摘要
目的了解市区生活饮用水水质状况及存在的卫生问题。方法对2002-2006年398份水样检测报告进行年度、季节、类型统计分析。结果五年中水样的合格率为36.93%;浑浊度、肉眼可见物、耗氧量在2003、2004、2005年超标率较高;不同季节肉眼可见物、大肠菌群超标率有差异,耗氧量、pH值超标分别集中在一、二季度;浑浊度、耗氧量、细菌总数在不同类型的水中超标情况有显著性差别。结论三门峡城市饮用水常规检验项目超标情况较多,饮用水质量存在一定卫生隐患。
Objective To investigate the drinking water quality and hygiene problems in downtown area of Sanmenxia.
