Problems solved by technology
[0003] The remediation technologies for heavy metal-contaminated soil mainly include physical remediation methods, chemical leaching, phytoremediation, etc. Among them, the chemical leaching remediation method is the most widely used. The advantages of stable treatment effect and thorough restoration, but the current chemical leaching system occupies a very large area, especially the transmission line of the soil during leaching is long, and the leaching is not sufficient, which affects the restoration effect of the soil

The invention discloses a cyclic chemical leaching soil repair system and a repair method thereof, comprising a rotary transmission device, a leaching assembly, a rotary leaching container, and a guide assembly. The rotary transmission device is an annular transmission structure, and the soil enters The feeding device is set corresponding to the soil feed end, and the soil discharge device is set corresponding to the soil discharge end, and the guide assembly blocks or connects the feeding channel between the soil discharge end and the soil discharge device; The washing containers are arranged at intervals along the rotation direction of the rotary conveyor, and the rotary conveyor passes through the inner cavity of the rotary rinse container along the rotation axis of the rotary rinse container, and the inner cavity of the rotary rinse container is provided with a rinse Assemblies, the rinsing assembly sprays the rinsing repair agent on the conveying surface of the rotary conveying device passing through the inner chamber of the rotating rinsing container, which can reduce the overall footprint of the system and can greatly improve the sufficiency of soil remediation .
Description
technical field [0001] The invention belongs to the field of soil remediation, and in particular relates to a soil remediation system and a remediation method for cyclic chemical leaching. Background technique [0002] Soil is an important part of the natural environment and the material basis for human survival. In recent years, various human activities have had an increasing impact on the soil environment, and soil heavy metal pollution has become increasingly serious. Soil heavy metal pollution comes from a wide range of sources, mainly from human production and living activities, including mining, smelting, metal processing, chemical industry, waste battery treatment, electronics, tanning and dyestuffs and other industrial wastes, vehicle exhaust emissions, pesticides and fertilizers. Wait. [0003] The remediation technologies for heavy metal-contaminated soil mainly include physical remediation methods, chemical leaching, phytoremediation, etc. Among them, the chemic...
