Embodiment Construction

[0022] Such as figure 1 The soil remediation method for removing the omethoate component in the shown farmland soil, the farmland soil containing the omethoate component to be repaired is stored in the original soil hopper 1, and the centralized collection is carried out here and the preliminary stabilization process is completed. The original soil hopper The soil to be repaired in 1 is transported to the blast separator 2 through the screw conveyor, where the plastic, paper and other low-density and large-volume debris in the soil are removed. The outlet of the blast separator 2 is connected to the vibration separator by a conveyor belt. The screening machine 3 removes impurities with high density and large particle size in the soil. The outlet of the vibrating screening machine 3 is connected to the magnetic screening machine 4 through a conveyor belt. Metal impurities in the soil are removed here. The exit of the magnetic screening machine 4 passes through the conveyor belt....

Abstract

The invention discloses a soil remediation method capable of removing omethoate components in farmland soil. The method has the advantages that by creatively utilizing microbial degradation reaction of bacillus cereus, with participation of transphosphorylase, C-P bonds in the main components, O,O-dimethyl-S-[2-(methylamino)-2-oxo-ethyl] thiophosphate molecules, in omethoate, are broken and the main components are gradually degraded into harmless simple compounds, such as CO2, N2 and H2O, in a temperature range of 35-38 DEG C; the soil purified through microbial degradation can be repeatedly applied to agricultural production; meanwhile, no toxic chemical substances are used or generated in the method, thus basically putting an end to secondary harm to the environment in the soil remediation process.

Description

technical field [0001] The invention relates to a soil restoration method for removing omethoate components in farmland soil, and belongs to the field of soil restoration in environmental protection. Background technique [0002] Organophosphorus pesticides are the main category of pesticides today. Because they are economical, efficient, and convenient for the control of agricultural pests, they are mass-produced and widely used worldwide. After the application of organophosphorus pesticides, they will continue to spread from the spraying area to the surroundings, and enter the soil, water, air, and plant systems, causing serious pollution to the water environment, soil environment, atmospheric environment, and vegetation. Organophosphorus pesticides have an inhibitory effect on cholinesterase in organisms, making them lose the ability to decompose acetylcholine, resulting in the accumulation of acetylcholine, causing nerve dysfunction, and causing damage to the body, such ...
