PURPOSE:To obtain a small-sized treatment device utilizable even in a small factory low in the drain amt. of raw water by incorporating a flocculation treatment tank, a cartridge type filter and a mixed bed type ion exchange tower housing an anion exchange resin and a cation exchange resin in a mixed state in one frame. CONSTITUTION:In a waste water treatment device, at first, raw water is allowed to flow in a flocculation treatment tank 1 and a predetermined amt. of a flocculant is fed in the tank 1 to form flocs. The water to be treated containing flocs is sent to a cartridge type filter 2 to be filtered. The water to be treated from which flocs are removed is sent to a mixed bed type ion exchange tower 3 having anion and cation exchange resins received therein in a mixed state and a dissociating fluorine type surfactant and other ions are removed and treated water almost near to pure water, generating no discharge problem and reutilizable as water is obtained. The flocculation treatment tank 1, the cartridge type filter 2 and the mixed bed type ion exchange tower 3 are incorporated in one frame 6. |
