Abstract

The invention discloses a high-density aquaculture sewage purification material and a viscose-based activated carbon fiber loaded with the purification material. The high-density aquaculture sewage purification material is prepared by the following method: (1) soaking bentonite and sepiolite in a concentrated acid to obtain a bentonite-sepiolite mixture; (2) mixing grease with melamine, trehaloseand a surfactant to obtain a grease mixture; (3) adding the bentonite-sepiolite mixture and the grease mixture into an organic solvent to obtain a bentonite-sepiolite-grease mixture; and (4) calciningthe bentonite-sepiolite-grease mixture to obtain the high-density aquaculture sewage purification material. The sewage purification material has excellent purification capability on high-density aquaculture sewage. Particularly, the invention provides the viscose-based activated carbon fiber loaded with the high-density aquaculture sewage purification material. The high-density aquaculture sewagepurification material has higher purification capacity for high-density aquaculture sewage.

Description

technical field [0001] The invention relates to the technical field of preparation of water treatment materials, in particular to a high-density aquaculture sewage purification material and viscose-based activated carbon fibers loaded with the purification material. Background technique [0002] With the development of high-density aquaculture technology, high-density aquaculture technology occupies an important position in the aquaculture industry. It is common to place tools such as net cages and fences in lakes, reservoirs, and fish ponds for high-density aquaculture. However, the waters of lakes, reservoirs, and fish ponds are relatively closed, and the self-purification capacity of water bodies is often less than the pollution ability of high-density aquaculture. Therefore, high-density aquaculture has caused environmental damage to lakes, reservoirs, and fish ponds; Sustainable development of density aquaculture. Therefore, it is of great significance to develop a wa...
