Embodiment Construction

[0022] Such as figure 1 The shown soil remediation device for removing omethoate components in farmland soil, the device includes 1-raw soil hopper, 2-blast separator, 3-vibrating screener, 4-magnetic screener, 5-grinding pulverizer , 6-three-stage microbial spray degradation reactor, 7-adjustable spray tower, 8-electric blast dryer, 9-restoration soil storage bin; among them, the farmland soil containing omethoate components to be repaired is concentrated It is stored in the raw soil hopper 1, where it is collected intensively and the preliminary stabilization process is completed. The soil to be repaired in the raw soil hopper 1 is transported to the blast separator 2 by a screw elevator conveyor, where the plastic, Paper and other low-density, large-volume debris, the outlet of the blast separator 2 is connected to the vibrating screening machine 3 through a conveyor belt, where impurities with high density and large particle size in the soil are removed, and the outlet of ...

Abstract

The invention discloses a soil remediation device capable of removing omethoate components in farmland soil. The device comprises an original soil hopper, a blast sorting machine, a vibrating screening machine, a magnetic screening machine, a grinding machine, a three-stage microbe spraying and degrading reactor, an adjusting type spray tower, an electric heating blast dryer and a remedied soil storage silo. The device 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 a 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 device for removing omethoate components in farmland soil, belonging 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 as...
