Embodiment approach

[0047] According to a particularly preferred embodiment of the present invention, the adsorption material is prepared according to the following method:

[0048] Preparation of impregnating solution: prepare an aqueous solution ( mn 2+ , Sn 2+ 、Ni 2+ , Sb 3+ 、Co 2 + The mass ratio is 3-6:3-6:2-3:2-3:1, wherein the concentration of non-ionic polyacrylamide is 25-30mg / L, metal cation (Mn 2+ , Sn 2+ 、Ni 2+ , Sb 3+ 、Co 2+ ) total concentration of 25-30mg / L.

[0049] Adsorption material preparation: The alumina honeycomb ceramics with a diameter of 2-3cm and a height of 1-2cm are impregnated in the above-mentioned impregnation solution by excessive impregnation. The volume ratio of alumina honeycomb ceramics to the impregnation solution is about 1: 8-12. Immersion time 1-3h, temperature 25-35 ℃. Hang the impregnated alumina honeycomb ceramics to dry in the air to remove excess solution, then put it into an oven, and dry it at 80-85° C. for 20-24 hours. Obtain adsorben...

Abstract

The invention relates to the technical field of adsorption separation, and discloses an adsorption material, which comprises an alumina matrix, and polyacrylamide and metal cations loaded on the alumina matrix. The adsorption material provided by the invention is high in adsorption efficiency, large in unit adsorption capacity and long in continuous service life, and has the advantages that the preparation method is simple, the adsorption material can be regenerated and repeatedly used for multiple times, and the performance is still stable after the adsorption material is repeatedly used for multiple times. The method is especially suitable for adsorption treatment of dye wastewater, the treated wastewater can reach the discharge or biochemical treatment standard, and the method is suitable for industrial large-scale production and application.

Description

technical field [0001] The invention relates to the technical field of adsorption separation, in particular to an adsorption material and a preparation method thereof, a treatment method of dye wastewater and their application. Background technique [0002] With the rapid development of the textile industry, the types and quantities of dye wastewater discharged into the water body are increasing, and it has become one of the key pollution sources of the water environment. Dye wastewater has the characteristics of high water chroma, complex organic components, strong acidity and alkalinity, high salt content, and low degree of microbial degradation. It has always been a major problem in the treatment of worker wastewater. For example, methyl red is an anionic organic dye commonly used in industry, and is widely used in fields such as textiles, printing, printing and dyeing, and plastics. Methyl red is an anionic azo dye, and the wastewater containing azo dye accounts for mor...
