Description
Technical field
This utility model relates to a kind of seawater treatment apparatus, a kind of integrates the extraction of uranium from seawater and desalinization
Device.
Background technology
Along with the development of nuclear industry, people are increasing to the demand of uranium ore resource, and the exploitation dynamics of uranium ore is also
Strengthen year by year.In recent years, the mining progress development of world's uranium ore is swift and violent.The most explored uranium ore is more at present, but wherein
The uranium ore with extraction value only accounts for the 12-18% of total amount, and the uranium ore major part of China is unavailable uranium ore.At present, at nuclear power station
In wide variety of presurized water reactor (such as Qinshan, Daya Bay nuclear power plant's heap-type of China) to the utilization rate of natural uranium resource the most about
1%, in world wide from the point of view of, the prospect of uranium resource is the most optimistic.Can exploit under 130 dollars/kilogram of the whole world at present
Uranium resource is only 5,300,000 tons, and this also implies that, these natural uraniums are merely capable of supplying the nuclear power station of 530 1,000,000 kilowatts and make
With 60 years, and the nuclear power station of 1,000,000 kilowatts that the current whole world is currently running was 372.Solve the uranium resource in global range short
Scarce problem is extremely the most urgent.With the presence of there being the uranium resource of Development volue in a large number in the middle of sea water, total amount is about 45 hundreds of millions tons.But due to
Sea water radix is excessive, and the concentration moment of uranium is diluted, and sea water intermediate ion is of a great variety, therefore extracts uranium from sea water and have the biggest
Difficulty is carried out the research of the extraction of uranium from seawater and is concentrated mainly on the exploitation aspect of adsorbent.
The water resource of China is not enriched, total owning amount about 2.7Tm3, the freshwater resources amount being available for developing is 1-
1.1Tm3, occupy the 6th, the world.If based on per capita, about the 1/4 of world's water yield per capita.It is classified as the 110th, the world.China is tight
The hydropenia big country of weight, ranks among the best in more than 40 serious water shortage countries.And, the spatial and temporal distributions of China's water resource is unbalanced,
The most incompatible with the Area distribution in arable land, population.Desalinization becomes one of important way obtaining freshwater resources.
During the existing extraction of uranium from seawater, there is following technical problem: problem 1: adsorbent have employed graininess, in application
In be not fixed easily, it is more difficult to reclaim.Problem 2: the material using the technology such as solid forming to prepare can affect the shape of former granular materials
Looks and performance.Problem 3 seldom accomplishes that in the extraction of uranium from seawater-desalination integration is carried out.
