Description
Technical Field
The invention relates to the technical field of soil remediation, in particular to an energy-saving remediation device for cadmium-contaminated soil remediation and a remediation method thereof.
Background
Soil pollutants can be broadly divided into two broad categories, inorganic pollutants and organic pollutants. The inorganic pollutants mainly comprise acid, alkali, heavy metal, salts, compounds of radioactive elements cesium and strontium, compounds containing arsenic, selenium and fluorine, and the like. The organic pollutants mainly comprise organic pesticides, phenols, cyanides, petroleum, synthetic detergents, 3, 4-benzopyrene, harmful microorganisms brought by municipal sewage, sludge and manure, and the like. When the soil contains excessive harmful substances and exceeds the self-cleaning capacity of the soil, the composition, the structure and the function of the soil are changed, the activity of microorganisms is inhibited, and the harmful substances or decomposition products thereof are gradually accumulated in the soil and are indirectly absorbed by the human body through the soil → plants → the human body or through the soil → water → the human body, so that the degree of harming the health of the human body is reached, namely the soil pollution.
The soil is a loose surface layer having fertility on the surface of the land and capable of growing plants, and the thickness of the soil is generally about 2 m. The soil not only provides mechanical support capability for plant growth, but also provides fertility factors such as water, fertilizer, gas, heat and the like required by the growth and development of the plant. As the population is rapidly increased and the industry is rapidly developed, solid wastes are continuously stacked and dumped on the surface of soil, harmful waste water continuously permeates into the soil, and harmful gas and floating dust in the atmosphere continuously fall into the soil along with rainwater, so that the soil pollution is caused. All substances which hinder the normal function of soil, reduce the yield and the quality of crops and indirectly influence the health of human bodies through grains, vegetables, fruits and the like are called soil pollutants.
The cadmium content of the soil per kilogram is 0.01-2 mg, and the average content of the cadmium per kilogram is 0.35 mg. The cadmium concentration in the soil near the aluminum smelter and in the downwind area is very high, causing waste land. The cadmium-containing waste residue is accumulated, so that cadmium compounds enter soil and water. Phosphate fertilizers are applied in a wide and large quantity, so that cadmium from phosphate fertilizers and certain pesticides in soil, crops and food may exceed cadmium from other pollution sources in the long term.
The equipment for treating cadmium pollution in the market is expensive, the cadmium pollution is treated in a single treatment mode, the treatment effect is poor, the cadmium pollution in soil needs to be reduced in a plurality of combined modes, the equipment is expensive, the existing cadmium pollution treatment equipment is low in working efficiency, production and life of farmers are affected, and the equipment is rarely put into use, so that economic and energy-saving equipment is needed to rapidly treat the problem of cadmium pollution in soil.
