A copper-based iron-carbon microelectrolysis catalyst

Abstract

The invention relates to a copper-based iron carbon micro-electrolysis catalyst which is prepared from the following raw materials in parts by weight: 10-20 parts of industrial cupric oxide, 30-40 parts of iron trioxide, 35-42 parts of lignite, 5-40 parts of a structure auxiliary and 5-20 parts of a high-strength adhesive. A preparation method for the copper-based iron carbon micro-electrolysis catalyst comprises the following steps: conventionally mixing and kneading the raw materials in a vacuum condition, and then pressing the raw materials to form an initial copper-based iron carbon micro-electrolysis catalyst blank with a mold; and pressing for molding with the mold, drying at the temperature 150 DEG C, and calcining in a kiln with the temperature being 1100-1300 DEG C to obtain the copper-based iron carbon micro-electrolysis catalyst. The copper-based iron carbon micro-electrolysis catalyst has the advantages of good activity, large pore volume, high strength, no powder falling, no secondary pollution to water, long service life and low cost, can be efficiently used in removing of COD of all kinds of sewage, can remove the chromaticity, can improve the biodegradability, is widely applied to treatment of drinking tap water, domestic water, livestock drinking water, natural dead water, wastewater, industrial wastewater, pesticides, chemical wastewater, papermaking, printing and dyeing dull color water and polluted water containing heavy metals after iron and steel smelting.

Description

technical field [0001] The invention relates to a micro-electrolysis supported catalyst in sewage treatment, in particular to a copper-based iron-carbon micro-electrolysis catalyst. Background technique [0002] The treatment of high-concentration and difficult industrial wastewater is the top priority of every environmental protection enterprise. Many similar products are also produced on the market, most of which only have mitigating treatment, the main reason is that no suitable active components have been selected, so the selective adsorption of target materials is low, the catalyst strength is not enough, and in sewage During the treatment, the degree of falling powder is relatively large, and rust and coal ash are produced to cause secondary pollution to water. [0003] People in the industry know that sewage in industries such as chemical fertilizers, pesticides, papermaking, winemaking, and printing and dyeing is very difficult to treat. Currently, all treatment age...

Many similar products are also produced on the market, most of which only have mitigating treatment, the main reason is that no suitable active components have been selected, so the selective adsorption of target materials is low, the catalyst strength is not enough, and in sewage During the treatment, the degree of falling powder is relatively large, and rust and coal ash are produced, which will cause secondary pollution to water

[0003] People in the industry know that sewage in industries such as chemical fertilizers, pesticides, papermaking, winemaking, and printing and dyeing is very difficult to treat. Currently, all treatment agents on the market generally have low pore volume and activity, high powder falling, and water-resistance. Secondary pollution, short service life, high cost accounting, etc.

Although the country attaches great importance to it and the enterprises redouble their efforts, the iron-carbon micro-electrolysis sewage treatment agent produced still fails to meet the environmental protection requirements of sewage treatment.
