Movable efficient volume reduction combined tool and method for low-radioactivity wastewater

Abstract

The invention discloses a movable efficient volume reduction combined tool and method for low-radioactivity wastewater, the combined tool is arranged on a shelter vehicle body, and a concentrated solution outlet of a pretreatment unit is connected with an inlet of a multi-stage reverse osmosis unit; a concentrated solution outlet of the multi-stage reverse osmosis unit is connected with an inlet of the continuous electrodeionization unit; a purified liquid outlet of the continuous electrodeionization unit is connected with an inlet of the electrodialysis unit; a concentrated water outlet of the electrodialysis unit is connected with an inlet of the MVR evaporation unit; a purified liquid outlet of the MVR evaporation unit is connected to an inlet of the in-barrel drying unit, and the MVR evaporation unit and a wastewater treatment device are integrated on the same square cabin vehicle body, so that the purpose of conveniently transferring and treating wastewater is achieved; a better water filtering and treating effect is achieved by utilizing a multi-stage reverse osmosis design; and by utilizing drying in the barrel, the occupied area of the treated pollutants is reduced, the treatment cost is reduced, and the radioactive waste is minimized.

Description

technical field [0001] The invention belongs to the technical field of low-radioactive waste water treatment, and in particular relates to a movable low-radioactive waste water high-efficiency volume reduction combined tooling. Background technique [0002] In today's world, nuclear energy has become an extremely widely used energy source. It has rapid development and active applications in both visible and invisible fields. However, the inherent properties of nuclear determine that in the event of natural disasters or man-made damage, it is bound to cause serious damage. And far-reaching impact, in order to protect the environment and human health, and achieve sustainable development, whether it is the emergency treatment of nuclear accidents, or the operation and decommissioning of nuclear power plants and nuclear facilities, the large amount of low-radioactive waste water produced by them must be safely, Economical and efficient handling. Among all treatment methods, in-...

AI Technical Summary

Problems solved by technology

[0011] For existing technologies that do not meet the principle of radioactive waste minimization; increase disposal costs; occupy more storage / disposal space; treatment equipment occupies a large area and is inconvenient to move, so that wastewater treatment in remote areas is not timely Problem, the present invention proposes a high-efficiency capacity-reducing combined tooling for movable low-radioactive waste water. Use multi-stage reverse osmosis design to achieve better filtration and treatment of water; use the drying and counting in the barrel to reduce the area of ​​pollutants after treatment, reduce disposal costs, and minimize radioactive waste
