摘要: 饮水型氟中毒遍布世界多数国家。中国是发病率最高的国家之一,主要分布在华北、东北及西北地区的部分省、自治区。但目前对于高氟水的处理方法仍然是改水和化学处理,难以解决成本高和二次污染问题。本文以河南省的氟病区信阳市为例进行高氟地下水取样,选取具有代表性的样品,运用温度变化方法进行降氟实验,结果证明在冰冻和煮沸条件下,水中的负离子含量明显下降,基本达到饮用水标准。说明这是一种具有推广价值的降氟方法。但是必须在对其降氟的机理及其病理学影响进行深入研究,有明确结论的情况下方可以推广使用。
Abstract: Fluorosis caused by drinking water happens in many countries around the world. China is one of countries with the highest fluorosis incidence, and fluorosis areas mainly distribute in north, north-east, and parts of northwest of China. Now the treatments for high-fluorine water are still looking for new water source and chemical treatment, these two methods can not solve the problem of high cost and secondary pollution. This paper takes Xinyang City, a fluorosis ward in Henan Province, as an example, samples high-fluoride groundwater, selects representative samples, changes the temperature and tests the fluorine content of the samples, and the results show that under the freezing and boiling conditions, the fluorine content of groundwater samples significantly decreases, can basically meet the drinking water standard. It proves that freezing and boiling groundwater are valuable ways to reduce fluorine, but it still needs further study about the mechanism and the impact of pathology of this method; this method can be widely used with clear conclusions.
