目的:通过对农村生活饮用水中铁锰含量的调查与分析,为农村改水工程提供参考依据。方法:按《生活饮用水标准检验方法》(GB/T5750.6-2006)进行水质中铁锰含量分析,按照《生活饮用水卫生标准》(GB5749-2006)中表4《农村小型集中式供水和分散式供水部分水质指标及限值》进行评价。结果:农村集中式供水铁、锰超标率均小于分散式供水;分散式供水每个村东西南北中5份水样中,其中5份铁、锰均超标的为0个行政村。结论:通过加大农村集中供水力度,选好水源、严格管理、定期监测,解决迁安市农村饮水安全问题指日可待。
Objective: To investigate and analyze the content of iron and manganese in drinking water in rural areas and provide references for rural water improvement projects. Methods: According to “Standard Test Method for Domestic Drinking Water” (GB / T5750.6-2006), the content of iron and manganese in water was analyzed. According to Table 4 in Table 4 of “sanitary drinking water standard” (GB5749-2006) Decentralized water supply part of the water quality indicators and limits "for evaluation. Results: The exceeding rates of iron and manganese in centralized water supply in rural areas were all less than those of decentralized water supply. Among the 5 water samples in each village, 5 in iron, manganese exceeded the standard for 0 administrative villages. Conclusion: By increasing the intensity of centralized water supply in rural areas, selecting water sources, strictly managing and regularly monitoring and solving the problem of drinking water safety in rural areas in Qian’an City, it is just around the corner.
