Abstract
There is provided a waste water-treating method which comprises passing an aqueous liquid, in an upward direction and at a suitable flow velocity, through a bed consisting of activated carbon whose particle diameter ranges between 0.20 and 1.5 mm and whose width of particle size range (or substantial difference between the largest ones and the smallest ones) is chosen to be 0.30 mm or more, controlling the fluidized bed of the carbon to be expanded 1.2 to 3.0 times to form a particle size gradient of the activated carbon along the resultant fluidized bed.
