In this study, a novel electrodialysis membrane bioreactor was used for EBPR sludge treatment for energy and phosphorus resource recovery simultaneously. After 30days stable voltage outputting, the maximum power density reached 0.32W/m. Over 90% of phosphorus in EBPR sludge was released while about 50% of phosphorus was concentrated to 4mmol/L as relatively pure phosphate solution. Nitrogen could be removed from EBPR sludge by desalination and denitrification processes. This study provides an optimized way treating sludge for energy production and in situ phosphorus recovery.
本研究采用新型电渗析膜生物反应器（EDMBR）同时实现 EBPR 污泥处理和能量与磷资源回收。稳定电压输出 30 天后，最大功率密度达到 0.32W/m。超过 90%的 EBPR 污泥中的磷被释放，而约 50%的磷被浓缩至 4mmol/L，得到相对纯净的磷酸盐溶液。通过脱盐和反硝化过程，可以从 EBPR 污泥中去除氮。本研究为污泥处理提供了一种优化的方法，可用于能源生产和原位磷回收。
