Abstract
The invention relates to a catalyst formula for catalyzing oxidation of hypochlorous acid, and particularly relates to a high-efficiency hypochlorous acid catalyst formula. A high-efficiency hypochlorous acid catalyst formula comprises the following components in parts by weight: 30-50 parts of iron oxyhydroxide, 10-30 parts of ferrous sulfate, 20-60 parts of calcium chloride, 10-20 parts of magnesium chloride, 10-30 parts of polyaluminum chloride and 10-30 parts of polyacrylamide. The invention greatly improves the decomposition speed of the hypochlorous acid and accelerates the removal of the complex of the metal.
Description
Technical Field
The invention relates to the field of environment-friendly medicaments, in particular to a high-efficiency hypochlorous acid catalyst formula.
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 has insufficient catalytic efficiency or low recycling rate, so the demand of a novel catalyst formula becomes obvious.
Disclosure of Invention
The invention aims to solve the technical problem of providing an efficient hypochlorous acid catalyst formula and solve the problem of incomplete treatment of metal complex wastewater.
In order to solve the technical problems, the invention adopts the following technical scheme: 30-50 parts of iron oxyhydroxide, 10-30 parts of ferrous sulfate, 20-60 parts of calcium chloride, 10-20 parts of magnesium chloride, 10-30 parts of polyaluminum chloride and 10-30 parts of polyacrylamide. The iron oxyhydroxide and the ferrous sulfate form a cycle in the catalytic oxidation process of hypochlorous acid to accelerate the oxidative decomposition of the hypochlorous acid. 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.
Preferably, the material comprises 30 parts of iron oxyhydroxide, 30 parts of ferrous sulfate, 40 parts of calcium chloride, 20 parts of magnesium chloride, 10 parts of polyaluminium chloride and 30 parts of polyacrylamide by weight.
