Abstract

PURPOSE: To improve the adsorption rate and adsorption capacity and keep adsorption efficiency for a long duration by providing an adsorption tank to store a mixed slurry, a supplying pipe of water to be treated, a membrane separation unit, a sucking pump, an air bubbling pipe, and a blower communicating with the air bubbling pipe.
CONSTITUTION: Regarding an activated carbon adsorbing apparatus, air 24 is supplied to an air bubbling pipe 21 by a blower 23 to carry out aeration of a mixed slurry consisting of water to be treated 14 and activated carbon powder 15 stored in the inside of an adsorption tank 11. Uprising stirring current generated by the air lifting function of the aerating air 24 ascends the mutual gaps of membrane modules and thus circulating current is generated in the tank 11 wherein the current consists of upward current flowing upward from down side in the inside of a membrane separation unit 16 and downward current flowing downward from upper side in the outside of the membrane separation unit 16. While the mixed slurry 12 in the adsorption tank 11 whirls by circulating current, COD of the water to be treated 14 is removed and water is decolored by adsorption by the activated carbon powder 15.
