充氧回灌地层除铁技术,是将充氧水周期性地注入地层内,使地下水中二价铁转化为难溶的三价铁,在抽取地下水时,三价铁则沉积、截留于地层之中,而达到除铁之目的。 60年代芬兰首创充氧回灌地层除铁技
The technology of removing iron by recharging and recharging formations is to periodically inject oxygenated water into the formation, so that divalent iron in groundwater is converted into insoluble trivalent iron. When groundwater is extracted, trivalent iron is deposited and retained in the formation. In order to achieve the purpose of removing iron.
