| titleOfInvention | Water purification device |
| abstract | [PROBLEMS] To increase purification efficiency. A water purification device (10) that jets water through a water treatment contact material layer (30) and a photocatalyst layer (40) by a submersible pump (15) floating on the surface of a closed water area (P). The water in the reservoir is sucked through the water treatment contact material layer and the photocatalyst layer by the water absorption of the submersible pump, and contaminants in the water are decomposed by the microorganisms attached to the contact material 32 in the water treatment contact material layer. Then, the photocatalytic layer decomposes the hardly decomposable organic substances that could not be decomposed by microorganisms into strong oxidizing action of the optical medium. At this time, since the water that has passed through the water treatment contact material layer 30 is purified by the decomposing action of microorganisms, the oxidizing action of the hardly decomposable organic matter in the subsequent photocatalytic layer is efficiently performed. In other words, the photocatalyst requires light such as sunlight, but since the amount of pollutants has been reduced by the purification at the previous stage, the amount of pollutants attached to the photocatalyst carrier is small, and the transparency of the water has been increased by the purification. In addition, light easily reaches the photocatalyst even in water. [Selection diagram] Fig. 4 |
