ABSTRACT
With the increasingly severe global water resource shortages and water environmental pollution, advanced purification technologies for wastewater treatment plant effluents have become a critical pathway to achieving sustainable water resource utilization. This study aims to improve effluent quality and reduce pollutant emissions by addressing the low efficiency and high energy consumption issues of traditional treatment processes. A novel integrated deep purification technology combining advanced oxidation processes (AOPs) with bio-enhanced treatment was proposed. Through laboratory-scale experiments, pilot-scale trials, and case studies of actual engineering applications, the performance of this technology in removing recalcitrant organic compounds, nitrogen and phosphorus nutrients, as well as micropollutants was systematically evaluated. The results indicate that AOPs effectively decompose complex organic substances, while the subsequent bio-enhanced process significantly improves the removal efficiency of nitrogen and phosphorus. The synergistic effect of these two processes optimizes the overall treatment performance. Compared with conventional methods, this technology ensures stable compliance with discharge standards while reducing energy consumption by approximately 20% and decreasing chemical costs by over 15%. Additionally, an intelligent operation and control system was developed to dynamically adjust process parameters based on influent water quality, enhancing the adaptability and stability of the system. The findings demonstrate that this technology is characterized by high efficiency, cost-effectiveness, and environmental friendliness, offering a new technical solution for the advanced purification of wastewater treatment plant effluents. This research holds significant implications for promoting water environmental remediation and resource recovery.
