摘要

砷和氟自然存在于地下水中,特别是在沙漠和半沙漠地区。通过饮用水长期接触这些物质会对健康造成不利影响,而这些物质在供人类饮用的水中是有限的。目标:开展这项工作的目的是改善砷和氟含量高的水井的水质,使其符合《墨西哥饮用水条例》规定的限值。方法:使用双面板太阳能蒸馏系统处理来自三口井的水,这些井的砷和氟化物含量高,供人类饮用。贡献:所使用的太阳能蒸馏系统通过去除砷(99%)、氟化物(96%)和溶解固体(98%)改善了地下水的质量。经过验证的系统是小型社区水处理的可行替代方案,这些社区无法获得成本高昂的脱矿水厂,从而消除了与长期摄入这些元素相关的健康风险。

Utilización de un sistema de destilación solar para remoción de Arsénico y Flúor en agua subterránea destinada al consumo humano
Arsenic and fluorine occur naturally in groundwater, especially in desert and semi-desert areas. Chronic exposure through drinking water to these substances causes adverse health effect, which are limited in water intended for human consumption. Objective: This work was carried out with the aim of improving the quality of water from wells with high contents of arsenic and fluorine, achieving compliance with the limits established in the Mexican regulations for drinking water. Methodology: A system of two-panel solar distillation was used for treatment of water from three wells characterized by high levels of arsenic and fluoride, which are intended for human consumption. Contribution: The solar distillation system used improved the quality of the groundwater through the removal of arsenic (99%), fluoride (96%) and dissolved solids (98%). The proven system is a viable alternative for water treatment in small communities that do not have access to demineralization water plants that operate with high costs, thus eliminating health risks associated to the chronic intake of these elements.
