Abstract

The invention discloses a soil remediation method which comprises the following steps of 1), soil filtration. In the step 1), soil containing garbage is loosen by an excavator, the soil is primarily filtered by the aid of a filter screen, and after filtration is completed, the excavator is used for leveling the soil again. The soil to be restored is primarily filtered, so that most of solid matters can be filtered out, especially metal and plastic products which cannot be naturally decomposed, and thus the soil can be kept clean. The soil is recovered by various plants, so that the elements inthe soil can be effectively absorbed by the plants, and excessive sulfur and phosphorus elements in the plants can be reduced. Meanwhile, grass has strong vitality, quickly grows, and can be converted into nutrient substances after death.

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] Soil remediation is a technical measure to restore the normal function of polluted soil. According to the "National Soil Pollution Survey Bulletin" released in 2014, the overall soil environment in China is not optimistic, and the national soil pollution rate exceeds the standard by 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 is becoming more and more serious, which seriously damages the ecological environment and environmental quality, and even many heavy metals are brought into the human body through food. affect people's health. Therefore, the re...
