Problems solved by technology

[0009] First, in the process of purifying the soil, there is a problem that there is no process for separating or purifying organic matter such as leaves mixed into the soil
[0010] Second, chemical purification agents are used, so additional equipment configuration costs for treating waste liquid generated during the purification process are required
[0011] Third, radioactive substances are mainly adsorbed on the fine soil, but it is not easy to separate the fine soil from the soil, so the purification of the soil cannot be effectively realized, and the soil with a low degree of pollution is also disposed of, so it has the potential to be restored to repeated The problem of low reduction rate of the used soil

Embodiment Construction

[0047] The terms or words used in this specification and claims should not be limitedly interpreted as conventional meanings or dictionary meanings, but should be based on the principle that the inventor can properly define the terms and concepts in order to explain his invention in the best way. Interpret the meaning and concept as conforming to the technical idea of ​​the present invention.

[0048] Below, refer to figure 1 A radioactive contaminated soil purification system according to a preferred embodiment of the present invention will be described.

[0049] The technical feature of the radioactive contaminated soil purification system is that the particle size of soil is classified more finely by physical classification by screen and blower, classification by water specific gravity, and classification by hydrocyclone.

[0050] That is, the smaller the particle size of the soil, the higher the adsorption rate of radioactive pollutants, but the fine soil with a small par...

Abstract

The present invention relates to a radioactive contaminated soil purification system, which provides a system including a pre-treatment filter unit, a drum screen group, an ejector, a hydrocyclone group and a waste liquid treatment unit The radioactive contaminated soil purification system, in more detail, relates to a radioactive contamination that separates gravel and organic matter through a screen and a blower, and only separates fine soil with a high degree of radioactive contamination to improve the purification efficiency and the reduction rate of reusable soil Soil purification system.

Description

technical field [0001] The present invention relates to a radioactive contaminated soil purification system, in more detail, relates to a radioactive contaminated soil purification system which improves the purification efficiency by separating fine soil with high radioactive contamination and improves the reduction rate of reducible reused soil. Background technique [0002] Generally speaking, the start-up and dismantling of atomic energy facilities will produce a large amount of radioactive soil. [0003] In particular, when unexpected accidents occur in nuclear power facilities due to various reasons such as management negligence and natural disasters, the surrounding soil will be polluted by radionuclides released from nuclear power facilities. [0004] As mentioned above, the soil contaminated by radioactive substances will firstly cause direct damage to humans and animals and plants living on land, and secondly, it will pollute the groundwater flowing in the soil, whi...
