Embodiment Construction

[0028] The following (Fe 0.99 Mo 0.01 ) 78 Si 9 B 13 Amorphous alloy strips are used as an example to illustrate the implementation of the method, and by combining with crystallized (Fe 0.99 Mo 0.01 ) 78 Si 9 B 13 The comparison of the strips is used to illustrate the decolorization effect of the material, and the feasibility of reusing the amorphous strips for decolorization is illustrated through related diagrams.

[0029] 1. According to the technical scheme mentioned above, for the atomic percentage composition of the alloy (Fe 0.99 Mo 0.01 ) 78 Si 9 B 13 As far as it is concerned, it is a very common component with a strong ability to form amorphous strips. The production technology is relatively mature and has been industrialized. Wherein the atomic percentage of the iron element is about 78%, which meets the appropriate composition range required in the technical proposal.

[0030] 2. Using Fe, Mo, Si, Fe 80 B 20 (wt.%) for smelting. Calculate the requi...

Abstract

The invention relates to a ferrum (Fe)-based amorphous alloy material, in particular to a Fe-based amorphous alloy strip for treating printing and dyeing wastewater and a preparation method thereof. According to the conventional literatures and technical data, an alloy component with Fe-based amorphous alloy strip forming capacity is selected; and general requirements show that the selected alloy component comprises more than 50 percent of Fe atoms, preferably 60 to 85 percent, so the reduction decoloring capacity of the Fe atoms is exerted. The amorphous alloy strip is obtained by adding a small amount of other elements and performing rapid solidification by using melt spinning equipment. The decrystallization of zero-valent Fe is realized by preprocessing technology; the decoloring capacity of the Fe atoms is kept; the rusting consumption of the Fe in the wastewater treatment process is effectively reduced; the strip is repeatedly and persistently utilized on the premise of guaranteeing the decoloring rate; the technical defects and the application defects in the conventional method for treating the printing and dyeing wastewater by using reducing Fe powder or waste cast Fe scraps are overcome; and the Fe-based amorphous alloy strip relates to the field of potential application of decrystallization technology in the industrial field, and has an extremely high application prospect.

Description

Technical field [0001] The invention relates to an Fe-based amorphous alloy material, in particular to an Fe-based amorphous alloy strip used for the treatment of printing and dyeing wastewater and a preparation method thereof. The material has good properties for the treatment of printing and dyeing wastewater, especially azo dye printing and dyeing wastewater Effect. Background technique [0002] At present, printing and dyeing wastewater treatment technologies mainly include physical adsorption method, chemical flocculation method, membrane separation method, chemical oxidation method, biodegradation method, etc. These different existing treatment technologies have their own advantages, disadvantages and applicability. For example, activated carbon adsorption has a good treatment effect on printing and dyeing wastewater, but due to its high price and difficult regeneration, it is generally only used for low-concentration wastewater or advanced treatment; while inorganic f...
