Embodiment 1

[0022] Soil pre-treatment: Take the vegetable greenhouse soil with soil compaction, desertification, serious diseases, and cannot be planted as an example. When the temperature is above 10 degrees, apply 1 to 2 tons of organic fertilizer per mu and turn it into the soil with a rotary tiller , and sprinkle water to keep the soil moisture around 70%.

[0023] Soil remediation treatment: Combine the flora containing Acetobacter aceti, Acetobacter liquefaciens, Bacillus coagulans and Pseudomonas stutzeri with Molecular sieves are mixed to obtain biomolecular sieves, and then biomolecular sieves are mixed with the above soil at a mass ratio of 1:100. The particles are bonded together to form a good aggregate structure to facilitate the natural circulation of water, fertilizer, air, and heat, and the soil will not be compacted and desertified. When the temperature is above 15 degrees, the content of heavy metal ions will be reduced by 40% and the chemical residues will be reduced b...

Embodiment 2

[0026] Soil pre-treatment: Take the vegetable greenhouse soil with soil compaction, desertification, serious diseases, and cannot be planted as an example. When the temperature is above 10 degrees, apply 1 to 2 tons of organic fertilizer per mu and turn it into the soil with a rotary tiller , and sprinkle water to keep the soil moisture around 70%.

[0027] Soil remediation treatment: Combine the flora containing Acetobacter aceti, Acetobacter liquefaciens, Bacillus coagulans and Pseudomonas stutzeri with Molecular sieves are mixed to obtain biomolecular sieves, and then the biomolecular sieves are mixed with the above soil at a mass ratio of 3:100. The particles are bonded together to form a good aggregate structure to facilitate the natural circulation of water, fertilizer, air, and heat, and the soil will not be compacted and desertified. When the temperature is above 15 degrees, the content of heavy metal ions will be reduced by 40% and the chemical residues will be reduc...

Embodiment 3

[0030] Soil pre-treatment: Take the vegetable greenhouse soil with soil compaction, desertification, serious diseases, and cannot be planted as an example. When the temperature is above 10 degrees, apply 1 to 2 tons of organic fertilizer per mu and turn it into the soil with a rotary tiller , and sprinkle water to keep the soil moisture around 70%.

[0031] Soil remediation treatment: Mix the flora containing Pseudomonas putida, Lactobacillus plantarum and Lactobacillus rhamnosus with molecular sieves to obtain biomolecular sieves, and then combine biomolecular sieves with the above The soil is mixed evenly according to the mass ratio of 2.5:100, and the bacteria will act on the soil together to produce a colloidal substance "polysaccharide phosphate", which will bond all kinds of tiny particles in the soil together to form a good aggregate structure. In order to facilitate the natural circulation of water, fertilizer, air and heat, the soil will not be compacted and desertifi...

Abstract

The invention relates to a soil remediation method. The method comprises the following steps: (1) preparing biological molecular sieves by mixing molecular sieves and microorganisms; (2) uniformly mixing the biological molecular sieves and soil according to the mass ration of (1-3) to 100 to obtain primarily treated soil, and 50-70 days later, uniformly mixing the biological molecular sieves and the primarily treated soil according to the mass ratio of (1-3) to 100. The biological molecular sieves obtained according to the method disclosed by the invention have good adsorption and ion exchange properties, meet the requirements of soil remediation and improvement, and enhance microorganism groups of the soil; the biological molecular sieves can be directly used as a soil amendment to improve the supply condition of beneficial trace elements required by crops, reduce the soil sourness and improve the base exchange capacity of soil, the content of heavy metal ions can be reduced by 40 percent in about 20 days, and the chemical residues can be reduced by 50 percent; and the biological molecular sieves can be used for improving the soil structure, regulating the PH value and chemical and physical properties, and degrading deposited chemicals and organic substances.

Description

technical field [0001] The invention belongs to the technical field of soil restoration, and in particular relates to a soil restoration method. Background technique [0002] There are various types of soil pollution in my country, showing the coexistence of new and old pollutants, and the combination of inorganic and organic pollution. There are not only heavy metals, pesticides, antibiotics, and persistent organic substances, but also pollution types such as radioactivity and pathogenic bacteria. There are many ways of soil pollution, the reasons are complicated, and the control is difficult. [0003] In the past 20 years, with the rapid development of social economy and high-intensity human activities, the area of ​​soil pollution in my country has been expanding, the soil quality has continued to deteriorate and the damage has become more serious, which has affected the comprehensive construction of a well-off society and the realization of sustainable development.
