Activating agent and activating method of manganese dioxide solid slag

Abstract

The invention discloses an activating agent and a manganese dioxide solid slag activating method, and belongs to the technical field of manganese dioxide solid slag treatment. The activating agent comprises the following components in parts by weight: 60-95 parts of a component A and 5-40 parts of a component B, wherein the component A is trimethyl carboxymethyl ammonium; and the component B is an alkoxy phenol compound. The activation method of the manganese dioxide solid slag comprises the following steps: filtering out the manganese dioxide solid slag, and washing to obtain a manganese dioxide coarse material; then adding a component A into a manganese dioxide coarse material in parts by weight, uniformly mixing the components, and activating the mixture at the temperature of 40-90 DEG C for 10-60 minutes; then adding the component B in parts by weight, uniformly mixing the components, and activating the mixture at the temperature of 40-90 DEG C for 10-60 minutes; and after activation, filtering and drying the material to obtain the active manganese dioxide. The activating agent and the activating method effectively improve the oxidation capacity of manganese dioxide, and are low in cost, simple, convenient and feasible in method and suitable for actual production.

Description

technical field [0001] An activator and an activation method for manganese dioxide solid slag belong to the technical field of manganese dioxide solid slag treatment. Background technique [0002] Manganese dioxide is a relatively common industrial production waste residue, which has a high value for further development. Chemical manganese dioxide has many excellent properties and can be used in sewage treatment, high-performance batteries, catalysts, oxidants, electronics, and is expected to become a good heat-sensitive material. With the rapid development of the chemical industry, more and more types and quantities of organic substances are used, and the organic wastewater generated in the production process is becoming more and more difficult to treat. Therefore, an economical and efficient method for treating organic wastewater is needed, and activated manganese dioxide has strong oxidative degradation ability, and has excellent performance in organic wastewater treatme...

AI Technical Summary

Problems solved by technology

[0003] Most of the prior art disclosures are high-content manganese dioxide catalysts or nanocomposites containing manganese dioxide for wastewater treatment. For example, Chinese patent CN201010230006.X uses the reaction of potassium permanganate and manganese sulfate, which is more special Manganese dioxide nanomaterials are obtained by the hydrothermal treatment method. This method not only has a high cost of raw material sources, but also adopts the hydrothermal method for treatment, and must use a hydrothermal reactor, which requires high reaction equipment. In addition, when the method treats wastewater Ozonation treatment with high cost is also adopted, which is not conducive to large-scale industrial application

[0004] Patent CN102275994 added dilute sulfuric acid and potassium permanganate for oxidation and activation when extracting manganese dioxide, which increased the cost of raw materials, and the preparation method required heating, drying, and grinding. High, relatively low commercial benefit, difficult to industrialized production and limited application and promotion

[0005] The manganese dioxide activation treatment invented by patent CN108862541.A needs to be washed with tap water, industrial alcohol, and 50% nitric acid in sequence, and heat treatment is required in the subsequent treatment of organic wastewater, which is not conducive to large-scale industrial application
