1. A method for storing nuclear waste water by using ice sources is characterized by comprising the following steps: by utilizing the characteristic of climate of the ice land below 0 ℃ for a long time all the year, pits are dug on the ice land and nuclear wastewater is filled into the pits to lead the ice land to be frozen into solid ice, thereby achieving the purposes of preventing the pollutants from leaking and storing the solid ice in a solid mode for a long time.

The technical field is as follows: this patent belongs to nuclear waste processing field.

Secondly, background art: along with the development of zirconium and hafnium industry and nuclear industry, nuclear wastewater with various concentrations and complex components generated by various industries is increasing day by day, a large amount of nuclear wastewater generated by a plurality of nuclear accidents is difficult to be effectively treated, a lot of nuclear wastewater is randomly discharged, bad influence is brought to the earth ecology, and the nuclear wastewater problem suffocates the development of zirconium mineral resources in China. The important strategic mineral production depends on import for a long time (because the radioactivity of the zirconium mine produced in China mostly exceeds the standard, and if the zirconium oxychloride is produced by the national zirconium mine wet method, a large amount of nuclear waste water exceeding the standard is generated). Especially when the amount of the sudden generation is large and the components are complex, the measures are not good enough and no good measures can be taken. Nuclear wastewater in nuclear power industry is well known: a tank of nuclear wastewater placed in fukushima, japan, wars Colosseus worldwide.

Thirdly, the invention content: the patent provides a new method aiming at the current technical situation: the nuclear waste water is transported to an ice source for storage, and the nuclear waste water is changed into a solid form for long-term storage (the nuclear waste ice).

The ice sources on our earth are roughly divided into two blocks: one in the Antarctic; one located in the Greenland island. Antarctic, because the nuclear banning treaty is currently temporarily unable to store nuclear waste water there (it is likely that the treaty will change as times evolve), remains viable as Greenland island. The brief introduction is as follows: the Greenland island ice sources are single ice covers covering nearly 80% of Greenland and about 171 ten thousand square kilometers, and the largest ice bodies of northern hemispheres. Covering on the dish-shaped basin, the surface of the bedrock is as high as the sea surface. The center of the ice field is thicker than the peripheral edges, and 2 rising ice domes are arranged. The length of the ice field in the north-south direction is 2400 kilometers, and the average thickness of an ice layer at the widest position of 1100 kilometers reaches 2000 meters. The ice sources have been insoluble for 11 million years, and at least one hundred thousand years can be expected to remain insoluble. Is ideal for storing nuclear waste water.

Fourthly, the technical scheme is as follows: digging a pit in an ice land, filling nuclear waste water transported by a super tanker elsewhere into the pit of the ice land (nucleating waste ice) through a pipeline, paying attention to the fact that the pit cannot be filled too fully, and taking a certain height difference reserved between a water level and the edge of the pit as a snow water storage pool to enable the accumulated snow water to be solidified into ice and then become a pit ice cover, namely the nuclear waste water level is at least five meters lower than the edge of the pit, and according to the theory that one meter of thick ice is accumulated in every 55 years (namely, 2000 meters in 11 ten thousand years), the time consumed by the ice cover with the depth of five meters is 275 years. The nuclear waste ice is solidified in the pit forever and does not leak. The shape of the pit is a crater shape, so that the ice on the outer edge is slightly melted and cannot flow into the pit. The nuclear waste ice formed by the nuclear waste water in the pit is stored in a solid form together with the ice sources for a long period of time as long as the ice sources are present, and is expected to remain undissolved for at least ten thousand years. See the attached drawings of the specification.

Fifthly, the beneficial effects are that: the method is used for clearing obstacles to the development of the native zircon mining in China that the zircon resources are abundant and live in the world 9 th, but most of the zircon is imported low-radioactivity zircon sand at present, and the zircon mining in China has high radioactivity except for the Shandong honor (zirconium hafnium metallurgy 537 th page) which is an extremely important reason in many aspects.

Also opens up a financial path for Greenland island which is poor and laggard, depends on Danish relief and has single economic dependence on fishery:unique Nuclear waste (water) storage yard. A new model is also found for arctic channel applications. Meanwhile, a new technical scheme is provided for reducing the radioactive pollution of the world, the sea, the rivers and the sea, the solid storage of the radioactive pollutants is the best and most common treatment method according to the current scientific level, and at present, 79 nuclear waste disposal sites exist internationally and belong to 34 countries. Nuclear waste depots in many developed countries are open worldwide and all receive significant income.

Sixth, the detailed implementation mode: the nuclear wastewater generated in the process of producing zirconium oxychloride by a wet method and the nuclear wastewater generated in nuclear accidents are primarily treated to remove impurities which are easy to filter, and the remaining nuclear wastewater containing radioactive impurities is concentrated and put in a storage tank to be transported. The super oil tanker is simply transformed to be capable of conveying nuclear waste water, the nuclear waste water of the super oil tanker is directly sucked by a pump and sent to an ice pit through a temporarily built pipeline when arriving beside the Greenland island (without a wharf), and one or more pits capable of containing the nuclear waste water are dug on the ice pit. The special ice-cube mining engineering company of Harbin of Heilongjiang, China, which is specially used for picking ice cubes, can be called to dig a pit (or blast the pit with explosive), and a pipeline/bracket and a plurality of conveying relay devices for conveying nuclear wastewater, such as a high-power water pump, a high-power diesel generator and the like, are arranged along the pipeline.

Seventhly, description of attached drawings: in the figure 1, the shape of the pit is similar to a crater shape, so that the ice and the raw ice outside are slightly melted and cannot flow into the pit. As long as the ice source exists, the nuclear waste ice formed by the nuclear waste water in the pit and the ice source are stored for a long time in a solid form, the nuclear waste water level is at least five meters lower than the edge of the pit, and the nuclear waste water level is reserved for long-time storage and covered with a thick ice cover formed by accumulated snow, namely, the water level (formed as the nuclear waste ice) and the certain height difference reserved at the edge of the pit are used as a snow water storage pool, so that the accumulated snow water is solidified into ice and then becomes the pit ice cover.
