Abstract

Method for purifying lignin-containing effluents from wood industries and related industries where cellulose-containing products, especially effluents from chemical wood pulp mills, are used for separation and destruction of the lignin content, characterized why the effluent is treated with a porous and granular phenolic resin that traps the lignin contained in the water; because the resin elutes; because it is carried out in the industry, properly speaking, and the eluted liquid contained in the lignin concentrate is destroyed in it; and because the effluent that has been released practically from lignin is discharged through an outlet pipe or recirculated.
