、大肠埃希菌等)和消毒剂常规指标(游离氯、总氯等)。结果分析评价的生活饮用水出厂水水质共309份,所检项目全部达到国家《生活饮用水卫生标准》(GB5749-2006)的共289份,达标率为93.5%。结论中山市城区和各镇区的生活饮用水出厂水水质卫生质量总体较好,但相关部门也要全方位地对供水质量保持高度重视,确保供水的卫生与安全。[Objective]To learn the hygienic quality of drinking water in Zhongshan city,provide the scientific basis for improving the drinking water quality.[Methods]With periodic sampling,drinking water in urban area and every town of Zhongshan city were sampled and analyzed every season.The types of analysis items included toxicological parameters（arsenic,cadmium,hexavalent chromium,lead,mercury,selenium,cyanide,fluoride,nitrate,trichlormethane,carbon tetrachloride,chlorylene,tetrachloroethylene,malathion,parathion,methyl parathion,dimethoate,dichlorvos,benzene,toluene,xylene,ethyl benzene,styrene,chlorpyrifos,etc.）,organoleptic and general chemical parameters（color,turbidity,odor and taste,macroscopic substance,pH value,aluminum,iron,manganese,zinc,copper,chloride,sulphate,total soluble solid,total hardness,oxygen consumption,volatile phenols,anionic detergents,etc.）,radioactivity parameters（general alpha radioactivity,general beta radioactivity,etc.）,microbiological parameters（total bacteria count,total coliform bacteria,thermotolerant coliform bacteria,escherichia coli,etc.） and disinfectants parameters（free chlorine,total chlorine,etc.）.[Results]309 samples of drinking water were evaluated,and 289 samples met the requirements of the Drinking water sanitary standard（GB 5749-2006） for all items,with the standard-reaching rate of 93.5%.[Conclusion]The hygienic quality of drinking water in urban area and every town of Zhongshan city is good.However,the relevant departments should pay great attention to drinking water quality,in order to ensure the health and safety of drinking water.
