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 the effect of treating heavy metal pollution and increasing fertilizer is mainly prepared from the following raw materials: 260kg of organic fertilizer, 25kg of microbial agent, 0.03kg of difenoconazole, 0.05kg of pyrethrum, 0.03kg of deer vine, Bacterial cleanser 0.04kg, Lactobacillus plantarum 0.02kg.

[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 ob...

Embodiment 2

[0039] 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: organic fertilizer 310kg, microbial agent 31kg, difenoconazole 0.07kg, pyrethrum 0.1kg, deer vine 0.09kg, hundred Bacterial cleanser 0.08kg, Lactobacillus plantarum 0.06kg.

[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 ...

Embodiment 3

[0045] 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: 270kg of organic fertilizer, 27kg of microbial agent, 0.04kg of difenoconazole, 0.07kg of pyrethrum, 0.04kg of deer vine, Bacterial clear 0.05kg, Lactobacillus plantarum 0.03kg.

[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 obta...

Abstract

The invention discloses a soil remediation agent with the heavy metal pollution treatment and fertilization effects and a preparation method thereof.The soil remediation agent is mainly prepared from, by mass, 260-310 parts of organic fertilizer, 25-31 parts of a microbial agent, 0.03-0.07 part of difenoconazole, 0.05-0.1 part of pyrethrum, 0.03-0.09 part of derris, 0.04-0.08 part of chlorothalonil and 0.02-0.06 part of lactobacillus plantarum.According to the soil remediation agent, the organic fertilizer serves as a main raw material, the microbial agent capable of reducing heavy metal in soil and the plant pesticides and chemicals capable of killing pests and bacteria are added, and thus the soil remediation agent can improve the fertilizer effect of soil and can also penetrate deep into soil to relieve heavy metal pollution and prevent and treat pest and disease damage.

Description

[0001] Divisional application, original application number 2014105572670, application date 2014.10.21, titled 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 pollut...
