Embodiment 1

[0029] This embodiment is used to treat uranium-containing aqueous solution with a uranium concentration of 20 ppm. The uranium adsorption material in this embodiment is amidoxime-based polyethylene grafted by irradiation. There are 10 groups of parallel adsorption columns in this embodiment. The specific process is as follows:

[0030] a. The uranium-containing aqueous solution with a uranium concentration of 20 ppm enters the pretreatment system 2 at a flow rate of 5 L / min and enters the tank adsorption system 4 at a flow rate of 1 L / min through the liquid distribution system 1 through the water pump 16;

[0031] b. The uranium-containing aqueous solution is firstly filtered through the filter 21 in the pretreatment system 2, and then enters the temperature-controlled water tank 22. The uranium-containing aqueous solution is heated to 30°C by the heater 27 in the temperature-controlled water tank 22, and then enters the buffer through the booster pump 25 Tank 26, the uranium...

Abstract

The invention discloses an adsorption device of uranium in a water solution. The adsorption device comprises a liquid preparation system, a pretreatment system, a column adsorption system, a groove type adsorption system and a waste liquid treatment system, wherein the adsorption device uses a multiple group parallel operation process in of two kinds of different modes of adsorption ways; the controllable process on of the adsorption conditions is realized; in addition, the parallel comparison checking screening can be performed at the same time by on a plurality of groups of uranium adsorption materials at the same time. The adsorption device of the uranium in the water solution solves the problem of shortage of seawater uranium adsorption material performance checking and uranium-containing waste water treatment process lack.

Description

technical field [0001] The invention belongs to the technical field of extracting uranium from seawater, and in particular relates to an adsorption device for uranium in aqueous solution. Background technique [0002] As global resources dwindle and the population continues to increase, in order to prevent social, political and environmental factors from affecting energy supply security and causing global economic problems, people have begun to explore and utilize unconventional forms of industrial metals and minerals reserves. The main source of uranium is pitchblende U 3 o 8 , the distribution of uranium ore is relatively concentrated, and only 15 countries have economically exploitable uranium ore reserves that can meet the requirements for the development of nuclear power generation, of which Australia and Kazakhstan account for 33%. At the current consumption rate of uranium resources, the global uranium resource reserves can sustain the development of nuclear power f...
