The invention discloses a resourceful treatment method for chemical sludge. The resourceful treatment method comprises steps as follows: sludge obtained after sewage treatment of a paper mill is divided into two parts, one part is subjected to drying, smashing, screening and carbonization, and a porous solid is obtained; the other part is subjected to acid-adding dissolving, oxidization and filtering, and a filtrate is obtained; the porous solid is put in the filtrate and soaked for 2-4 h, evaporation is performed, all moisture is removed, and particles are obtained after breaking; the particles can be used for removing phenol. The more appropriate mass ratio of the two parts is 1:(1.2-1.5), when the mass ratio is 1:1.3, that is, when the mass ratio of the part for acquisition of the porous solid to the part for acquisition of the filtrate is 1:1.3, the resource utilization rate is the highest.
