Problems solved by technology

[0004] The research on the remediation technology of heavy metal-contaminated soil is the focus of environmental protection engineering science and technology research. The physical and chemical methods commonly used in the remediation methods of heavy metal-contaminated soil have direct and rapid effects, but the persistence is poor. To repair the effect, but will appear new pollution
Using microbial technology plus organic matter treatment can achieve safe, long-lasting and comprehensive effects, but the general restorative agent only has a single function, and has no insect-proof, anti-bacteria and fertilizer-enhancing effects

Embodiment 1

[0032] Example 1 The soil remediation agent with the effect of treating heavy metal pollution and increasing fertilizer is mainly prepared from the following raw materials: 260 kg of organic fertilizer, 25 kg of microbial inoculum, 0.03 kg of difenoconazole, 0.05 kg of pyrethrum, and 0.03 kg of deervine , chlorothalonil 0.04 kg, Lactobacillus plantarum 0.02 kg.

[0033] The preparation steps of the above-mentioned soil remediation agent with both heavy metal pollution and fertilizer-enhancing effects are as follows:

[0034] (1) Put the organic fertilizer on a sterile plastic film, spread it flat, cover it with a sterile plastic film, sterilize it with ultraviolet light for 1 day, remove the film, put it in a cool place, add microbial agents and mix well for later use;

[0035] (2) Grind pyrethrum and deervine after drying, pass through a 100-mesh sieve, add water 300 times the amount of raw materials and stir for 20 minutes to obtain a suspension, spray it evenly on the fert...

Embodiment 2

[0038] Example 2 The soil remediation agent with the effect of treating heavy metal pollution and increasing fertilizer is mainly prepared from the following raw materials: 310 kg of organic fertilizer, 31 kg of microbial agent, 0.07 kg of difenoconazole, 0.1 kg of pyrethrum, and 0.09 kg of deervine , chlorothalonil 0.08 kg, Lactobacillus plantarum 0.06 kg.

[0039] The preparation steps of the above-mentioned soil remediation agent with both heavy metal pollution and fertilizer-enhancing effects are as follows:

[0040] (1) Put the organic fertilizer on a sterile plastic film, spread it flat, cover it with a sterile plastic film, sterilize it with ultraviolet light for 5 days, remove the film, put it in a cool place, add microbial agents and mix well for later use;

[0041] (2) Grind pyrethrum and deervine after drying, pass through a 160-mesh sieve, add water 400 times the amount of raw materials and stir for 60 minutes to obtain a suspension, spray it evenly on the fertil...

Embodiment 3

[0044] Example 3 The soil remediation agent with the effect of treating heavy metal pollution and increasing fertilizer is mainly prepared from the following raw materials: 270 kg of organic fertilizer, 27 kg of microbial inoculum, 0.04 kg of difenoconazole, 0.07 kg of pyrethrum, and 0.04 kg of deervine , chlorothalonil 0.05 kg, Lactobacillus plantarum 0.03 kg.

[0045] The preparation steps of the above-mentioned soil remediation agent with both heavy metal pollution and fertilizer-enhancing effects are as follows:

[0046] (1) Put the organic fertilizer on a sterile plastic film, spread it flat, cover it with a sterile plastic film, sterilize it with ultraviolet light for 2 days, remove the film, put it in a cool place, add microbial agents and mix well for later use;

[0047] (2) Grind pyrethrum and deervine after drying, pass through a 120-mesh sieve, add water 300 times the amount of raw materials and stir for 20 minutes to obtain a suspension, spray it evenly on the fe...

Abstract

The invention discloses a soil restoration agent with a heavy metal pollution treatment function and a fertilizing function and a preparation process of the soil restoration agent. The soil restoration agent is mainly prepared from the following raw materials in parts by weight: 260 to 310 parts of organic fertilizer, 25 to 31 parts of microbial agent, 0.03 to 0.07 part of difenoconazole, 0.05 to 0.1 part of pyrethrum, 0.03 to 0.09 part of rotenone, 0.04 to 0.08 part of chlorothalonil and 0.02 to 0.06 part of lactobacillus plantarum. The organic fertilizer is used as a main raw material, the microbial agent, insecticidal and sterilized vegetable drug and chemicals capable of alleviating the harm of soil heavy metal are added, so that not only can the fertilizer effect of the soil be improved, but also the soil restoration agent can enter the soil deeply to improve the heavy metal pollution and prevent the disease and insect pests.

Description

technical field [0001] The invention relates to the field of environmental protection and soil pollution control, and discloses a soil restoration agent with the functions of treating heavy metal pollution and increasing fertilizer and a preparation process thereof. Background technique [0002] Heavy metal pollution refers to environmental pollution caused by heavy metals or their compounds, mainly caused by human factors such as mining, waste gas discharge, sewage irrigation and the use of heavy metal products. Heavy metals are not easy to move and dissolve, and cannot be excreted after entering the organism, which will cause chronic poisoning. Different from the pollution of other organic compounds, heavy metals are enriched, and heavy metal pollution is difficult to degrade naturally. For example, heavy metals such as lead and cadmium enter the soil environment, which will accumulate for a long time and destroy the self-purification ability of the soil, making the soil a...
