Abstract

The invention provides a Fenton catalyst and a preparation method thereof. In combination with a rolling granulation preparation process, a high specific surface area, uniform pore size distribution and a proper pore volume of the catalyst can be guaranteed, meanwhile, metal element and boron element doping is combined, the boron element can change the surface performance of the catalyst and forma synergistic effect with other metal active ingredients, the specific surface of the catalyst can be guaranteed to the maximum extent through a further rolling granulation method, the effect of the boron element is brought into play to the maximum extent, and then the catalytic activity of the Fenton catalyst is integrally improved. In addition, active components are uniformly doped inside and outside the activated aluminum oxide through rolling granulation, and can be uniformly and continuously released, so that the service life of the catalyst is prolonged, and industrial application and promotion are facilitated, furthermore, the material is integrally prepared, the preparation process is simple, the production cost is low, and the material is suitable for industrial production and application.

Description

technical field [0001] The invention relates to the technical field of catalyst preparation, in particular to a Fenton catalyst and a preparation method thereof. Background technique [0002] At present, with the continuous deepening of industrialization, the discharge of industrial sewage continues to increase, resulting in increasing environmental pollution. Moreover, domestic chemical companies continue to subdivide industrial content, diversify production processes and refine industrial products, resulting in complex components of industrial sewage pollutants, a wide variety of organic substances with large content, high toxicity and refractory biodegradation. In addition, with the continuous increase of national environmental protection supervision and stricter pollutant discharge indicators, the biological method cannot fully meet the treatment goals. Fenton oxidation is an important part of advanced oxidation technology. Due to its characteristics of simple operation...
