<p>PURPOSE:To improve the oxygen dissolution efficiency of waste water by making the water contact with oxygen in the dropping process from the flow regulating plate to the module. CONSTITUTION:The original waste water introduced from the line P1 is flowed down in the module 2 through the regulating plate 6 by air lift pumping of the diffuser 4. The waste water from the air-exposing chamber 3 is divided by many holes of the regulating plate 6 and drops to the upper part of the module 2. In the dropping process from the plate 6 to the module 2, the water is made contact with gas, which contains oxygen, from the line P4 to improve the oxygen dissolution efficiency in the waste water. The gas is discharged from the exhaust port 7 after contact with the waste water.</p> |
