Abstract

The invention discloses a microbial carrier basalt fiber material and a preparation method thereof. According to the microbial carrier basalt fiber material and the preparation method disclosed by the invention, the surfaces of basalt fibers are treated by using high-energy rays and a modifier, chemical bonds on the surfaces of the basalt fibers are damaged to form surface defects, active sites are increased, and surface energy is reduced, so that the bonding ability between the surfaces of the basalt fibers and microorganisms is enhanced, the loading capacity of the microorganisms is increased, and further the purification efficiency of a microbial supported purification material is improved.

Description

technical field [0001] The invention relates to the field of microbial fiber carrier materials, in particular to a microbial carrier basalt fiber material and a preparation method thereof. Background technique [0002] Basalt fiber is a new type of inorganic environmentally friendly green high-performance fiber material, and it is one of the four high-performance fibers that will be developed in my country in the future. The basalt rock material composed of basalt is melted at high temperature and then prepared by spinning process. Basalt continuous fiber not only has good stability, but also has various excellent properties such as electrical insulation, corrosion resistance, combustion resistance, and high temperature resistance. Moreover, the production process of basalt fiber produces less waste and less environmental pollution. It can be directly transferred to the ecological environment without any harm, so it is a veritable green and environmental protection material....
