Problems solved by technology

Its disadvantage is that it is easy to destroy soil organic matter and soil water, and it needs to consume a lot of energy
[0037] Due to the characteristics of large water volume and wide distribution of surface water, its pollution treatment cannot be concentrated like domestic sewage or industrial wastewater, using traditional coagulation sedimentation, adsorption, extraction, ion exchange, membrane separation and other treatment processes and equipment. treatment, which brings great difficulty to surface water pollution control

Abstract

The invention discloses a method for restoring a cadmium pollution environment, which comprises the step of planting a polypodiaceae plant in the cadmium pollution environment. The polypodiaceae plantis preferably microsorium pteropus. The method uses the polypodiaceae plant to restore the cadmium pollution environment, particularly the microsorium pteropus to restore the cadmium pollution waterbody and wetland ecosystem, and the method has the characteristics of convenience, attractive appearance, and strong restoration force.

Description

technical field [0001] The invention relates to a method for repairing cadmium-polluted environment, in particular to a method for repairing cadmium-polluted water bodies and / or wetland ecosystems by using plants of the family Aquapodiaceae. Background technique [0002] The toxicity of metal cadmium is very low. But its compounds are very toxic. Cadmium poisoning in the human body is mainly caused by ingesting cadmium-contaminated water, food, and air through the digestive tract and respiratory tract. Cadmium accumulates in the human body, and the latent time can be as long as 10-30 years. According to reports, when the cadmium in water exceeds 0.2mg / L, the residents drink water for a long time and ingest cadmium-containing substances from food, which can cause "bone pain disease". Animal experiments show that the minimum lethal dose for mice is 50 mg / kg, and the cadmium entering the human body and warm-blooded animals is mainly accumulated in the liver, kidney, pancreas,...
