Carbon release material for remedying underground water nitrate nitrogen pollution and preparation method of carbon release material

The invention discloses a carbon release material for remedying underground water nitrate nitrogen pollution and a preparation method of the carbon release material, and relates to the technical field of underground water remediation. The carbon release material comprises the following substances in parts by weight: 100 parts of water, 3 parts of a carbon source material, 1-5 parts of a framework material and 0-0.1 part of enzymes, wherein the carbon source material is wrapped by the framework material; the enzymes are used for controlling carbon release of the carbon release material. The invention provides the novel, efficient and economically feasible controlled carbon release material and the preparation method thereof, and the carbon release material can be also used as a carrier of microorganisms when used in in-situ underground water remediation of a permeable reactive barrier, meanwhile has technical advantages of being good in carbon release stability, high in pressure-resistance strength, good in bi
