A photosynthetic algal (Chlorella vulgaris) microbial fuel cell (PAMFC) with double chambers was adopted for power production and removal of carbon and nitrogen in swine sewerage that could provide nutrients for the growth of C. vulgaris. C. vulgaris was expected to utilize carbon dioxide (CO) delivered from the anode chamber and generate oxygen as an electron acceptor by photosynthesis. PAMFC presented a maximum voltage output of 0.747 V and a maximum power density of 3720 mW/m at 240 h, much higher than that of the standalone MFC. 85.6%, 70.2%, and 93.9% removal of ammonia nitrogen, total nitrogen (TN), and total organic carbon (TOC), respectively, were obtained in the anode chamber of the PAMFC system, while the corresponding removal in MFC was 83.1%, 56.0%, and 87.2%, respectively. PAMFC also presented a much higher removal of ammonia nitrogen (68.7%) in the cathode chamber than MFC (47.5%). The results indicated the superiority of the PAMFC device for carbon and nitrogen removal.
采用具有双室的光合藻类（普通小球藻）微生物燃料电池（PAMFC）来进行发电以及去除猪污水中的碳和氮，这些碳和氮可以为普通小球藻的生长提供养分。普通小球藻有望利用来自阳极室的二氧化碳（CO）并通过光合作用生成氧气作为电子受体。在 240 小时时，PAMFC 呈现出 0.747 V 的最大电压输出和 3720 mW/m 的最大功率密度，远高于独立 MFC。PAMFC 系统阳极室分别获得了氨氮、总氮（TN）和总有机碳（TOC）的 85.6%、70.2%和 93.9%的去除率，而 MFC 的相应去除率分别为 83.1%、56.0%和 87.2%。PAMFC 在阴极室中对氨氮的去除率（68.7%）也高于 MFC（47.5%）。结果表明，PAMFC 装置在去除碳和氮方面具有优越性。
