Abstract

The invention belongs to the technical field of soil remediation and specifically relates to a phenol contaminated soil remediation material. The phenol contaminated soil remediation material comprises the following ingredients: chitin, zeolite powder, green alga, humic acid, shell powder, golden mushroom bran, corncob, rice bran, tea seed shell, peat ash, sawdust of betelnut trees, sawdust of palm trees, a compound enzyme preparation and a compound microbial agent. By the use of the soil remediation material, under the condition of not introducing other chemical solvents, mild enzymes and microbial strains are adopted for soil treatment without introducing new pollutants. The reaction condition is mild, and the strains degrade or adsorb phenols and also have obvious effects of improving soil conditions.

Description

technical field [0001] The invention belongs to the technical field of soil remediation, and in particular relates to a phenolic polluted soil remediation material. Background technique [0002] Phenol is a common organic pollutant in the environment, mainly from industrial wastewater such as oil refining, papermaking, and chemical industry. Phenol is highly toxic, and my country and some other countries list it as a priority pollutant. If a certain amount of phenol is ingested in the human body, poisoning symptoms will appear, such as dizziness, anemia and various nervous system symptoms. [0003] Phenol exists in the exhaust gas of oil refining, coking, petrochemical, chemical and chemical industries, etc. There is also a small amount of phenol in the exhaust gas from automobiles and cigarette smoke, and there is also a certain amount of phenol in the air of hospitals. [0004] Adhesives used in construction, decoration engineering, furniture production, daily office and...
