目的掌握甘肃省陇南市农村饮用水安全工程水质状况及变化趋势,为今后相关部门制定有效的改水措施提供科学依据。方法按照《生活饮用水标准检验方法》(GB/T5750-2006)中规定,对陇南市所辖9个县的部分农村饮用水安全工程水质在枯水期和丰水期进行了水样的采集和检测,并对结果进行统计分析。结果 2009～2012年共检测水样2 127份,合格1 001份,合格率47.1%,其中枯水期1 055份,合格618份,合格率58.6%;丰水期1 072份,合格383份,合格率为35.7%。结论随着陇南市农村饮用水安全工程不断深入开展,农村饮用水水质状况逐渐改善;影响水质的主要因素是微生物学指标,与水源周围环境的污染和消毒工作开展不到位有关,需采取相应措施加以改善。
Objective To grasp the water quality and trend of rural drinking water safety project in Longnan City of Gansu Province and to provide a scientific basis for the relevant departments to formulate effective water diversion measures in the future. Methods According to the provisions of Standard Test Method for Domestic Drinking Water (GB / T5750-2006), the water quality of some rural drinking water safety projects in nine counties under the jurisdiction of Longnan City was collected and tested during the dry and wet periods , And the results of statistical analysis. Results A total of 2 127 samples of water samples were obtained from 2009 to 2012, with a pass rate of 47.1%. Among them, 1 055 were in dry season, of which 618 were qualified, with a pass rate of 58.6%; 1 072 wet season, 383 pass, The rate is 35.7%. Conclusions As the safety of drinking water in Longnan rural areas continues to deepen, the status of drinking water quality in rural areas gradually improves. The main factors that affect the water quality are microbiological indicators, which are related to the inadequate development of environmental pollution and disinfection of water sources. Measures need to be taken Be improved.
