【摘要】 目的检测分析2015-2018年高安市生活饮用水水质卫生状况及变化趋势,为相关部门加强居民饮水安全管理提供科学依据。方法在2015-2018年期间,依据GB/T 5750—2006《生活饮用水标准检验方法》和GB 5749—2006《生活饮用水卫生标准》采用网格布点法进行水样的采集和检测,共检测水样779份,对全市生活饮用水水质卫生状况进行监测及分析并对水质结果做出评价,并建立对应的数据库,用SPSS 22.0进行统计分析。结果水样合格率饮用集中式供水(84.47%)高于饮用分散式供水(53.39%),差异具有显著性意义(P<0.01);水样合格率城市水(86.00%)高于农村水(62.27%),差异具有显著性意义(P<0.01);影响指标不合格的因素主要为供水方式和水源类型。结论高安市饮用水安全问题不容乐观,总体水质合格率低,特别是农村自来水存在明显的问题;市政府应加大对饮用水的管理力度,确保高安市生活饮用水安全,重点是农村地区,需实施改进措施。更多还原

【Abstract】 Objective To detect and analyze the drinking water quality,sanitary status and changing trend in Gao’An City from 2015 to 2018,and to provide scientific basis for relevant departments to strengthen the safety management of drinking water for residents. Method During the period of 2015 to 2018,779 samples were collected and tested by grid distribution method according to GB/T 5750—2006 Standard Inspection Method for Drinking Water and GB 5749—2006 Standard for Drinking Water Hygiene. The drinking water quality andsanitation in the city was monitored and analyzed,and the results were evaluated. The corresponding database was established by SPSS. 22.0 for statistical analysis. Result The qualified rate of drinking centralized water supply(84.47%) was higher than that of drinking decentralized water supply(53.39%) with significant difference(P<0.01);the qualified rate of urban water(86.00%) was higher than that of rural water(62.27%) with significant difference(P <0.01);the main factors influencing the unqualified indexes were water supply mode and source type. Conclusion The safety of drinking water in Gao’An City is not optimistic,and the overall qualified rate of water quality is low,especially the rural tap water has obvious disadvantages. Municipal government should strengthen the management of drinking water to ensure the drinking watersafety in Gao’An City,focusing on rural areas and implementing improvement measures.更多还原
