Embodiment 1

[0023] The new material capable of separating soil pollutants is made of the following raw material proportions by weight: 1 part of strong magnetic material, 10 parts of porous charcoal, and 10 parts of clay.

[0024] The preparation process of the above-mentioned new material capable of separating soil pollutants comprises the following steps:

[0025] The first step, mixing, stir and mix the strong magnetic material, porous carbon, and clay evenly to obtain a mixture:

[0026] In the second step, granulation, the mixture is granulated by a granulator, and the granulation particle size is 1mm, and granules are obtained after granulation;

[0027] The third step is drying, drying the granules by drying or drying, and the moisture content of the granules is less than 15%;

[0028] The fourth step is high-temperature oxygen-isolated firing. The particles are placed in a kiln for oxygen-isolated firing. The firing temperature is 400°C and the firing time is 5 hours. After firin...

Abstract

The invention discloses a novel material capable of separating soil pollutants. The novel material consists of a ferromagnetic material, porous carbon and clay. The novel material has the following beneficial effects: the prepared novel material capable of separating the soil pollutants is put into polluted soil and can effectively adsorb pollutants, especially heavy metal ions and pesticide residues, in the soil; and the magnetic adsorption material has magnetic induction capacity and can be separated from soil by utilizing magnetic attraction force and recycled in a centralized manner, and pollutants in the soil are carried out and separated from the original soil along with the adsorption material, so the aim of separating and radically treating the pollutants is fulfilled.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a new material capable of separating soil pollutants and a preparation process thereof. Background technique [0002] At present, human beings face three major pollutions: air pollution, water pollution and food pollution. Food pollution mainly comes from the migration of pollutants in the soil, followed by pollution caused by farming, food processing, storage and transportation. Among them, soil pollution has seriously threatened food safety and sustainable economic development. Therefore, it is particularly important to carry out soil treatment and ecological restoration to remove pollutants in the soil. [0003] Soil pollution includes inorganic pollution, organic pollution and biological pollution, such as heavy metal pollution, pesticide residues, and harmful organic pollution. Some of them come from nature, and some come from human production and life. ...
