Ecological environment-friendly soil remediation method

Abstract

The invention discloses an ecological environment-friendly soil remediation method, and belongs to the technical field of ecological environmental protection. The method adopts the scheme that throughthe growth of hyperaccumulator root systems, reductive iron powder in an outer spherical frame reacts with oxygen in soil, on one hand, the temperature around the hyperaccumulator root systems can bepromoted to rise by virtue of heat generated during reaction, therefore respiration of root systems is improved and thus growth of the hyperaccumulator root systems is accelerated, and on the other hand, with the help of temperature rise, a thermal phase change thin rope can be promoted to recover to a high-temperature phase state of the thermal phase change thin rope, a spherical filter screen is pulled to deform, meshes of the spherical filter screen are promoted to be enlarged, ferroferric oxide powder is promoted to penetrate through the spherical filter screen and be adsorbed on the surface of the built-in magnetic ball, and the repulsive force between the adjacent root systems is increased by virtue of the increase of the magnetism of the built-in magnetic ball, so that the root systems are promoted to diffuse outwards in the growth process, and the firmness of the plant root systems can be improved; and the treatment range of the hyperaccumulation plants on the heavy metal contaminated soil can also be widened.

Description

technical field [0001] The invention relates to the technical field of ecological environmental protection, and more specifically, relates to an ecological environmental protection soil restoration method. Background technique [0002] Ecological environment, short for "environment composed of ecological relationships", refers to various natural forces (including second nature formed under artificial intervention) that are closely related to human beings and affect human life and production activities. The sum of (matter and energy) or functions, the ecological environment refers to the general term for the quantity and quality of water resources, land resources, biological resources and climate resources that affect human survival and development, and is a composite ecosystem related to the sustainable development of society and economy. Eco-environmental problems refer to the various negative feedback effects that endanger human survival caused by the destruction and pollu...

AI Technical Summary

Problems solved by technology

[0004] In the prior art, in the process of remediating soil polluted by heavy metals, more environmentally friendly methods are usually used, so in the actual use process, hyperaccumulator plants such as centipede grass will be planted, but due to the hyperaccumulator plant itself Root growth is limited and thus also limits the reach of individual plants
