Movable evaporation pond for radioactive wastewater

Abstract

The invention belongs to the technical field of environment-friendly treatment equipment, and particularly relates to a radioactive wastewater movable evaporation pond which comprises a water tank pond, a greenhouse cover is fixedly mounted at the top of the water tank pond, and an internal circulation device is arranged in the water tank pond. According to the radioactive wastewater movable evaporation pond, closed control over the evaporation pond is achieved, and the evaporation pond is not affected by the external environment; meanwhile, a device for forcing convection of gas and liquid is adopted, so that the evaporation temperature is effectively increased, the air humidity is reduced, and the driving force of evaporation is accelerated; besides, the membrane technology is adopted, the huge surface area of the membrane is utilized, and the evaporation surface of the projection area is increased by several times, so that the treatment capacity is increased by dozens of times compared with that of a traditional evaporation pond, the influence of the use area is avoided, and the device becomes a universal efficient nuclide wastewater treatment edge tool; and the method has extremely wide application potential in waste water discharged by the nuclear industry in decommissioning of old evaporation ponds, newly built evaporation ponds and different areas.

Description

technical field [0001] The invention relates to the technical field of environmental protection treatment equipment, in particular to a mobile evaporation pond for radioactive waste water. Background technique [0002] Radioactive wastewater refers to waste liquid containing nuclides, usually containing radioactive elements, nitrates or hydrochlorides, and usually a large amount of acids and bases. It has strong radiation, is difficult to handle, and has a tendency to scale. In order to meet the needs of production separation and subsequent environmental protection, it is necessary to separate nuclide heavy metals from acids. In the traditional separation methods, a large number of neutralization precipitation methods, distillation methods, ion exchange resin methods, etc. are used, but because of the high acidity, the neutralization method will consume a large amount of alkali and generate a large number of secondary pollutants; distillation methods with high acidity Dist...

AI Technical Summary

Problems solved by technology

[0004] 1. Due to the low evaporation efficiency, the general evaporation pool occupies a large area, which limits its use, and can only be used with extremely cheap land.

[0005] 2. The following problems are caused by the open space, a. Secondary pollution to the outside air environment, such as air pollution caused by the release of dust and radiation that may be produced by the drying of radioactive substances, and the volatilization of a large number of pollutants

b. The problem of bird entry caused by the open type, which may cause possible pollution and spread

c. The problem of rainwater intrusion due to the opening

[0006] 3. Because the evaporation pool is an environment integrated with the external environment, there is no way to control the temperature and humidity. It is greatly affected by the external environment, and its application is limited by the region. It can only be used in areas with large evaporation and little rainfall.
