Water pollution is one of the main causes imbalance in Earth's ecosystem.Plant effluents have different compositions and concentrations pollutants, depending on kind production water supply sewerage system.The sources phenol-containing wastewater are coking plants, coke oven gas semi-coking generating stations, wood heat treatment synthesis artificial liquid fuels.They can also be result activities metallurgical oil refineries, enterprises for recovery rubber, film, phenolphthalein, salicylic acid, salol.Phenolic waters dangerous fishery reservoirs, worsen organoleptic properties water, disrupt natural processes self-purification.Water contaminated with phenolic contributes to deterioration groundwater quality.Thus, high-quality purification from phenol reduce/maximum prevent ingress phenols into industrial drinking an urgent problem.Methods deep regenerative destructive.The technology purifying using oxidation compounds atmospheric oxygen heterogeneous catalysts most promising technologies.Nanodisperse used treat containing aromatic hydrocarbons and, particular, compounds, should provide a high rate efficient wide range various functional groups, low cost, long service life without noticeable loss catalytic properties, as well mechanical strength immunity poisons.Catalysts based metals metal oxides carrier-based systems, oxide-based magnetic composites show good efficiency oxygen.
