摘要
地下水长期接触各类不同的地质条件,溶有大量的金属元素,其中以铁、锰、砷等金属为典型代表。去除地下水中铁锰元素的主要方法有空气氧化法、接触催化氧化法、生物氧化法以及颗粒活性炭吸附法。列举了2座已投入生产实践的生物除铁除锰水厂的运行情况与处理效果,阐明了生物除铁除锰技术在我国的研究与应用水平。对现有的生物除铁除锰研究作出了客观性评价以及对未来研究方向的展望。
Abstract：Due to long-term exposure to different geological conditions, the underground water may contain such mineral elements as iron, manganese and arsenic. This paper firstly reveals some methods for removing iron and manganese including air oxidation, contact catalytic oxidation, biological oxidation and granular activated car- bon adsorption. Then, it analyzes two water treatment plants which have put biological removal of iron and man- ganese into production. Finally it evaluates the existing biological removal of iron and manganese and explores prospects for futureresearch directions.
