PURPOSE: An ultrasonic wave generator a wastewater treatment system, and a wastewater treatment method are provided to save energy by changing the flow path in a disinfecting chamber or a discharge tub. CONSTITUTION: A wastewater treatment system, a screen tank, a water collection bath, a reaction bath, a first precipitation bath, an aeration bath, a second precipitation bath, and a disinfecting bath. The reaction bath coagulates an organic material and suspended material by the reaction of wastewater from a water collection bath and chemicals. The second precipitation bath removes precipitated active sludge by digesting organic materials. The disinfecting bath generates ultrasonic waves to remove bacteria in the treatment water transferred from the second precipitation bath. The disinfecting bath includes a treated water inlet part (710); a treated water outlet part (730); and a plurality of partition walls (720). The partition walls forms a path for the treated water transferred from the second precipitation bath. |
