This research demonstrates improved ammonia elimination using chlorine in an advanced oxidation process, indicating effective wastewater treatment methods.
Key Points
The study aims to enhance ammonia nitrogen removal using a chlorine-assisted UV-activated persulfate system.
Utilized a UV-activated persulfate system for treating ammonia nitrogen in wastewater.
Introduced chloride ions to improve ammonia degradation efficiency.
Conducted experiments at pH 7, with specific concentrations of persulfate and chloride ions.
Measured the degradation rates and generated reactive chlorine species.
Achieved complete degradation of 30 mg/L ammonia nitrogen within 40 minutes.
Total nitrogen removal rate reached 75.50%.
Increased reaction rate constant from 0.0026 min−1 to 0.0801 min−1 with chlorine addition.
