WASTEWATER PURIFYING PROCESS USING COMBINATION OF ULTRASONIC WAVE, OZONE, HIGH-FREQUENCY WAVE AND ULTRAVIOLET RAY

摘要

PURPOSE: A wastewater purifying process using combination of ultrasonic wave, ozone, high -frequency wave and ultraviolet ray is provided, which can remove nitrogen, phosphorus and organic matter contained in livestock wastewater, excrement, leachate and leather industry wastewater, color and odor gas easily. The system can also diminish the required area of plant construction. CONSTITUTION: The system comprises the followings: (i) an ozone and ultrasonic wave reaction tank (3) for removing impurities contained in wastewater; (ii) a high-frequency wave reaction tank (4) in which high-frequency wave polar plates are installed for irradiating high-frequency wave; and (iii) a settling tank (6); and a combined reaction tank (8) in which an agitator is installed and ultraviolet ray and ultrasonic wave are irradiated and ozone is dissolved for removing the residue organic matter.
