Problems solved by technology

At present, in operating nuclear power plants, after the laundry wastewater is collected together with wastewater from other sources, evaporation is often used for treatment. The evaporation system has a complex structure, high energy consumption and high operating costs.
When the wastewater source is single (only laundry wastewater exceeding the standard), it is less economical to set up a separate evaporation system

Embodiment Construction

[0013] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0014] As shown in the figure, the system for treating radioactive laundry wastewater exceeding the standard in this embodiment includes a bag filter 1, an activated carbon filter and a zeolite filter 2, and the outlet of the bag filter 1 is connected to the inlet of the activated carbon filter. The outlet of the activated carbon filter is connected with the inlet of the zeolite filter 2.

[0015] When the radioactive laundry waste water treatment system in this embodiment is working, the radioactive laundry waste water passes through the bag filter 1, the activated carbon filter and the zeolite filter 2 in sequence, and the waste water is stored in the discharge value storage tank after being treated by each filter.

[0016] In this embodiment, the filter bag filter 1 can effectively remove suspended solids and large particles of impurities in the laun...

Abstract

The invention discloses a system for treating overproof radioactive laundry waste water, which comprises a bag filter, an active carbon filter and a zeolite filter; the outlet of the bag filter is connected with the inlet of the active carbon filter; and the outlet of the active carbon filter is connected with the inlet of the zeolite filter. According to the system for treating the overproof radioactive laundry waste water, the bag filter can effectively remove suspended solids and large particle impurities in laundry waste water; the active carbon filter can remove surface active agent and micromolecule organics in the waste water to further retain the suspended solids in the water and can eliminate toxic action of organic macromolecule such as the suspended solids generated during washing clothes, synthetic detergent in the waste water and the like; the zeolite filter has good ion exchange characteristic and can effectively remove radionuclide ions (cesium and strontium) in lower radioactive waste water. The system for treating the overpoorf radioactive laundry waste water is simple in structure, low in energy consumption and operating cost and high in treating quality for the overproof radioactive laundry waste water.

Description

technical field [0001] The invention relates to the technical field of radioactive waste water treatment, in particular to a treatment process system for treating excessively radioactive laundry waste water. Background technique [0002] The environmental safety of nuclear waste is a major issue related to the sustainable development of nuclear energy. At present, China is implementing the "Active Development of Nuclear Power" plan, and the radioactive waste generated by the nuclear energy industry must be properly treated and disposed of. At present, in operating nuclear power plants, after laundry wastewater is collected together with wastewater from other sources, evaporation is often used for treatment. The evaporation system has a complex structure, high energy consumption, and high operating costs. When the wastewater source is single (only laundry wastewater exceeding the standard), it is less economical to set up a separate evaporation system. Contents of the inve...
