Soil heavy mental purification method based on ornamental plants and microorganisms

Abstract

The invention discloses a soil heavy mental purification method based on ornamental plants and microorganisms. The soil heavy mental purification method includes the specific steps of 1, detecting thecontent of heavy metals in soil; 2, crushing polluted soil before treatment, scattering a microbial mixture and activated carbon powder into the soil evenly with turning over, and earthing up the surface of the soil; 3, planting the ornamental plants in the soil and adding a mixed microbial culture medium into trenches; 4, turning over the soil in the trenches secondarily and adding excrement ofanimals; 5, subjecting the content of the heavy metals to process detection; 6, detecting the polluted soil after growth of the ornamental plants, stopping remedying when detection results show that the soil is safe, or otherwise continuing remedying. The soil heavy mental purification method based on the ornamental plants and the microorganisms has the advantage that the content of the heavy metals in the soil can be lowered effectively under the synergistic effect of the ornamental plants and the microorganisms, so that heavy metal pollution of the soil is reduced.

Description

technical field [0001] The invention relates to the field of soil purification, in particular to a soil heavy metal purification method based on ornamental plants and microorganisms. Background technique [0002] The rapid development of modern society brings people a lot of harm while bringing people an ever-changing material life, many of which are caused by people's excessive intervention in nature. Soil is the foundation of plant survival and the foundation of human survival. Since people engaged in agricultural production, people have been constantly asking for land. Especially since the development of modern agriculture, people have used excessive chemical fertilizers and pesticides, which has damaged the soil structure. Destruction, loss of activity, agglomeration, mineralization and cracking, damage to the continuity of land cultivation, resulting in excessive accumulation of toxic heavy metals in the soil, heavy metals themselves are difficult to degrade, heavy meta...

Problems solved by technology

Soil mulching and chemical cleaning are not easy to implement because they are costly and can lead to secondary pollution and loss of soil quality

Low-cost, safe and reliable phytoremediation technology has attracted much attention in recent years in the treatment of heavy metal pollution in soil, but this method absorbs less heavy metals, which brings inconvenience to people's use
