Surface soil shallow layer repairing device and land resource planting and recycling equipment

Abstract

The invention relates to the technical field of polluted soil treatment, in particular to an earth surface soil shallow layer repairing device and land resource planting and recycling equipment. According to the technical scheme, the device comprises a bearing plate trailer and a square containing window formed in the plate trailer, a U-shaped supporting frame fixed to the bearing plate trailer is arranged on the upper side of the square containing window, an L-shaped supporting plate is fixed to the upper side of the U-shaped supporting frame, and a motor is fixed to the upper side of the L-shaped supporting plate; and an output shaft of the motor penetrates through the top of the L-shaped supporting plate and is fixedly connected with a linkage edge rod, a matching screw column connected with the linkage edge rod in a sleeving mode is in threaded connection with the upper portion of the U-shaped supporting frame, a spiral drilling rod located on the inner side of the square containing window is fixed to the lower end of the matching screw column, and a collecting hopper is jointly fixed to the upper side of the bearing plate trailer through a pair of fixing columns. According to the method, a biological treatment technology and a chemical treatment technology are integrated, multiple treatment methods are synchronously carried out, existing comprehensive treatment steps are simplified, the construction efficiency is greatly improved, and application and popularization are facilitated.

Description

technical field [0001] The invention relates to the technical field of contaminated soil treatment, in particular to a surface soil shallow repair device and land resource planting reuse equipment. Background technique [0002] Soil pollutants can be roughly divided into two categories: inorganic pollutants and organic pollutants. Inorganic pollutants mainly include acids, alkalis, heavy metals, salts, compounds of radioactive elements cesium and strontium, compounds containing arsenic, selenium and fluorine, etc. Soil heavy metal pollution has the characteristics of poor mobility of pollutants in soil, long residence time, and inability to be degraded by microorganisms. It can eventually affect human health through water, plants and other media, so it is very important for the treatment of polluted soil. [0003] The existing treatment methods are generally constructed separately and carried out in batches. In the treatment process, the methods usually used include: physic...

Problems solved by technology

[0003] The existing treatment methods are generally constructed separately and carried out in batches. In the treatment process, the methods usually used include: physical restoration, using electric tillage or electric current to directly affect the metal ion composition in the soil, and then achieve the restoration effect. purpose, but the repair method requires a lot of power consumption, and is suitable for soil properties with high requirements; chemical repair methods, using chemical modifiers to neutralize the soil, to reduce the content of heavy metals; biological methods, using biological methods , by adding microorganisms and planting crops that can enrich metal ions to achieve soil restoration, microorganisms can also improve the adsorption capacity of plant roots to metal ions, and improve the governance effect; there are still many governance defects in a single restoration method, in order to improve governance In order to meet the needs of the environment, a method of combined governance is proposed, but in the current stage of governance methods, there is a lack of equipment that can realize combined and synchronous governance capabilities to meet governance needs
