Abstract:

An improved physicochemical method is used to treat the grey water from paper-making and improve the efficiency of treatment. The result proved that the pretreating for grey water with a new type of effective flocculant can remove SS、ＣＯＤ_Ｃｒ and chromaticity effectively, from which satisfactory results have been obtained.

Key words: grey water from paper-making, physicochemical treatment
