FIELD: process engineering.
SUBSTANCE: invention relates to applied ecology and can be used in chemical industry, metallurgy and various braches of machine building for cleaning industrial effluents from heavy metal ions and oil products. Proposed method comprises treating saw dust by modificators and drying. Bentonite clay makes said modificator. Treatment comprises mixing said bentonite clay, water and saw dust in the ratio of 1:2:1, drying obtained mix at 115-125°C for 3.5-4 h, powdering to fractions of 3-15 mm, and thermal treatment at 145-155°C for 2-2.5 h.
EFFECT: expanded applications, reduced process time and costs.
