| 摘 要： | 地下水氟来源是防氟改水的重要基础之一。通过水文地质调查,查明了吉林通榆氟中毒区地下水中氟的来源。大兴安岭来源是地下水中氟来源的主体,地下水含水介质和围岩释放的氟均是富集了大兴安岭来源的再释放。研究区含水介质中可溶性氟含量为3.15～8.00 mg/kg,围岩可溶性氟含量为5.2～10.4 mg/kg。1984～2006年,地下水氟含量有升高现象。根据研究区地下水资源特点,选择5个示范井,进行防氟改水,将上第三系大安组含水层作为目的水层,水中氟浓度符合生活饮用水质标准。 |

| Abstract: | The source of fluoride in groundwater was one of the basis of to prevent fluoride and to improve the groundwater quality.Through the hydrogeology investigation,the fluoride form the Daxing’anling Mountain was the main source of fluoride in groundwater.The fluoride from hydro-medium and wall rock was an again-release of fluoride which was enriched.The content of dissolved fluoride in hydro-medium was 3.15-8.00 mg/kg,and 5.2-10.4 mg/kg in wall rock.From 1984 to 2006,the content of dissolved fluoride had been increasing.Through the character of groundwater resource in study area,five example wells were selected,making the Neozoic Daan Formation groundwater as the aim aquifer to improve the drinking water for fluoride prevention,and the fluoride concentration conformed to drinking water sanitary standard. |
