| 内容記述 | The sustainable management of aquaculture wastewater is crucial for environmental stewardship and resource valorization. Vacuum Membrane Distillation (VMD) was systematically investigated as an advanced process for recovering ammonia and concentrating nitrate and phosphate. Initial batch tests established optimal process conditions for selective ammonia separation and high concentration factors of non-volatile nutrients (nitrate and phosphate). Applying these conditions to prefiltered inland aquaculture wastewater, the first-stage VMD achieved >85% ammonia removal, recovering it 40-fold (from 25 mg/L to 1,015 mg/L) in a dilute phosphoric acid-receiving solution, with a separation factor of 120. Subsequently, the second-stage VMD concentrated the remaining nitrate and phosphate by approximately 5-fold within 60 h. The VMD membrane exhibited a minor 10% flux decline and maintained excellent conductivity rejection (>99%), producing high-quality permeate with 80% water recovery over 120 h of operation. The technoeconomic analysis confirmed the system's viability, showing that baseline operating costs (<USD 25/kg nitrogen recovered) in the first-stage VMD could potentially be offset by the recovered ammonia product revenue at elevated ammonium feed concentrations (>343 mg/L). Conversely, the second-stage system for nitrate-phosphate recovery was unprofitable at baseline due to the high purified water production cost (USD 162/m3). Sensitivity analysis indicated that moderate feed concentrations (>100 mg/L) combined with targeted energy and component optimization enable economic feasibility in both stages. Overall, these results provide a robust reference for recovering concentrated, multiple nutrients from aquaculture wastewater, demonstrating strong potential to achieve complete nitrogen and phosphorus recovery, zero-waste discharge, and production of valuable, high-quality liquid fertilizers for agricultural reuse. | |||||||||
