美刊《水井杂志》1975年10、12月号报导了芬兰处理含铁、锰地下水的方法。该法是在含铁、锰过多的水井周围,打几眼回灌井,将充有氧气的净水回灌注入主井周围的含水层内。充氧净水的作用是一方面增强氧化作用,使地下水中一部分较易溶解的低价铁盐转化为不易溶解的高价铁盐而沉淀在含水层内;另一

The American magazine “Holei Journal” reported in October and December 1975 on the method of treating groundwater containing iron and manganese in Finland. The method is to drill a few recharge wells around wells containing excessive iron and manganese, and pour the clean water filled with oxygen back into the aquifer around the main well. The role of oxygenated water purification is to enhance the oxidation on the one hand and to convert part of the more soluble low-valent iron salts in groundwater into insoluble high-valent iron salts and precipitate in the aquifer;
