Embodiment Construction

[0032] Industrial waste particles such as steel slag, coal slag, and fly ash not only have a huge specific surface area, but also contain a large amount of metal oxides such as Ca, Al, and Fe, and have strong adsorption and reaction capabilities for phosphorus in water. Natural zeolite is a kind of porous aluminosilicate mineral with frame structure, which has abundant reserves. Its internal complex lattice structure determines its unique physical and chemical characteristics. It is found that zeolite has good adsorption performance, ion exchange performance and catalytic performance. Functional fiber adsorption materials such as cellulose acetate, PVA, polyacrylonitrile, and chitosan have the advantages of wide source, renewable, high output, low price, etc., and the adsorption rate is fast, which is suitable for rapid treatment of high-concentration wastewater. Basalt fiber is a continuous fiber formed by drawing natural basalt as raw material after melting at a high tempera...

Abstract

The invention provides an industrial waste residue based composite fiber dephosphorization material and a preparation method thereof. The material comprises coal ash, steel slag, zeolite, basalt fibers and a forming material, wherein the mass ratio of each material in the total mass of the composite fiber material is shown in the description. With the adoption of the composite fiber dephosphorization material, the phosphorus concentration in drained sewage (wastewater) reaches the national standard; the water enriching condition is reduced, so that the ecological environment of an area is improved. The material is developed, produced, applied and finally treated; the industrial waste residue is recycled; the added value of the waste residue utilization is increased; the phosphorus resourcerecovering cost is decreased; the environment is protected and improved; the waste residues are recycled; the social benefit and the economic benefit are high.

Description

technical field [0001] The invention relates to an industrial waste slag-based composite fiber dephosphorization material used for sewage (waste) water treatment, and belongs to the technical field of water pollution prevention and control. Background technique [0002] Phosphorus is the main factor leading to eutrophication of water bodies. At the same time, phosphorus is also an indispensable nutrient element for life, and it is a resource that is difficult to regenerate and is increasingly exhausted. [0003] At present, the removal methods of phosphorus in sewage mainly include biological and chemical methods. The biological phosphorus removal process is complicated, and the effluent stability is poor; the chemical phosphorus removal is effective, but the phosphorus removal (pharmaceutical) materials used are mostly lime, aluminum salts, iron salts, ferrous salts, and magnesium salts. Due to the high cost of phosphorus removal agents and the large amount of sludge, thi...
