目的分析果洛州牧区生活饮用水水质状况,提高牧区牧民的饮水卫生质量。方法 2011年在果洛州所辖的6个县中设立48个监测点,其中集中式供水点37个、分散式供水点11个,分别于枯水期和丰水期各采集水样1次。检测指标有微生物指标、毒理学指标、感官和一般化学指标共19项。水样的采集、保存、检测方法参照《生活饮用水标准检验方法》(GB/T5750-2006)。检测结果判定根据《生活饮用水卫生标准》(GB/T5749-2006)进行。结果共检测水样170份,检测指标均合格的35份,合格率为20.59%,其中微生物指标最低为31.2%,感官和一般化学指标为52.9%,毒理学指标最高为100.0%。结论果洛州牧区生活饮用水合格率太低,尤其是微生物指标,建议加大牧区水利建设,加强牧区饮水安全管理,保障牧区牧民的饮水安全。
Objective To analyze the quality of drinking water in pastoral areas in Guoluo and improve the quality of drinking water in pastoral areas. Methods In 2011, 48 monitoring points were set up in 6 counties under the jurisdiction of Guoluo Prefecture, of which 37 are centralized water supply points and 11 distributed water supply points. Water samples are collected once in dry and wet periods respectively. There are 19 microbial indicators, toxicological indicators, sensory and general chemical indicators. Water sampling, preservation, testing methods refer to “drinking water standard test method” (GB / T5750-2006). Determination of test results based on “drinking water health standards” (GB / T5749-2006). Results A total of 170 water samples were tested, 35 of which were qualified. The pass rate was 20.59%. Among them, the minimum of microbial index was 31.2%, the sensory and general chemical index was 52.9%, and the highest toxicological index was 100.0%. Conclusion The passing rate of drinking water in Guoluo pastoral areas is too low, especially for microbial indicators. It is suggested to increase the water conservancy construction in pastoral areas, strengthen drinking water safety management in pastoral areas and ensure the safety of drinking water for herdsmen in pastoral areas.
