摘要 为了解青岛市农村地区生活饮用水水质的情况,为该地区居民健康安全地使用饮用水提供参考,本试验以青岛市崂山区、城阳区、即墨市农村生活饮用水为研究对象,根据各地生活饮用水水源供给途径等进行采样点布设和水样采集,对所采水样进行金属离子(Pb、Fe)、总溶解固体含量、pH值、总硬度、碱度、CODMn、氨态氮、亚硝态氮、硫酸根及氯离子含量等测定,采用主成分分析法对其水质进行综合评价。结果显示:青岛市农村饮用水水质问题主要是总硬度、氯化物含量、硫酸根含量、CODMn含量和溶解性总固体TDS含量高;即墨市各采样点水质较差,其次是城阳区,崂山区采样点水质最好。建议加强农村饮用水尤其是工业企业密集的农村水源保护,保障农村饮用水水质卫生安全。 To know about the quality of Qingdao rural drinking water and provide some references for safely using the drinking water , the water samples collected from Laoshan District , Chengyang District and Ji-mo City were studied by principal component analysis .The monitoring projects of water quality included pH value, total hardness, alkalinity, the contents of metal ion (Pb and Fe), total dissolved solids, CODMn, sul-fate radical , chloride ion , ammoniacal nitrogen and nitrite nitrogen .The results showed that the water quality problems were mainly embodied in higher contents of total hardness , chlorides, sulfate radical, CODMn and to-tal dissolved solids .The water quality of Jimo City was the worst followed by Chengyang District , and that of Laoshan District was the best .It was suggested that the rural drinking water sources especially located in the dense industrialized regions should be strongly protected to ensure the rural drinking water security .
