Embodiment 1

[0029] This embodiment provides a treatment system for the organic phase of radioactive nuclear waste, including: a pretreatment unit, a wet catalytic oxidation treatment unit and an electrolytic oxidation treatment unit; wherein the pretreatment unit, the wet catalytic oxidation treatment unit and the electrolytic oxidation treatment unit are connected in sequence ; The pretreatment unit is used to dilute the waste organic phase to obtain a uniform waste organic phase; the wet catalytic oxidation treatment unit is used to oxidize the uniform waste organic phase to initially degrade the COD in the waste organic phase cr , to obtain catalytic oxidation wastewater; the electrolytic oxidation treatment unit is used to further remove COD in catalytic oxidation wastewater cr .

[0030] The organic phase with radioactive nuclear waste first passes through the pretreatment unit for pretreatment such as mixing, dilution, dosing, stirring, etc.; then enters the wet catalytic oxidation ...

Embodiment 2

[0038] This embodiment provides a treatment system for radioactive nuclear waste organic phase, such as figure 2 As shown, it includes: a pretreatment unit of waste organic phase, a wet catalytic oxidation treatment unit, an electrolytic oxidation treatment unit, and an evaporation concentration treatment unit, and the pretreatment unit, a wet catalytic oxidation treatment unit, an electrolytic oxidation treatment unit, and an evaporation concentration treatment unit are sequentially connect. specifically,

[0039] The pretreatment unit includes liquid inlet system, stirring system, mixing system and dosing system, etc. The liquid inlet system consists of two parts, one part is the waste organic phase liquid inlet, which enters the mixing system 5 through the waste organic phase liquid inlet pump 1; The two liquid phases enter the mixing system at the same time; since the waste organic phase belongs to the oil phase and is immiscible with water, an emulsifier needs to be ad...

Embodiment 3

[0047] This embodiment provides a treatment method for radioactive nuclear waste organic phase, waste organic phase COD cr About 1.3 million, including the following steps:

[0048] S1: First enter the pretreatment unit, pass through the water inlet pump and the product water of the evaporative concentration unit to mix and dilute in a certain proportion in the mixing system, and at the same time add a certain amount of emulsifier to the mixing system, and make it completely mixed and mixed in the state of stirring Emulsified to form a homogeneous spent organic phase. Wherein, the addition amount of the emulsifier is 2% of the mass of the waste organic phase, the stirring speed is 250 rpm, and the ratio of waste organic phase to water is 1:40.

[0049] S2: The uniform waste organic phase enters the wet catalytic oxidation system through the wet catalytic oxidation high-pressure liquid inlet pump and the air discharged from the air compressor, and then enters the preheater, re...

Abstract

The invention relates to a processing system and a method for a radioactive nuclear waste organic phase. The processing system comprises a pretreatment unit, a wet catalytic oxidation treatment unit,an electrolytic oxidation treatment unit and an evaporation concentration treatment unit, which are sequentially connected. In the treatment process, the waste organic phase is firstly implemented pretreatments such as mixing, dilution, dosing, stirring and the like by the pretreatment unit, and then the waste organic phase is entered into the wet catalytic oxidation unit and the CODcr in the waste organic phase is degraded, and most organic matters are catalytically oxidized into inorganic substances or macromolecules are catalytically oxidized into micromolecules; the water treated by the wet catalytic oxidation is entered into the electrolytic oxidation treatment unit again for an advanced oxidation treatment, and finally the organic phase is completely converted into an inorganic phaseto thoroughly realize a change of water into oil; because a small amount of radioactive uranium, phosphate radicals, nitrate radicals and the like are contained in the treated water, so that the uranium, the phosphate radicals and the nitrate radicals are recycled by the evaporation concentration processing unit; the technical problems of a nuclear industry for many years and a potential safety hazard of long-term storage of the waste organic phase are solved.

Description

technical field [0001] The invention relates to the technical field of nuclear environmental protection, in particular to a system and method for treating radioactive nuclear waste organic phase. Background technique [0002] Nuclear science and technology have been widely used in many fields such as industry, agriculture, medicine, and military affairs, bringing great convenience and benefits to people's production and life, and at the same time exerting great influence on people's health, the safety of the environment, and the development of future generations. Nuclear safety has become a topic of widespread concern, and the Fukushima nuclear accident in Japan not long ago has made people more worried about nuclear safety. During the development and utilization of nuclear science and technology, a large amount of radioactive waste will be produced, and the radioactive waste is organic. These radioactive waste water will cause water and soil pollution after entering the env...
