Method for preparing photocatalytic glass fiber for water body purification

Abstract

The invention discloses a method for preparing a photocatalytic glass fiber for water body purification. The photocatalytic glass fiber is prepared from raw materials of waste glass, pyrophyllite, quartz sand, mirabilite, calcium oxide, dibutyl phthalate, ferric nitrate and the like. According to the method, glass fiber filaments are made by melting and drawing the raw materials such as the wasteglass, the pyrophyllite and the quartz sand into filaments, a three-dimensional spatial structure of the filaments is adopted as a carrier, ferric ions and titanium dioxide are loaded on the carrier in a compounding manner, and the large specific surface area and the excellent light permeability of the glass fiber are sufficiently utilized, so that not only is a large carrying capacity achieved, but also the glass fiber is stable in physical and chemical property in water, the photocatalytic degradability of the glass fiber is greatly improved, and various types of organic pollutants in a water body can be effectively degraded; a product prepared by using the method is easy in raw material obtaining, simple in process and applicable to industrial on-scale production, the application fieldof glass fiber materials can be further widened, and very high economic and environment benefits can be obtained.

Description

technical field [0001] The invention relates to the technical field of glass fiber materials, in particular to a method for preparing photocatalytic glass fibers for water body purification. Background technique [0002] With the development of my country's industry and agriculture, the demand for water and chemical resources is gradually increasing. However, China has a large population and a relatively short supply of resources per capita. How to save water resources and reuse water resources has become a concern of people, and in the reuse of water resources, sewage treatment is the top priority. At present, the most common method of sewage treatment is to use sewage treatment agent or sewage purification agent, but the treatment effect is not stable, and the treatment process is complicated, the one-time industrial investment is large, and there are many residues. [0003] Photocatalysis is a promising water treatment technology, because it can use sunlight or ultravio...

Problems solved by technology

Due to its extremely small diameter, ranging from a few microns to more than twenty microns, which is equivalent to 1 / 20-1 / 5 of a hair, it has a very high specific surface area and has ideal stability when used as a carrier and loading capacity, but the current research on the application of glass fiber in water pollution treatment is relatively rare
