采用双室光合藻类（Chlorella vulgaris）微生物燃料电池（PAMFC）对猪场污水进行发电和脱碳脱氮，为C.粗枝藓vulgaris被期望利用从阳极室输送的二氧化碳（CO2）并通过光合作用产生作为电子受体的氧。PAMFC在240 h时的最大输出电压为0.747 V，最大功率密度为3720 mW/m3，远高于单电池。PAMFC阳极室对氨氮、总氮和总有机碳的去除率分别为85.6%、70.2%和93.9%，MFC阳极室对氨氮、总氮和总有机碳的去除率分别为83.1%、56.0%和87.2%。PAMFC对氨氮的去除率（68.7%）也明显高于MFC（47.5%）。实验结果表明了PAMFC装置在除碳脱氮方面的优越性。
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 ofC. vulgaris.C. vulgariswas expected to utilize carbon dioxide (CO2) 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/m3at 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.
