Abstract
PURPOSE: To permit the economical treatment of waste water without replacement of activated carbon by the procedure in which, when a certain amount of sulfur is accumulated in activated carbon in a treatment tank, a caustic soda aqueous solution is used to wash the sulfur in order to reactivate the treating function of the carbon.
CONSTITUTION: By passage of weak current across the carbon electrodes 3 in the treatment tank 2, COD components such as sulfur, thiosulfuric acid ion, etc., present in original water are accumulated in the form of sulfur in the activated carbon 4 between the electrodes 3. Then, when the clarification action of the activated carbon is lowered by the accumulation of more than a certain amount of sulfur, the inflow of the original water is stopped, the original water present inside is discharged, air is blown into the tank from the valve 7, the arrested substances are removed by water from the valve 6, and then a fixed concentration (4W20%) of caustic soda aqueous solution is introduced into the treatment tank 2 to remove the sulfur. Also, when scale, etc., deposit, they are removed by a diluted hydrochloric acid, etc. Thus, without the necessity for replacing activated carbon, the treating function of carbon can be reactivated and waste water can be economically treated.
