<p>PROBLEM TO BE SOLVED: To provide a water cleaning system capable of effectively cleaning water in rivers or a basin. SOLUTION: A water cleaning system P has a water cleaning apparatus A and an air generator B and the water cleaning apparatus A has an apparatus body part A1, a filter medium unit suspending part A2 and filter medium units A3. An air diffusing plate 24 is provided to the bottom part of the discharge pipe part 20 of the apparatus body part A1 and a hole part 22 is provided to the side wall of the discharge pipe part 20. The air generated by the air generator B is discharged into water from the air diffusing plate 24 to move upwardly. Whereupon, a large convection can be formed by the fine air bubbles discharged from the air diffusing plate 24, the hole part 22 provided to the side wall of the discharge pipe part and an air diffusing part 50 formed into a semispherical shape, and the growth of bacteria in the filter medium 102 of each filter medium unit A3 can be accelerated.</p> |
