Embodiment 1

[0034] Example 1: The restoration method of using animals to treat soil heavily polluted by heavy metals, including insecticide spraying, earthworm enrichment restoration, and microbial decomposition.

[0035] In the insecticide spraying process, the insecticide is mainly prepared from 280 parts of organic fertilizer, 28 parts of microbial agent, 0.03 part of matrine and 0.02 part of Bacillus thuringiensis powder, all in parts by mass (35g / part ).

[0036] The preparation technology of described insecticide is:

[0037] A. Put the organic fertilizer on a sterile plastic film, spread it flat, cover it with a sterile plastic film for ultraviolet sterilization for 1-5 days, remove the film, put it in a cool place, and then add microbial agents (Huiminda bacteria) fertilizer), mix well and set aside;

[0038] B. Put matrine in a non-iron container, soak it in warm water at 10°C for 40 minutes, use 1-5 times the weight of the raw material, put it on a smokeless stove, and fry it ...

Embodiment 2

[0046] Example 2: The restoration method of using animals to treat soil heavily polluted by heavy metals, including insecticide spraying, earthworm enrichment restoration, and microbial decomposition.

[0047] In the insecticide spraying process, the insecticide is mainly prepared from 320 parts of organic fertilizer, 32 parts of microbial agent, 0.09 part of matrine and 0.06 part of Bacillus thuringiensis powder, all in parts by mass (45g / part ).

[0048] The preparation technology of described insecticide is:

[0049] A. Put the organic fertilizer on a sterile plastic film, spread it flat, cover it with a sterile plastic film for ultraviolet sterilization for 1-5 days, remove the film, put it in a cool place, and then add microbial agents (Huiminda bacteria) fertilizer), mix well and set aside;

[0050] B. Put matrine in a non-iron container, soak it in warm water at 20°C for 20 minutes, use 1-5 times the weight of the raw material, put it on a smokeless stove, and fry it ...

Embodiment 3

[0058] Example 3: The restoration method of using animals to treat soil heavily polluted by heavy metals, including insecticide spraying, earthworm enrichment restoration, and microbial decomposition.

[0059] In the insecticide spraying process, the insecticide is mainly prepared from 300 parts of organic fertilizer, 30 parts of microbial agent, 0.06 part of matrine and 0.04 part of Bacillus thuringiensis powder, all in parts by mass (55g / part ).

[0060] The preparation technology of described insecticide is:

[0061] A. Put the organic fertilizer on a sterile plastic film, spread it flat, cover it with a sterile plastic film for ultraviolet sterilization for 1-5 days, remove the film, put it in a cool place, and then add microbial agents (Huiminda bacteria) fertilizer), mix well and set aside;

[0062] B. Put matrine in a non-iron container, soak it in warm water at 20°C for 20 minutes, use 1-5 times the weight of the raw material, put it on a smokeless stove, and fry it ...

Abstract

The invention provides a method for repairing serious heavy metal contaminated soil. The method mainly comprises three processes of spraying an insecticide, repairing earthworm enrichment, and carrying out microbial decomposition. According to the method, a complete repair cycle is completed by spraying the insecticide, repairing earthworm enrichment, and carrying out microbial decomposition. One repair cycle lasts for two months, and three repair cycles, from the March in the Gregorian calendar to the September in the Gregorian calendar, are required. The innovation point of the method is that heavy metal removal is carried out by utilizing animals to avoid secondary contamination risk, and earthworms belong to animals which grow quickly, so that the whole treatment and repair period is relatively short; the special insecticide is used, and is prepared by combining an organic fertilizer with vegetable drugs and chemicals with insecticidal effect, so that the soil fertilizer efficiency can be improved, and pests in the soil and on the ground further can be killed; the process of carrying out microbial decomposition is added, so that microorganisms can be effectively decomposed; and moreover, dung beetles are utilized for decomposition.

Description

[0001] Divisional application, original application number 2014105572793, application date 2014.10.21, titled Remediation method for treating heavy metal-contaminated soil by using animals. technical field [0002] The invention relates to a soil remediation method, in particular to a method for remediating soil heavily polluted by heavy metals by using animals, and belongs to the field of soil remediation methods. Background technique [0003] Soil heavy metal pollution refers to the phenomenon that human activities add heavy metals to the soil, causing the heavy metals in the soil to be significantly higher than the original content, and causing the deterioration of the ecological environment. Soil is one of the main natural resources that human beings rely on for survival, and it is also a traditional Chinese medicine component of the human ecological environment. In the process of industrialization, urban pollution has intensified, and the types and quantities of agricul...
