摘　　要：为了解青岛市农村地区生活饮用水的水质状况,为农村居民安全的使用饮用水提供参考,本文以青岛市崂山区、城阳区、即墨市周边农村的生活饮用水为研究对象,进行水样采集和测定,水质监测项目包括:总溶解固体含量、总硬度、碱度、CODMn、硫酸根含量、氯离子含量、金属离子(Pb、Fe)含量及亚硝态氮等。依据《生活饮用水卫生标准》(GB5749-2006)对测定结果进行分析。结果表明:水样中氨氮、总溶解固体量小于标准限值,其它指标均存在超标情况,CODMn的超标率最高,可达39.1%,其次是硫酸盐和铁含量,分别为35%和34.8%。硫酸盐的超标倍数最大,超过国家标准值的52倍。建议加强对农村水质进行监控,改善饮用水的品质,提高农村居民的饮水质量。The water samples collected from Laoshan District ,Chengyang District and Jimo City in Qingdao were measured to understand the water quality of rural drinking water sources in the area and provide some reference for using the water safely .The monitoring project of water quality includes the content of total dissolved solids ,total hardness ,alkalinity ,permanganate index of oxygen demand （CODMn ） ,sulfate radi-cal content ,chloride ion content ,Metal ion （Pb and Fe） content and nitrite nitrogen content .The meas-ured results were compared with the criterion listed in Standards for Drinking Water Quality （GB5749 -2006） .The results showed that the contents of ammonia nitrogen and the total dissolved solids were less than that of standards .The over-limit ratio of CODMn ,topped out at 39.1% ,was the highest one ,and it was followed by that of sulphate and Fe ion contents ,with peak values of 35% and 34.8% respectively . The superstandard multiple of sulphate was the highest and was up to 52 to the national standard value . According to the results ,something must be done to reinforce the monitor of the rural water quality and improve the quality of the drinking water .
