Embodiment 1

[0024] A method for soil remediation, comprising the following steps: (1) soil filtration: use excavation equipment to dig up soil containing garbage, and directly filter the soil through the excavation equipment to remove the garbage in the soil, and complete the soil treatment. (2) Soil disinfection: add soil disinfectant to the soil treated in step (1), stir the soil and soil disinfectant by excavating equipment, and perform a second step on the soil during the stirring process. After the first filtration, the stirring was completed and the reaction was left to stand for 24h; the input amount of the soil disinfectant was 2.5kg per mu; specifically, the soil disinfectant was composed of the following weight components: 10 parts of phosphates, 10 parts of plant ash , 8 parts of vermicompost, 5 parts of dimethyl disulfide, and 5 parts of sulfonamides.

[0025] (3) Soil remediation: add soil remediation agent to the soil treated in step (1), stir the soil and soil remediation a...

Embodiment 2

[0036] A method for soil remediation, comprising the following steps: (1) soil filtration: use excavation equipment to dig up soil containing garbage, and directly filter the soil through the excavation equipment to remove the garbage in the soil, and complete the soil treatment. (2) Soil disinfection: add soil disinfectant to the soil treated in step (1), stir the soil and soil disinfectant by excavating equipment, and perform a second step on the soil during the stirring process. Filtered for the second time, left to stand for 72h after stirring; the input amount of the soil disinfectant was 3.5kg per mu; specifically, the soil disinfectant was composed of the following weight components: 20 parts of phosphates, 15 parts of plant ash , 10 parts of vermicompost, 8 parts of dimethyl disulfide, and 8 parts of sulfonamides.

Embodiment 3

[0040] A method for soil remediation, comprising the following steps: (1) soil filtration: use excavation equipment to dig up soil containing garbage, and directly filter the soil through the excavation equipment to remove the garbage in the soil, and complete the soil treatment. (2) Soil disinfection: add soil disinfectant to the soil treated in step (1), stir the soil and soil disinfectant by excavating equipment, and perform a second step on the soil during the stirring process. After the first filtration, the stirring was completed and the reaction was left to stand for 48h; the input amount of the soil disinfectant was 3.5kg per mu; specifically, the soil disinfectant was composed of the following weight components: 15 parts of phosphates, 10 parts of plant ash , 8 parts of vermicompost, 8 parts of dimethyl disulfide, and 5 parts of sulfonamides.

[0041] (3) Soil remediation: add soil remediation agent to the soil treated in step (1), stir the soil and soil remediation a...

Abstract

The invention discloses a method for soil remediation. The method for soil remediation comprises the following step of (1) soil filtering, specifically, soil containing garbage is excavated and loosened through an excavator and then is subjected to primary filtering through a filtering net, and after being filtered, the soil is flattened again through the excavator. By carrying out primary filtering on the to-be-remediated soil, most solid substances, particularly metal and plastic products incapable of being naturally decomposed, can be filtered out, and thus the soil keeps clean; remediationis conducted by planting poplars, the effect that plants absorb part of elements in the soil can be effectively promoted, and thus overhigh sulfur and phosphorus elements in the plants are reduced; and meanwhile, grass has strong vitality, grow rapidly and can also be converted into nutrient substances after death.

Description

technical field [0001] The invention belongs to the technical field of soil remediation, and in particular relates to a method for soil remediation. Background technique [0002] Soil remediation is a technical measure to restore the normal function of contaminated soil. The overall situation of China's soil environment is not optimistic. The national soil pollution exceeding rate is 16.1%. While the soil environment problems of industrial and mining wasteland are prominent, the soil environment quality of cultivated land is even more worrying. And due to the rapid development of industry, not only more and more garbage remains in the soil, but also the pollution of heavy metals has become more and more serious, which has seriously damaged the ecological environment and environmental quality, and even many heavy metals will be brought into the human body through food. affect people's health. [0003] And in the process of restoration, special screening equipment needs to b...
