Abstract: A water pollutant processing method to adsorb, oxidize and activate water pollutants includes using an adsorbent with low oxidation number (zeolite), an activator (from industrial wastes, such as BF slags and BOF slags) and a persulfate to process polluted water and underground water. The method includes an integrated processing system including the persulfate, adsorbent with low oxidation number and iron-containing activator. The integrated processing system not only possesses an adsorbing capability, but also an oxidizing capability using transition metal such as iron on the surface of the activator. The system can not only accelerate removal of water pollutants, but also delay movement of the pollutants to further reduce threat of pollutant spreading to downstream. BF and BOF slags are industrial wastes and the present invention also provides a channel for reusing the wastes.
