Abstract: The wastewater of the wood-based industry contains toxic phenols that exceed the maximum allowable values. There is little data on the methods of purification of wastewater of woodworking plants from aromatic compounds and their derivatives in the literature. Therefore, the authors investigated the different effect of ozone on the wastewater of the Ufa plywood-slab plant for the purpose of purification. The flocculating effect of ozone and the physicochemical method (coagulation and flocculation) of wastewater treatment were investigated. The use of ozone in the first stage of wastewater treatment allows reducing the concentration of suspended substances to the required level with the help of an environmentally friendly method and preparing wastewater for oxidative purification from toxic substances. The suggested method is not only more environmentally acceptable, but also more economically reasonable, because reagent acquisition costs are excluded.
