Problems solved by technology

[0005] 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

[0033] Example 1 The soil remediation agent with both heavy metal pollution and fertilizer-enhancing effects 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, fish Rattan 0.03kg, chlorothalonil 0.04 kg, Lactobacillus plantarum 0.02 kg.

[0034] The preparation steps of the above-mentioned soil remediation agent with both heavy metal pollution and fertilizer-enhancing effects are as follows:

[0035] (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;

[0036] (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 fertilizer obtained in...

Embodiment 2

[0039] Example 2 The soil remediation agent with both heavy metal pollution and fertilizer-enhancing effects is mainly prepared from the following raw materials: 310 kg of organic fertilizer, 31 kg of microbial inoculum, 0.07 kg of difenoconazole, 0.1 kg of pyrethrum, fish Rattan 0.09 kg, chlorothalonil 0.08 kg, Lactobacillus plantarum 0.06 kg.

[0040] The preparation steps of the above-mentioned soil remediation agent with both heavy metal pollution and fertilizer-enhancing effects are as follows:

[0041] (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;

[0042] (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 fertilizer obtained i...

Embodiment 3

[0045] Example 3 The soil remediation agent with both heavy metal pollution and fertilizer-enhancing effects is mainly prepared from the following raw materials: 270 kg of organic fertilizer, 27 kg of microbial agent, 0.04 kg of difenoconazole, 0.07 kg of pyrethrum, fish Rattan 0.04kg, chlorothalonil 0.05 kg, Lactobacillus plantarum 0.03 kg.

[0046] The preparation steps of the above-mentioned soil remediation agent with both heavy metal pollution and fertilizer-enhancing effects are as follows:

[0047] (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;

[0048] (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 fertilizer obtained in s...

Abstract

The invention discloses a soil remediation agent for treating heavy metal contaminated soil. The soil remediation agent is prepared from, by mass, 260-310 parts of organic fertilizer, 25-31 parts of microorganism bacterium agent, 0.03-0.07 part of difenoconazole, 0.05-0.1 part of pyrethrum, 0.03-0.09 part of trifoliate jewelvine roots or stems, 0.04-0.08 part of chlorothalonil and 0.02-0.06 part of lactobacillus plantarum. According to the soil remediation agent for treating the heavy metal contaminated soil, the organic fertilizer serves as the main raw material, the microorganism bacterium agent capable of reducing soil heavy metals and the vegetable drug and chemicals capable of killing insects and achieving sterilization are added, not only can the soil fertilizer efficiency be improved, but also the soil remediation agent can penetrate into the soil, heavy metal contamination is improved, and diseases and insect pests are prevented and treated.

Description

[0001] Divisional application, original application number 2014105572670, application date 2014.10.21, name Soil remediation agent and preparation process with both heavy metal pollution treatment and fertilization effects. technical field [0002] 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 [0003] 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 pollutio...
