How to treat nuclear sewage in China

At present, China mainly uses physical treatment, chemical treatment and irradiation treatment to treat nuclear wastewater, and through the formulation and supervision of laws and regulations to ensure the treatment of nuclear wastewater to meet the standards and safety.

The treatment method of nuclear waste water is as follows:

1, physical treatment method:

Degradation and dilution: Reduce the concentration and activity of pollutants by diluting or decomposing nuclear wastewater.

Precipitation filtration: removing suspended matter and precipitate by adding precipitant or filter material.

Adsorption and ion exchange: pollutants in nuclear wastewater are adsorbed or exchanged by adsorbents or ion exchangers.

2, chemical treatment method:

Chemical precipitation method: by adding chemicals to precipitate pollutants, solid-liquid separation is completed.

Chemical oxidation method: organic matter is oxidized by oxidant and degraded into harmless substances.

Ion exchange method: use ion exchange resin to remove impurity ions from nuclear waste water.

3, irradiation treatment method:

Electron beam irradiation: nuclear waste water is irradiated by electron beam to make organic matter undergo photolysis and electrolytic reaction to achieve the effect of degradation.

Measures and policies for nuclear waste water management;

1. Laws and regulations: People's Republic of China (PRC) Nuclear Safety Law and other laws and regulations have been formulated, and the requirements and responsibilities for nuclear wastewater treatment have been defined.

2. Supervision organization: A nuclear and radiation safety supervision organization was established to supervise and manage the treatment of nuclear wastewater.

3. International cooperation: strengthen exchanges and cooperation with international organizations and overseas nuclear energy countries to improve the technical level and safety of nuclear wastewater treatment.

4. Public participation: strengthen information dissemination and education for the public, and increase public understanding and participation in nuclear wastewater treatment and management.

The treatment and management of nuclear waste water is an important guarantee and environmental protection requirement for the sustainable development of nuclear energy. China has adopted various technical measures in nuclear wastewater treatment, and formulated a series of policies and regulations to ensure that nuclear wastewater treatment meets the standards and is safe. In the future, we should further strengthen technical research and innovation, improve the efficiency and safety of nuclear wastewater treatment, strengthen public participation and communication, and form a good atmosphere for the whole society to pay attention to and jointly treat nuclear wastewater.

Nuclear energy is an important part of China's energy structure adjustment. At the same time, the development of nuclear energy has also brought about the generation and disposal of nuclear waste. The treatment and management of nuclear wastewater involves national security, environmental protection and public health. It is of great significance to treat nuclear wastewater scientifically, standardly and safely.
