Description
Technical Field
The invention relates to a soil pollution treatment device, in particular to a soil mercury removal device based on adsorbent extraction.
Background
Human activity causes mercury pollution in water, mainly from wastewater discharged by industries such as chlor-alkali, plastics, batteries, electronics and the like, and waste medical appliances. It was estimated that total mercury discharged into the soil by human activity was about 10 ten thousand tons worldwide in 1970 to 1979.
The harm of mercury to human health is related to the chemical morphology of mercury, environmental conditions, and the way and manner in which mercury invades the human body. The metallic mercury vapor has high diffusivity and high fat solubility, and can be completely absorbed by alveoli after invading the respiratory tract and transported to the whole body through blood. Metallic mercury in blood can enter brain tissue through the blood brain barrier and then be oxidized to mercury ions in brain tissue. Mercury ions are difficult to return to blood through the blood brain barrier, and thus gradually accumulate in brain tissue, damaging the brain tissue. Metallic mercury in other tissues may also be oxidized to ionic state and transferred to the kidneys for accumulation.
Mercury in the soil can volatilize into the atmosphere, and can also be flushed into ground water by precipitation and permeate into groundwater. Some mercury in the ground water enters the atmosphere due to volatilization, and most mercury is precipitated into the bottom mud. The mercury in the bottom mud is directly or indirectly converted into methyl mercury or dimethyl mercury under the action of microorganisms no matter what form the mercury is in. Dimethyl mercury can be decomposed into methyl mercury under acidic conditions. Methyl mercury is soluble in water and therefore returns from the substrate sludge to the water.
