METHOD FOR TREATING SLUDGE USING IONIZATION GAS AND NATURAL CONDITIONER SUCH AS LOESS AND ZEOLITE

摘要

PURPOSE: To provide a method for treating sludge using an ionization gas, which is able to improve the dehydration capacity of the sludge treated by the ionization gas and reduce cake generated by the dehydration of the sludge to soil. CONSTITUTION: The method comprises the steps of: (a) thickening sludge; (b) treating the thickened sludge using ionization gas to annihilate micoorganism, decrease solid matters and remove nutritive salts of recycled water; and (c) adding a natural coagulant such as loess to the sludge to dehydrate the sludge.
