AERATION TREATMENT METHOD FOR CONTAMINATED WATER AND AERATION TREATMENT DEVICE FOR CONTAMINATED WATER

摘要

To provide an aeration treatment method for contaminated water and aeration treatment device for contaminated water with a hydrophilic solvent for effective purification by using a small aeration treatment tank without requiring large energy.SOLUTION: The method includes storing a contaminated water contaminated with a hydrophilic solvent in a sealed aeration tank, aerating by injecting microbubbles into the contaminated water, and adding an oxidizing agent before aeration or during aeration to promote the oxidation of the hydrophilic solvent contained in the contaminated water and float an intermediate product or a final product produced in the contaminated water to the upper part in the aeration tank by the microbubbles, and discharging gas containing the intermediate product or final product to the outside of the aeration tank to promote purification of the contaminated water.SELECTED DRAWING: Figure 1
