A OZONIZE FILTRATION TYPE WASTE WATER PROCESS METHOD AND A WASTE WATER DISPOSAL APPARATUS THEREOF

摘要

PURPOSE: An ozone filtration water treatment method and ozone filtration water treatment apparatus are provided to treat various contaminants contained in effluent and simplify water treatment process and facility so that not only installation space and treatment time are reduced, but also facility cost and operation cost are reduced. CONSTITUTION: The apparatus comprises a filter chamber(110) in which filter element is installed to remove foreign materials in effluent; a main pump(170) installed on effluent supply pipe to transfer effluent into the filter chamber; a coating solution preparation means(120) into which certain quantities of subsidiary filtering agent and cleaning solution are injected and mixed to form coating solution so that the coating solution is transferred into the filter chamber by the main pump to form a precoating layer on the filter element; an ozone and hydrogen peroxide supply unit(130) installed on the supply pipe of the effluent supplied into the precoating layer formed filter chamber so that a mixture of ozone and hydrogen peroxide is supplied into the ozone and hydrogen peroxide supply unit; a purified water tank(140) in which filtered water separated from the filter chamber is stored, and which comprises an ozone discharge unit for discharging ozone contained in the filtered water; a slurry tank(150) positioned at a lower part of the filter chamber so that slurry separated by the filter element is discharged and stored in the slurry tank; a dehydrator(160) for solid/liquid separating the slurry transferred from the slurry tank by slurry supply pump; and a compressed air supply unit(180) for supplying compressed air to the filter chamber, dehydrator, coating solution preparation means, purified water tank and slurry tank that are connected to the compressed air supply unit under controlling of control part so as to perform discharge of slurry and cake, mixing of subsidiary filtering agent and aeration.
