Abstract
PURPOSE: To decompose and remove indecomposable organic pollutants, complex cyan, etc. efficiently by a method wherein waste water is aerated with ozone, hydrogen peroxide is injected and the waste water is aerated with ozone.
CONSTITUTION: Waste water is injected into a reaction tank 1 from an injection port 2 and received, ozonizing gas from an ozone generator 4 is jetted from a gas disperser 5, and a rate of absorption of ozone n, which is approximately 100%, decreases with the lowering of the concentration of decomposable substance. When an ozone monitor 10 detects the lowering of the rate of absorption n to 90W95%, hydrogen peroxide in quantity previously decided from pollutants, the set value, etc. of the rate of absorption of ozone n is injected. When TOD, COD and TOC satisfy regulating value, aeration with ozone is stopped, and treated water is discharged by opening an extracting port 3. A pH monitor 7 monitors the pH of the waste water, and an alkaline agent is injected from an alkaline agent storage tank 9 so that the pH be kept in neutrality or alkalinity.
