Quick Details

Nuclear industry wastewater presents an extremely complex composition, integrating radioactive hazards, chemical toxicity, and long-term environmental risks. Its safe and thorough treatment represents a global challenge restricting the sustainable development of the industry. This wastewater typically contains multiple radioactive nuclides such as uranium, plutonium, cesium, and strontium, as well as chemical substances like nitrate, boric acid, and organic complexing agents. It is characterized by strong radioactivity, high salinity, high toxicity, and poor biodegradability. Conventional processes like chemical precipitation and evaporation can achieve partial purification but often face challenges including lengthy treatment chains, generation of large volumes of secondary radioactive waste, and limited removal of organic pollutants, failing to fully meet increasingly stringent requirements for clean production and environmental safety.

To address this cutting-edge challenge, based on our extensive expertise in electrochemical advanced oxidation technologies, our company has successfully developed EC electrochemical equipment and the CQDHX SERIES EO electrochemical oxidation core systems, along with integrated processes tailored for nuclear industry wastewater characteristics. This technological approach avoids direct reliance on chemical reagent addition, opening an efficient and clean innovation pathway for deep purification, volume reduction, and safe disposal of nuclear wastewater.

The core of this process lies in our company's independently developed CQDHX SERIES EO electrochemical oxidation equipment and specialized EC electrochemical devices. Engineered based on proven catalytic oxidation and electrochemical flocculation principles, the EC electrochemical unit precisely controls the electrolysis process to generate efficient multinuclear hydroxy complexes and flocculants. These effectively break the complexation states between radioactive nuclides and organic compounds, enabling high-efficiency co-precipitation removal of colloids, suspended solids, and partial heavy metals. Following this, the CQDHX electrochemical oxidation equipment, featuring patented electrode structure design and optimized reactor flow fields, continuously and stably produces strong oxidative active species like hydroxyl radicals (·OH). These radicals perform non-selective attacks and deep mineralization on residual refractory organics such as organic solvents, detergents, and complexing agents, significantly eliminating chemical toxicity.

Our equipment transforms cutting-edge electrochemical theory into industrial products capable of withstanding extreme working conditions, achieving two core advantages: full-process cleanliness and inherent safety enhancement. Entirely driven by electric energy without requiring large chemical reagent dosing, the treatment chain fundamentally avoids salt accumulation and new sludge generation caused by reagent introduction, while optimized reaction pathways minimize secondary solid waste production. Constructed with radiation-resistant, corrosion-resistant specialty materials and featuring fully enclosed safety design, the equipment incorporates remote monitoring and intelligent control functions, meeting the highest requirements for reliability and operational safety in the nuclear industry.

For nuclear industry wastewater treatment, the typical integrated process flow works as follows: Wastewater first enters our EC electrochemical pretreatment system to effectively remove suspended particles and colloids while achieving initial pollutant enrichment and complexation breaking, creating stable conditions for subsequent deep purification. The pretreated wastewater can then be connected to special adsorption units like ion exchange to efficiently capture dissolved radioactive nuclides. The resulting high-concentration organic radioactive waste liquid (e.g., resin regeneration liquid, evaporation concentrate) subsequently undergoes critical deep treatment in the CQDHX SERIES EO electrochemical oxidation unit. Here, refractory organics are thoroughly decomposed, with chemical toxicity and COD values significantly reduced to achieve efficient volume reduction. Finally, the deeply purified effluent can be safely discharged or reused, while the minimal radioactive concentrates generated throughout the process enter solidification lines for final safe disposal.

This synergistic process, built around our EC pretreatment equipment and CQDHX SERIES EO electrochemical oxidation systems, provides a high-efficiency, waste-reduction, and intelligent solution for high-difficulty, high-risk nuclear industry wastewater treatment. Through precision manufacturing, rigorous process design, and system integration, we have transformed the theoretical potential of electrochemical technology into verifiable stable treatment performance, helping nuclear-related organizations achieve wastewater zero discharge and sustainable development strategic goals in a safer, more economical, and environmentally friendly manner.
