A kind of composite basalt fiber carrier material and preparation method thereof

Abstract

The invention discloses a composite basalt fiber carrier material and a preparation method thereof. The carrier material comprises the following components in parts by weight: 95.0-99.9 parts of basalt and 0.1-5.0 parts of phosphate. Phosphorus is introduced in basalt fibers to increase active sites on the surfaces of the basalt fibers and reduce surface energy, so that microorganisms can be easily loaded on the basalt fibers, an adhesive force is large, the loading amount of the microorganisms is large, the purifying efficiency of a microorganism purifying material which takes the basalt fibers as a carrier is improved, and popularization and application of the basalt fiber material in water purification are promoted.

Description

technical field [0001] The invention relates to the field of microbial fiber carrier materials, in particular to a composite basalt fiber carrier 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....

Problems solved by technology

[0004] The purpose of the present invention is to overcome the shortcomings of low microbial load and weak adhesion caused by the direct use of basalt fiber as a microbial water purification material carrier due to the high surface energy of basalt fiber and poor chemical bonding ability with microorganisms, and to provide a composite basalt fiber Carrier material and preparation method thereof; the present invention increases active sites on the surface of basalt fiber by introducing phosphorus elements with multi-valence, active performance and easy bonding with microorganisms into basalt fibers, reduces surface energy, and makes microorganisms easier to load On the basalt fiber, the adhesion is stronger and the microbial load is larger, thereby improving the purification efficiency of the microbial purification material with basalt fiber as the carrier, and promoting the popularization and application of basalt fiber materials in water purification
