Treatment methods of radioactive waste oil

Abstract

The invention discloses a treatment method of radioactive waste oil. The radioactive waste oil is mixed with water according to the volume ratio of 1:0.5 to 1:3 to obtain an oil and water mixture. Then the oil and water mixture is subjected to standing, and an oil phase and an aqueous phase containing radioactive substances are obtained after stratification. The oil phase and the aqueous phase areseparated, and the aqueous phase is treated to remove the radioactive substances. The treatment method of the radioactive waste oil is low in treatment cost and safe. The water treatment efficiency per unit volume is high, after treatment, less second radioactive waste is generated, the radioactive waste oil can be treated in batch and on a large scale, and the radioactive waste oil which is flammable, combustible and extremely high in danger level can be effectively treated.

Description

technical field [0001] The invention relates to the technical field of processing radioactive substances, in particular to a method for processing radioactive waste oil. Background technique [0002] With the development of society and economy, the demand for power resources is increasing, and nuclear power, as an efficient and clean energy source, has been more and more widely used. But while bringing huge economic benefits to people, the problem of the disposal of radioactive waste generated during the operation of nuclear power plants is also becoming more and more serious. [0003] Nuclear power plant-related wearing equipment needs lubricating oil, hydraulic oil, etc. during operation and maintenance. These oils will inevitably be polluted during use. Radioactive waste oil. Radioactive waste oil has a certain specific activity of radioactivity, and is itself a flammable substance. If it is not treated, it will cause great space pressure and management pressure for the...

Problems solved by technology

Although the above method can deal with radioactive waste oil, it is difficult to deal with the tail gas of the incineration method and has a great impact on the environment, which has been increasingly opposed

The adsorption method has high requirements on the performance of the adsorbent. At present, there is a lack of high-efficiency adsorbents in China, which need to be imported from abroad, and the processing cost is high.

The emulsification-solidification method has a large volume increase and produces a lot of secondary waste, and the development of emulsifiers is still immature, and the performance of the solidified body needs to be verified, so it cannot be formally used for the treatment of radioactive waste oil

[0005] In summary, the traditional treatment of radioactive waste oil is expensive, dangerous, and produces a lot of secondary radioactive waste after treatment, which is not suitable for batch and large-scale treatment of radioactive waste oil

Especially for the highly flammable and explosive radioactive waste oil, there is a lack of effective and efficient treatment methods
