Abstract

The invention discloses a method for degrading phenol by a solid catalyst. The method is characterized in that a nanometer bimetallic CuCo2O4 catalyst is prepared by a chemical precipitation method; meanwhile, the phenol is degraded into pollution-free CO2 and H2O; when a catalytic oxidation reaction is carried out, the catalyst can efficiently activate potassium peroxodisulfate to generate SO4 and OH; the SO4 and OH have higher oxidation reduction potentials and can be used for directly oxidizing the phenol. Meanwhile, the catalyst CuCo2O4 is good in stability, and still has good catalytic activity after being repeatedly utilized for 7 times; the phenol still can be completely removed. A preparation method of the catalyst, disclosed by the invention, is simple and safe.

Description

technical field [0001] The invention belongs to the technical field of environment and chemical engineering, and relates to the removal of phenol-containing wastewater, in particular to a method for solid catalytic oxidation degradation of phenol. Background technique [0002] In recent years, the increasingly serious environmental pollution has become an important issue in the development of human beings and the sustainable development of society, among which water pollution control is an environmental engineering problem that needs to be solved urgently. At present, my country's rivers, lakes, seas, reservoirs and groundwater are facing different degrees of pollution, and these pollutions are closely related to the illegal discharge of industrial organic wastewater. The serious pollution of water bodies has had a major impact on the environment and the health of residents. With the rapid development of industrial society, the composition of wastewater is becoming more and ...
