Engineering Contradiction Analysis
1Object-affected harmful factors
If distillation/evaporation techniques are used to purify processed water, then radium removal is achieved, but energy consumption and cost increase significantly
Solution Approach 1:
The patent replaces mechanical/thermal purification systems (distillation, evaporation, reverse osmosis) with a chemical adsorption system using clay-based materials. The adsorbent selectively binds radium ions from processed water through chemical affinity, eliminating the need for high-energy thermal or pressure-based separation processes while achieving comparable or superior radium removal efficiency.
Solution Approach 2:
The patent modifies the chemical composition and surface properties of clay materials to optimize radium adsorption capacity. By adjusting parameters such as cation exchange capacity, surface area, pore structure, and mineralogy of the clay adsorbent, the system achieves high radium selectivity and capacity without requiring the high energy inputs needed by conventional thermal or membrane-based methods.
2Object-affected harmful factors
If membrane separation techniques are used to remove radium, then purification is achieved, but mechanical issues such as scaling, clogging, or failure occur
Solution Approach 1:
The patent replaces mechanical membrane separation systems with a chemical adsorption system using clay-based materials. The adsorbent selectively binds radium ions from processed water through chemical affinity, eliminating the need for high-energy thermal or pressure-based separation processes while achieving comparable or superior radium removal efficiency.
Solution Approach 2:
The patent employs clay-based adsorbents that can be easily replaced or regenerated. Unlike expensive membrane systems that require complex maintenance and are susceptible to fouling and failure, the adsorbent materials are inexpensive, mechanically robust, and can be简单地 filtered out or regenerated after use, ensuring continuous reliable operation without mechanical failure points.
3Object-affected harmful factors
If co-precipitation techniques are used to separate radium, then some purification is achieved, but the yield of contaminated elements is low and disposal remains difficult
Solution Approach 1:
The patent employs selective extraction of radium from processed water using clay-based adsorbents with high radium affinity. The adsorbent selectively binds radium ions from the aqueous phase, concentrating them on the solid adsorbent surface. This enables efficient separation and concentration of radium with high yield, followed by simple solid-liquid separation to recover purified water and concentrated radium-bearing waste for disposal.
