THE APPURATUS OF REMOVING TOTAL PHOSPHORUS IN WASTEWATER USING OXIDAITION PROCESS

摘要

PURPOSE: An apparatus for removing dissolved phosphorus in water waste is provided to remove the dissolved phosphorus using an oxidant process to react to the phosphorus with a coagulant and maximize the removing rate of the entire phosphorus. CONSTITUTION: An apparatus for removing dissolved phosphorus in water waste and treating tub(20) before oxidation, a reacting tub(30) and a solid-liquid separating tub(40). No diaphragm electrolysis cell is comprised between the treating tub before oxidation and the reacting tub. The treating tub before the oxidation puts the hydrogen peroxide and the ion salt from inflowing water and keeps the pH at 3-5 by putting into a pH modifier. The reacting tub makes phosphorus cohesive by putting a coagulant into treated water which is oxidized. To separate a solid particle from the treated water, a micro bubble generating apparatus is equipped in the solid-liquid separating tub. The micro bubble generating apparatus comprises a collecting tube, an air sucking tube and an impeller. The collecting tube is equipped in the lower surface to form space inside. The air sucking tube connects the inside of the collecting tube to the outside of the solid-liquid separating tub.
