Description
Technical Field
The invention relates to the field of environment-friendly medicaments, in particular to a formula of a hypochlorous acid oxidation catalyst.
Background
Hypochlorous acid oxidation technology is widely applied in the industrial field, and is particularly common in the field of water treatment. There have also been many researchers studying catalysts that catalyze their decomposition, but the hypochlorous acid decomposition rate is improved, but the removal of the metal complex is not thorough. If the hypochlorous acid oxidation method is adopted, the decomposition of the hypochlorous acid is accelerated by adding the catalyst, and the degradation of the metal complex is accelerated by increasing the collision of free oxygen generated by the catalyst and the metal complex.
The existing catalyst formula only accelerates the decomposition of hypochlorous acid, and does not consider the problem that the collision probability of a metal complex and a catalyst is small at low concentration. The need for new catalyst formulations is therefore apparent.
Disclosure of Invention
The invention aims to solve the technical problem of providing a formula of a hypochlorous acid oxidation catalyst, and aims to solve the problem of incomplete treatment of metal complex wastewater.
In order to solve the technical problems, the invention adopts the following technical scheme: the formula of the hypochlorous acid oxidation catalyst comprises the following components in parts by weight: 30-50 parts of nickel oxyhydroxide, 10-30 parts of nickel chloride, 20-60 parts of calcium chloride, 10-20 parts of magnesium chloride, 10-30 parts of polyaluminium chloride and 10-30 parts of polyacrylamide. The hydroxyl nickel oxide and the nickel chloride form a cycle in the catalytic oxidation process of hypochlorous acid, and the oxidative decomposition of the hypochlorous acid is accelerated. Calcium chloride and magnesium chloride form a skeleton adsorption effect to adsorb trace metal complexes, and then catalytic groups and adsorption groups are gathered together through micelles formed by polyaluminium chloride and polyacrylamide, so that the oxidation of the trace metal complexes is improved, and the removal rate of the metal complex wastewater is improved.
