METHOD OF REMOVING DIOXINS IN WASTE WATER

PROBLEM TO BE SOLVED: To provide the method of removing dioxins in waste water which is capable of removing the dioxins in the waste water upto a concn. as low as possible. SOLUTION: The waste water from the dumping site exudation water treating device at a rubbish final disposal site and various kinds of industries is stored in a waste water tank 1 at an existing waste water treating equipment, then the waste water is sent to a chemical mixing tank 2 to add a flocculating agent, etc., then the waste water is sent to a flocculating and settling tank 3 to remove precipitated matter. Then the waste water is sent to a neutralizing tank 4 and made to pass through a sand filter column 5 then stored in a discharge tank 6, and discharged to out of system as required or reused. At the time of executing the removing method of the dioxins in the waste water, the waste water passing through the send filter column 5 is treated at a membrane separation device 7, and water permeating the membrane is made to pass through an activated carbon adsorption column 8 to be subjected to adsorption treatment, and the treated water finally is returned to the original line of the existing waste water treating equipment before the discharge tank 6.
