鲁西南高氟区生活饮用水供水模式研究

Study on Drinking Water Supply Mode in High-fluoride Groundwater Areas in Southwest Shandong Province

为有效解决鲁西南高氟区生活饮用水供水安全问题,在水文地质环境地质调查的基础上,通过水质分析、岩土样分析、综合评价研究,查明高氟水的分布规律、圈定生活饮用水找水靶区。结合供水水源空间分布特征、供水现状及供水方式,因地制宜,提出了3种供水模式:以浅层孔隙水或岩溶裂隙水为水源的集中供水模式;以深层孔隙水为饮用水源集中供水并且以浅层孔隙水为生活用水水源的分散供水模式,以及以地表水为主要水源的集中供水模式。供水模式的划分可为鲁西南高氟改水工作及供水安全问题提供技术支持与保障。

In order to ensure the safety of drinking water in the southwest Shandong Province where residents use high-fluoride groundwater as drinking water.Target areas where groundwater matches the drinking water standard was delimited based on hydrogeological survey,analysis of water quality and comprehensive evaluation of water quality.According the water target areas and combing the distribution of other water resource,water supply status and type of water supply,three kinds of water supply modes were developed in different areas.The first one is centralized water supply mode which use shallow porous water or karst fissure water as drinking water and domestic water.The second one is dual water supply mode which use deep porous water as drinking water and supply shallow porous water as domestic water.The last one is centralized water supply mode which use surface water as the main resource of drinking water and domestic water.These water supply modes could be referred by future detailed projects to prevent resident from suffering high-fluoride water.
