Abstract

The invention belongs to the technical field of soil remediation, and particularly relates to an aniline contaminated soil remediation material. The aniline contaminated soil remediation material is prepared from chitin, zeolite powder, green alga, humus acid, shell powder, needle mushroom residues, cobs, rice bran, tea seed shells, peat, areca catechu wood bits, palm wood bits, a complex enzyme preparation and a compound microorganism microbial agent. By the adoption of the soil remediation material, under the condition of not introducing other chemical solvents, mild enzymes and microorganism strains are adopted for treating soil, no new contamination is brought in, the acting conditions are mild, aniline is degraded or adsorbed by the strains, and the soil property condition of the soil is obviously improved.

Description

technical field [0001] The invention belongs to the technical field of soil remediation, and in particular relates to a remediation material for aniline polluted soil. Background technique [0002] Aniline is an important chemical raw material and also a toxic chemical substance. This kind of substance mainly comes from the production process of printing and dyeing, pharmaceuticals, rubber, textile, papermaking, glaze on pottery, etc., especially the wastewater discharged from printing and dyeing factories contains aniline. The concentration of such substances is higher than the discharge standard of printing and dyeing wastewater stipulated by the state. If the wastewater is discharged into the soil, it will inevitably bring serious soil pollution. [0003] Aniline is a highly toxic substance. It combines with hemoglobin to form methemoglobin, which reduces its ability to combine with oxygen and causes animal poisoning. Long-term contact with this kind of substance can also...
