Abstract

The invention discloses a soil leaching remediation tower. The tower comprises a tower cover, a cylindrical tower body and a conical tower bottom, the center of the tower cover is provided with a water inlet pipe for guiding in a leacheate; a leaching rotary barrel for leaching soil is arranged in the tower body; the leaching rotary barrel consists of a barrel body, a barrel bottom plate and a leachate diffusion pipe in the center of the barrel; the barrel body consists of a filter cylinder and an outer cylinder; a drainage interlayer is arranged between the filter cylinder and the outer cylinder; a circle of drain holes are formed in the side wall of the bottom of the outer cylinder, an annular water collecting groove fixed to the inner wall of the tower body is formed outside the drain holes and connected with a water outlet pipe leading to the outside of the tower, four round discharge ports are evenly distributed in the barrel bottom plate in the circumferential direction, an electric valve is arranged on each discharge port, and a rotating shaft is arranged in the center of the bottom of the barrel bottom plate. A leacheate enters from the leacheate diffusion pipe, leaches soil from top to bottom and from inside to outside, and leaches heavy-metal soil uniformly and fully under the action of centrifugal force of the leaching rotary barrel, and the leaching efficiency is high.

Description

technical field [0001] The invention relates to contaminated soil remediation equipment, in particular to a soil rinsing and remediation tower. Background technique [0002] At present, the area of ​​cultivated land polluted by heavy metals such as cadmium, arsenic, chromium, and lead in my country is nearly 20 million hectares. With the acceleration of urbanization and industrialization, more and more land is polluted by heavy metals. Heavy metal legacy sites urgently need treatment. Soil heavy metal pollution is concealed, lagging and long-term. Heavy metals enter plants through the root system, inhibit plant growth, and indirectly threaten human life and health. At the same time, heavy metal pollutants will also migrate and be exposed to groundwater. and the atmosphere, destroying the ecological environment. [0003] Soil chemical leaching restoration technology is widely used due to its high efficiency and fast speed. Commonly used ectopic chemical leaching devices most...
