AI Technical Summary
Existing technologies for treating non-radioactive wastewater from nuclear power plants are inefficient, particularly in removing ammonia nitrogen, COD, and total phosphorus. Furthermore, electrolysis methods present risks such as unstable sodium hypochlorite content and safety hazards.
By employing precise control of sodium hypochlorite and calcium chloride solutions, combined with chemical precipitation and multi-media filtration technology, the simultaneous and efficient removal of ammonia nitrogen, COD, and total phosphorus is achieved through an automated control system. High-purity sodium hypochlorite solution is purchased externally to replace the electrolysis method, the pH of the reaction mixture is controlled, and solid-liquid separation is performed through a multi-media filter.
It achieves simultaneous and efficient removal of ammonia nitrogen, COD and total phosphorus from non-radioactive wastewater, improves treatment efficiency, avoids the instability and safety hazards of electrolysis, and meets stricter environmental standards.
