(57) [Summary] [Problem] To make the polluted rivers and lakes water harmless, The detoxified residue material is floated on the water surface, and is removed by suction so that it can be treated on the ground. SOLUTION: Contaminated water and air collide with a ceramic ball 15 in a ceramic ball storage cylinder 9 of a suction pressure feeding section 4 to take in negative ions into bubbles. Then, the water is introduced into the contaminated water and gas-liquid mixing section in that state, and collides with the magnet rod 39 and the ceramic rod 40 which are arranged to protrude into the distribution water passage 20, and each blade section 19 Turbulence is generated in the right-angle recesses 28 to 30 in a to 19c to form superfine bubbles, which are formed by the annular openings 32 of the diffusion plate 22, and are drained to rivers and lakes. |
