Abstract

The invention discloses a composite basalt fiber purification material and a preparation method thereof. The purification material is prepared from a composite basalt fiber carrier and water purification microorganisms loaded on the carrier, and the composite basalt fibers are prepared from 95.0-99.9 parts of basalt and 0.1-5.0 parts of phosphate. According to the composite basalt fiber purification material and the preparation method thereof, the composite basalt fibers which are subjected to composite modification treatment and have a large quantity of surface active sites, low surface energy and higher bonding capability with microorganisms serve as the carrier, then the microorganisms are loaded on the composite basalt fibers, and thus the water purification material is obtained; the purification material is large in microorganism loading capacity and high in water purifying efficiency, and application and popularization of the basalt fiber water purification material are promoted.

Description

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