Treatment device and method for cadmium-contaminated soil

Abstract

The invention belongs to the technical field of cadmium-contaminated soil treatment, and discloses a cadmium-contaminated soil treatment device and a method thereof, and the cadmium-contaminated soiltreatment device comprises a cadmium pollution detection module, a main control module, a soil turning module, an improvement module, a planting module, a watering module, an analysis module, an alarmmodule and a display module. The modifier prepared by the modifier preparation method provided by the invention is added with a high-molecular compound, so that the form of cadmium in soil is changed, the toxicity of cadmium is reduced, and the absorption of plants to cadmium is reduced; meanwhile, the emission source is divided into a plurality of levels through the analysis module, and the environmental medium is divided into a plurality of classes; the total amount of the heavy metal cadmium discharged to different media is calculated, the total discharge amount of all pollution sources can be known, the contribution of the total discharge amount of the pollution sources to pollution is comprehensively mastered, pollution treatment is facilitated, and the analysis accuracy of the cadmium pollution sources is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of cadmium-contaminated soil treatment, and in particular relates to a treatment device and method for cadmium-contaminated soil. Background technique [0002] At present, cadmium is a non-essential element for the human body. It often exists in the form of compounds in nature, and its content is generally very low. Under normal environmental conditions, it will not affect human health. Cadmium and zinc are congener elements, and cadmium often coexists with zinc and lead in nature. When the environment is polluted by cadmium, cadmium can be enriched in organisms and enter the human body through the food chain to cause chronic poisoning. Under normal circumstances, naturally occurring cadmium will not cause harm to humans, but cadmium introduced by human factors will cause harm to humans. Cadmium in soil is divided into two categories: soluble and water-insoluble, and the two can be transformed into each ot...

Problems solved by technology

However, the existing treatment devices for cadmium-contaminated soil have poor effect on soil improvement; at the same time, the existing treatment devices for cadmium-contaminated soil cannot accurately analyze the pollution source

[0003] Through the above analysis, the problems and defects of the existing technology are: the existing cadmium-contaminated soil treatment device has poor soil improvement effect; at the same time, the existing cadmium-contaminated soil treatment device cannot accurately analyze the pollution source
