Embodiment 1

[0029] Example 1 The method for comprehensively utilizing biochemical resources to restore heavy metal-contaminated soil includes three processes: insecticide spraying, earthworm enrichment and restoration, and microbial decomposition. The insecticide is prepared from the following materials, all in parts by mass: 280kg of organic fertilizer, 28kg of microbial agent, 0.05kg of pyrethrum, 0.03kg of deervine and 0.02kg of Bacillus thuringiensis powder.

[0030] The preparation technology of described insecticide is:

[0031] ① Put the organic fertilizer on a sterile plastic film, spread it flat, cover it with a sterile plastic film for ultraviolet sterilization for 1 day, remove the film, put it in a cool place, add microbial agents and mix well for later use;

[0032] ②Put pyrethrum and deer vine in a non-iron container, soak in warm water at a temperature of 10-20°C for 30 minutes. Boil for 30 minutes, let stand for 5 hours, and take the supernatant for later use;

Embodiment 2

[0039] Example 2 The method for comprehensively utilizing biochemical resources to restore heavy metal-contaminated soil includes three processes: insecticide spraying, earthworm enrichment and restoration, and microbial decomposition. The insecticide is prepared from the following materials, all in parts by mass: 320kg of organic fertilizer, 32kg of microbial agent, 0.1kg of pyrethrum, 0.09kg of deervine and 0.06kg of Bacillus thuringiensis powder.

[0040] The preparation technology of described insecticide is:

[0041] ① Put the organic fertilizer on a sterile plastic film, spread it flat, cover it with a sterile plastic film for ultraviolet sterilization for 5 days, remove the film, put it in a cool place, add microbial agents and mix well for later use;

[0042] ②Put pyrethrum and deer vine in a non-iron container, soak in warm water at a temperature of 10-20°C for 30 minutes, the water consumption is 5 times the weight of the raw materials, put it on a smokeless stove, s...

Embodiment 3

[0050] Example 3 The method for comprehensively utilizing biochemical resources to restore heavy metal-contaminated soil includes three processes: insecticide spraying, earthworm enrichment and restoration, and microbial decomposition. The insecticide is prepared from the following materials, all in parts by mass: 290kg of organic fertilizer, 29kg of microbial agent, 0.06kg of pyrethrum, 0.05kg of deervine and 0.03kg of Bacillus thuringiensis powder.

[0051] The preparation technology of described insecticide is:

[0052] ① Put the organic fertilizer on a sterile plastic film, spread it flat, cover it with a sterile plastic film for ultraviolet sterilization for 2 days, remove the film, put it in a cool place, add microbial agents and mix well for later use;

[0053] ②Put pyrethrum and deer vine in a non-iron container, soak in warm boiling water at a temperature of 10-20°C for 30 minutes, the water consumption is 3.5 times the weight of the raw materials, put it on a smokele...

Abstract

The invention discloses a method for remediation of heavy metal contaminated soil. The method comprises three processes of insecticide spraying, earthworm enriching remediation and microbial decomposition. Insecticide in the insecticide spraying process is prepared from, by mass, 280-320 parts of organic fertilizer, 28-32 parts of a microbial agent, 0.05-0.1 part of pyrethrum, 0.03-0.09 part of derris and 0.02-0.06 part of agritol powder. According to the method for remediation of the heavy metal contaminated soil, the fertilizer efficiency of the soil can be improved, and injurious insects in the soil and on the earth surface can be killed; and the microbial decomposition process is further added, so that the effect is remarkable, and operation is easy.

Description

technical field [0001] The invention discloses a soil remediation method, in particular to a method for comprehensively utilizing biochemical resources to repair heavy metal-contaminated soil, and belongs to the field of soil remediation methods. Background technique [0002] Soil heavy metal pollution refers to the phenomenon that due to the addition of metals to the soil due to human activities, the heavy metals in the soil are significantly higher than the original content, and the quality of the ecological environment is deteriorated. Heavy metals in polluted soil mainly include mercury (Hg), cadmium (Cd), lead (Pb), chromium (Cr) and metalloid arsenic (As) and other elements with significant biological toxicity, as well as zinc (Zn) and copper with certain toxicity. (Cu), nickel (Ni) and other elements. Mainly come from pesticides, wastewater, sludge and atmospheric deposition, etc. For example, mercury mainly comes from mercury-containing wastewater, cadmium and lead ...
