A device for treating petroleum-contaminated soil with microorganisms and plants

Abstract

The invention discloses a device for treating petroleum-contaminated soil by enabling microorganisms to match with plants. The device comprises a laying board, a motor, a planting board, a plow-shareand a culture device, wherein one end of the laying board is equipped with a plate-shaped structure of the motor; one side, away from the motor, of the laying board is equipped with an inclined surface; the plow-share is fixedly mounted below the inclined surface; a laying board slot for allowing the planting board to mount is formed inside the laying board; the laying board slot is formed in an inclined mode; the tail end of the laying board slot faces towards the motor and extends to the outside of the laying board; the position, close to the plow-share, of the bottom end of the laying boardis symmetrically equipped with two groups of driven wheels; the position, close to the motor, of the bottom end of the laying board is symmetrically equipped with two groups of drive wheels; and thedrive wheels are in transmission fit to the driven wheels through second transmission belts. The device for treating petroleum-contaminated soil by enabling microorganisms to match with plants disclosed by the invention is reasonable in structure, is easily used, effectively treats and restores petroleum-contaminated soil, and has a relatively high practical value.

Description

technical field [0001] The invention belongs to the technical field of soil pollution treatment, and in particular relates to a device for treating petroleum-contaminated soil by using microorganisms and plants. Background technique [0002] With the rapid development of the global industrialization process, the demand for petroleum products is also increasing. In the process of mining, production and transportation of petroleum and petroleum products, it is inevitable that a certain amount of petroleum and products will enter the soil, causing pollution. Petroleum is highly adhesive, which will affect some physical and chemical properties of the soil, and will also hinder the respiration of plant roots and the absorption of nutrients, seriously endangering the growth of plants. [0003] Most of the existing soil remediation technologies are manually operated and mechanically repaired, which requires long-term conditioning and consumes manpower and material resources. There...

Petroleum is highly adhesive, which will affect some physical and chemical properties of the soil, and will also hinder the respiration of plant roots and the absorption of nutrients, seriously endangering the growth of plants.

[0003] Most of the existing soil remediation technologies are manually operated and mechanically repaired, which requires long-term conditioning and consumes manpower and material resources. Therefore, the method of soil treatment by microorganisms is gradually developed. Survival, affect the treatment effect
