Abstract

The invention provides a microbial soil improving agent for restoring petroleum polluted soil. A product is prepared from a degradation bacterial agent, an additive and a biosurfactant, wherein the degradation bacterial agent is prepared from pseudomonas, bacillus, Acinetobacter, microzyme, phosphate-solubilizing bacteria, azotobacterial, nitrobacteria and photosynthetic bacteria; the additive isprepared from the following ingredients in parts by weight: 20 to 35 parts of wormcast, 80 to 120 parts of bentonite, 1 to 10 parts of chitosan, 10 to 20 parts of kaolin, 5 to 9 parts of borax, 25 to35 parts of crop stalks, 10 to 15 parts of rice hull powder, 10 to 15 parts of dry seaweed, 1 to 5 parts of organic acid, 5 to 10 parts of vermiculite, 10 to 20 parts of shell powder and 20 to 25 parts of compound amino acid. The microbial soil improving agent for restoring petroleum polluted soil has the advantages that the soil fertility is improved; the petroleum in the soil can be degraded; the goal of governing the petroleum polluted soil is achieved.

Description

technical field [0001] The invention belongs to the technical field of soil improvement, and in particular relates to a microbial soil improver for repairing oil-contaminated soil and a preparation method thereof. Background technique [0002] During the extraction, transportation, storage, refining and use of crude oil, a large amount of crude oil and its derivatives inevitably enter the environment, causing serious pollution to the soil. The chemical composition of crude oil is complex, including various toxic substances such as alkanes, cycloalkanes, and aromatics. Some of these aromatic compounds have potential or proven carcinogenic, mutagenic, and mutagenic effects, and can pass through the food chain in animals, plants, and The accumulation in the human body poses a huge threat to the ecological environment and human health. [0003] Bioremediation technology is an emerging technology developed in recent years to clean the environment. It uses the life activities of ...
