Problems solved by technology
[0005] (1) For the mined uranium mines, many uranium-related waste ores were produced after mining, which caused the local soil to contain low amounts of radioactive elements, posing a certain threat to the local ecology and human life and health
[0006] (2) The operation and maintenance cost of the existing LCD liquid crystal display is relatively high, and the operation and maintenance efficiency is low

Embodiment Construction
[0043] In order to further understand the content, features and effects of the present invention, the following examples are given, and detailed descriptions are given below with reference to the accompanying drawings.
[0044] The structure of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0045] Such as figure 1 As shown, the method for using functional plant communities to restore uranium-contaminated soil provided by the embodiments of the present invention includes the following steps:
[0046] S101: Seed pretreatment of plant communities: Aiming at the size relationship of plants with strong ability to adsorb uranium in the soil, select sunflower, Indian mustard, two-finch, broken rice sedge and golden retriever plants to plant in the soil for adsorption of soil uranium in. Before sowing, the seeds of the plants are washed with sulfuric acid, then washed with water to remove the sulfuric acid, and wait for natur...

The invention belongs to the technical field of environmental protection and discloses a method of restoring uranium-contaminated soil by utilizing a functional plant community. Uranium in the soil issubjected to plant community adsorption through four steps of seed pretreatment of the plant community, sowing and planting of the plant community, trimming and fertilization of the plant community,and harvesting and centralized treatment of the plant community, so that the restoring purpose is achieved. Soil uranium concentration detection equipment used in the conducting process of the methodis used for detecting the soil uranium concentration and is provided with a detection equipment base; and a detection positive electrode and a detection negative electrode are fixed to the underneathof the detection equipment base through welding. Through plantation of the plant community, the soil polluted by the uranium is adsorbed and restored simply and effectively, and threat of the soil polluted by the uranium on an ecological environment and life health of a human body is reduced. The uranium content of the soil polluted by the uranium is simply and rapidly measured through the soil uranium concentration detection equipment, so that the density of sowing seeds is informed accurately.
Description
technical field [0001] The invention belongs to the technical field of environmental protection, and in particular relates to a method for repairing uranium-contaminated soil by using functional plant communities. Background technique [0002] Uranium is generally regarded as a rare metal. Although it is abundant in the earth's crust, it is difficult to extract uranium. The chemical properties of uranium are relatively active, and it always exists in the form of compounds. The distribution of uranium element is quite wide, but the distribution of uranium ore is very limited. [0003] At present, a large amount of uranium waste rock, uranium tailings and uranium-containing wastewater are produced in the mining of uranium ore. Due to the influence of various factors in the environment, uranium pollutants have caused serious soil pollution in the local mining area, causing the local soil to have low levels of radioactive elements, endangering the health of the surrounding peop...
