<p>PURPOSE:To enable the miniaturization of a water purifying apparatus, the reduction of operation cost and the stable supply of water of good quality by purifying the biologically filtered soln. of the filter bed having an intake pipe net embedded therein arranged in a water purifying basin with ozone and returning a part thereof. CONSTITUTION:This ozone water purifying apparatus equipped with a water purifying basin l is equipped with a water collection part 13 and a purifying part and the water collection part 13 is equipped with the filter beds 3, 4 arranged in the water purifying basin 1 and the water intake pipe net 19 embedded in the filter beds 3, 4 and an ozone contact device 30 is provided to the water purifying part. The ozone contact device 30 is equipped with a secondary ozone contact tank 43 bringing ozone led out of an ozonizer 31 into contact with a vertical circulating soln., a secondary ozone contact tank 43 bringing waste ozone led out of the tank 32 into contact with the vertical circulating soln. and a tertiary ozone contact tank 54 bringing waste ozone led out of the tank 43 into contact with the vertical circulating soln. The ozone contact tanks 32, 43, 54 are equipped with falling pipes 33, 44, 68 and rising pipes 36, 48, 72 communicating with each other at the upper and lower parts of them to form a vertical circulating. circuit.</p> |
