Anaerobically digested effluent from kitchen waste (ADE-KW) was used herein as the substrate of a tubular photosynthetic microbial fuel cell (PMFC) for power production, and also, after being diluted, as a medium for cultivation of algae in the cathodic chamber. Adding 3 mg/L phosphorus to the catholyte could efficiently enhance the algal growth and the PMFC performance. About 0.94 g/L algal biomass and 0.57 kWh/m-ADE-KW bioelectricity were obtained from the PMFC. Soluble microbial byproduct-like material and aromatic proteins were the dominant organics in the ADE-KW, which were readily degradable in the system. About 79% of the 1550 mg/L ammonium in the anolyte transferred to the catholyte through the cation exchange membrane. The ammonium was removed mainly as electron acceptors at the cathode after being oxidized by oxygen, whereas algal assimilation only account for about 14.6% of the overall nitrogen.
本文以厨房废物厌氧消化液（ADE-KW）作为管状光合微生物燃料电池（PMFC）产电的底物，同时将其稀释后作为阴极室中藻类培养的培养基。向阴极液中添加 3mg/L 磷可以有效地促进藻类生长和 PMFC 性能。从 PMFC 中获得了约 0.94g/L 的藻类生物质和 0.57kWh/m-ADE-KW 生物电能。在 ADE-KW 中，可溶性微生物副产物样物质和芳香族蛋白质是主要的有机物，在系统中易于降解。阳极液中约 1550mg/L 的铵通过阳离子交换膜转移到阴极液中。铵在被氧气氧化后主要作为电子受体在阴极被去除，而藻类同化仅占总氮的约 14.6%。
