Embodiment 1

[0030] Example 1 Comprehensive use of biochemical resources to repair heavy metal contaminated soil, including pesticide spraying, earthworm enrichment and repair, and microbial decomposition. The insecticide is prepared from the following materials, all in parts by mass: 280 kg of organic fertilizer, 28 kg of microbial inoculants, 0.05 kg of pyrethrum, 0.03 kg of fish vines and 0.02 kg of Bacillus thuringiensis powder.

[0031] The preparation process of the insecticide is:

[0032] ①Put the organic fertilizer on a sterile plastic film, flatten it, and cover it with a sterile plastic film for UV sterilization for 1 day, lift off the film, and put it in a cool place, add microbial agents and mix well for later use;

[0033] ②Put the pyrethrum and roe in a non-ferrous container, soak them in warm water at a temperature of 10-20℃ for 30 minutes. The water consumption is 3 times the weight of the raw materials. Place them on a smokeless stove and seal the small fire. Decoction for 30 ...

Embodiment 2

[0040] Example 2 Comprehensive use of biochemical resources to repair heavy metal contaminated soil, including pesticide spraying, earthworm enrichment and repair, and microbial decomposition. The insecticide is prepared from the following materials, all in parts by mass: 320 kg of organic fertilizer, 32 kg of microbial inoculants, 0.1 kg of pyrethrum, 0.09 kg of fish vines and 0.06 kg of Bacillus thuringiensis powder.

[0041] The preparation process of the insecticide is:

[0042] ①Put the organic fertilizer on a sterile plastic film, spread it flat, and cover it with a sterile plastic film for ultraviolet sterilization for 5 days, lift off the film, and put it in a cool place, add microbial agents and mix well for later use;

[0043] ②Put the pyrethrum and roe in a non-ferrous container, soak it in warm water at a temperature of 10-20℃ for 30 minutes, with a water consumption of 5 times the weight of the raw material, place it on a smokeless stove, and seal the small fire. Decoc...

Embodiment 3

[0051] Example 3 Comprehensive use of biochemical resources to repair heavy metal contaminated soil, including pesticide spraying, earthworm enrichment and repair, and microbial decomposition. The insecticide is prepared from the following materials, all in parts by mass: 290 kg of organic fertilizer, 29 kg of microbial inoculants, 0.06 kg of pyrethrum, 0.05 kg of fish vine and 0.03 kg of Bacillus thuringiensis powder.

[0052] The preparation process of the insecticide is:

[0053] ①Put the organic fertilizer on a sterile plastic film, flatten it, cover it with a sterile plastic film, and sterilize it by ultraviolet light for 2 days, lift off the film, and put it in a cool place, add microbial agents and mix well for later use;

[0054] ②Put the pyrethrum and roe in a non-ferrous container, soak it in warm water at a temperature of 10-20℃ for 30 minutes, with a water consumption of 3.5 times the weight of the raw material, place it on a smokeless stove, and seal the small fire. De...

Abstract

The invention discloses a method for repairing heavy metal contaminated soil through biochemical resources. The method comprises three processes of insecticide spraying, earthworm enrichment repairing and microbiological degradation. The insecticide used in the insecticide spraying process comprises the following materials of, by mass, 280-320 parts of organic fertilizers, 28-32 parts of microorganism bacterium agents, 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 repairing the heavy metal contaminated soil through the biochemical resource, not only can fertilizer efficiency of soil be improved but also pests in the soil and on the surface of earth are killed, and moreover the microbiological degradation process is added, so that the effect is remarkable and operation is simple.

Description

[0001] Divisional application, original application number 2014105572312, application date 2014.10.21, titled method of comprehensively utilizing biochemical resources to restore heavy metal-contaminated soil. technical field [0002] 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 [0003] 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 toxici...
