Abstract
An iron-carbon composite material, a preparation method therefor, and an application thereof related to microbial technology applications. The method includes the following steps: a cross-linking and curing step: carrying out cross-linking and curing to iron powder and biological activated carbon by using an alkaline earth metal salt and a cross-linking agent; and a mineralization treatment step: soaking the cross-linked and cured iron-carbon composite material in a mineralization bacteria solution for 5-15 min, and carrying out drying to obtain an iron-carbon composite material. Mineralization bacteria utilize alkaline earth metal ions to form an alkaline earth metal carbonate structure on the surface of the iron-carbon composite material, thereby greatly improving the strength of the iron-carbon composite material; in addition, the soaking time in the mineralization bacteria solution is controlled to prevent the formation of a compact metal carbonate film from affecting the functioning of effective components in the iron-carbon composite material.
