Abstract

PURPOSE: To remove the COD component in waste water from desulfurization of waste gas thoroughly, by subjecting said waste water successively to an alkali flocculating and settling treatment, a biological treatment, a filtration treatment, and a treatment with a phenolic synthetic adsorptive resin and a specific weakly basic anion exchange resin.
CONSTITUTION: The pH of waste water from desulfurization of waste gas is controlled to a high alkalinity region and a flocculating agent is added thereto to form floc which is settled and removed. The water is subjected to a biological treatment such as activated sludge treatment followed by a filtration treatment such as ordinary sand filtration or the like. In succession, the water is passed successively through a synthetic adsorptive resin such as a macroporous type resin consisting basically of phenol and a microporous type weakly basic anion exchange resin consisting basically of styrene-divinyl benzene, whereby the water is brought into contact with said resins. Order of the passage may be reversed in this case so as to pass the water first through the weakly basic anion exchange resin.
