Multidirectional repair treatment method based on uranium-contaminated water body

Abstract

The invention discloses a multidirectional repair treatment method based on a uranium-contaminated water body, and belongs to the technical field of water body uranium contamination repair treatment.The multidirectional repair treatment method based on the uranium-contaminated water body comprises the following steps: a plurality of water-soluble deformation filaments are inserted in the surfaceof a uranyl ion loaded imprinted polymer; the uranyl ion loaded imprinted polymer is dried; discharging is conducted, and imprinted fungal repair balls are obtained and put into the uranium-contaminated water body; and regular salvaging and centralized treatment are conducted, the water-soluble deformation filaments are attached to the surface of the granular uranyl ion loaded imprinted polymer, after the imprinted fungal repair balls are put into the water body, the water-soluble deformation filaments on the surface of the uranyl ion loaded imprinted polymer are partially separated from the imprinted fungal repair balls, filament layers are formed on the surfaces of the imprinted fungal repair balls, thus the imprinted fungal repair balls are similar to hair balls, the multiple hair-ball-shaped imprinted fungal repair balls mutually adhere, thus accumulation force is higher, subsequent smooth salvaging is facilitated, the salvaging missing amount is decreased, and the adverse effect on the water quality is avoided to the greatest extent.

Description

technical field [0001] The invention relates to the technical field of uranium pollution restoration and treatment of water bodies, and more specifically relates to a multidirectional restoration treatment method based on uranium-contaminated water bodies. Background technique [0002] Uranium is a radioactive substance and an important energy substance, which mostly exists in the form of uranyl ions (UO22+) in water and soil. With the rapid development of the nuclear industry and the decommissioning of waste nuclear facilities, some uranium (VI)-containing wastewater has brought serious harm to the environment and human beings. Uranium (VI) is usually accumulated in the human liver and bones by the food chain. Induce lung cancer, liver cancer, pancreatic cancer and other diseases. In the treatment of radioactive wastewater, especially wastewater containing uranium (VI), there are mainly coagulation precipitation, chemical precipitation, extraction, membrane separation, red...

Problems solved by technology

[0005] After the imprinted fungal material in the above technical solution repairs the uranium-contaminated water body, it needs to be salvaged for centralized treatment. However, the imprinted fungal material in the water has been subjected to the self-flow and impact of the water body for a long time, so it is relatively scattered, inconvenient to salvage, and often missed. of imprinted fungal materials remain in water bodies, affecting water quality
