METHOD FOR REMOVING CONTINUOUSLY IONS IN ORGANIC SOLID WASTE RESOURCES USING ELECTRIC FIELD

摘要

PURPOSE: A method for continuously removing metal/salt ions in organic solid waste resources such as sewage sludge and garbage using electric field is provided to recycle waste resources as fertilizer and soil conditioner. CONSTITUTION: The method comprises the steps of (a) applying a current ranging from 0.001 mA/cm¬2 to 1000 mA/cm¬2 to electrolyte in an organic solid waste resources using a direct current (DC) supply device wherein a positive electrode is connected to a screw axis(4) and a negative electrode is connected to a screw conveyer cover(11), (b) trapping negative ions at the positive electrode connected to the screw axis and positive ions at the negative electrode connected to the screw conveyer cover.
