Abstract

The invention provides a preparation method of an ozone oxidation catalyst, the preparation method comprises the following steps: firstly, putting activated carbon into a crusher, crushing by the crusher, then putting the crushed activated carbon into a mesh sieve, screening the activated carbon by the mesh sieve, cleaning the screened activated carbon by clear water for 3-5 times, then putting the cleaned activated carbon into a dryer, drying the cleaned activated carbon by the dryer, and taking and placing sodium sulfate, aluminum sulfate, potassium sulfate, calcium sulfate, sulfuric acid and ferric sulfate respectively on a weighing device. The preparation method of the ozone oxidation catalyst has simple steps and simple and convenient operation, not only can the preparation efficiencyof the ozone oxidation catalyst be improved, but also the prepared ozone oxidation catalyst has better effect, the preparation method provides convenience for people, can meet the needs of people, and can save a large amount of manpower.

Description

technical field [0001] The invention relates to the technical field of catalyst preparation, in particular to a preparation method of an ozone oxidation catalyst. Background technique [0002] At present, the traditional ozone oxidation method is to make a solution of a certain concentration of the catalyst and add it to the waste water. The catalyst will catalyze in the form of ions, and then pass through the ozone to carry out the catalytic oxidation reaction. Although this method can improve the treatment effect of ozone, there are problems in the use of homogeneous catalysts that the catalyst is difficult to recover, and impurities are introduced to cause secondary pollution, which limits its application in water treatment to a large extent. The preparation method of the oxidation catalyst has complicated steps, and the effect of preparing the catalyst is not good, which cannot meet people's needs. Contents of the invention [0003] The technical problem to be solved ...
