The one of the important physical factors impacting on the environmental safety of industrial wastewater generated in the production of paints and varnishes is considered. Identification wastewater formation sources, composition, its amount in a particular type of resin is an essential point for developing methods of cleaning industrial wastewater treatment design and industrial plants. Deep cleaning of wastewater from phenol is a major challenge. Studies that mostly focused on the known methods of disposal of waste waters from phenol have been analyzed. It was shown that the shortcomings of many methods of sewage treatment of phenols by condensation at atmospheric pressure are the long duration of the process, significant cost of heat, and large residual phenol concentration in water, respectively. The most effective method of reducing the concentration of phenol in waste water is its oxidation in MnO2 suspension. The interaction of manganese oxides with sulfuric acid produces oxygen, which can oxidise phenol contained in the waste water. As a result of wastewater treatment of phenolic resins by manganese oxides in acidic sulfate medium phenol concentration  was decreased by 98.6 - 99.6%.
