本論文對微生物燃料電池處理來自小球藻（Chlorella regularis）及藍(lán)藻（Microcystis aeruginosa）的生物質(zhì)廢棄物并同時(shí)產(chǎn)電進(jìn)行了深入地研究。這些生物質(zhì)廢棄物是唯一的電子供體,并且富集的微藻生物質(zhì)具有較好的可生物降解的蛋白質(zhì)（46%）及碳水化合物（22%）,很容易被銅綠假單胞菌降解,其BOD與COD的比值約為0.65。使用微藻生物質(zhì)為填充液的生物燃料電池產(chǎn)電密度可達(dá)0.86 W/m²,庫倫效率可達(dá)61.5%。通過增加生物質(zhì)濃度的策略,其產(chǎn)電效率能夠被進(jìn)一步提升到1.07 W/m²,化學(xué)需氧量的去除率可達(dá)65.2%。經(jīng)過比較,使用微藻生物質(zhì)作為填充液的微生物燃料電池產(chǎn)電能力與使用商品醋酸鈉作為填充液的微生物燃料電池產(chǎn)電能力比較接近。使用微藻生物質(zhì)作為填充液的微生物燃料電池具有較高的電化學(xué)特質(zhì),這都?xì)w因于陽極生物質(zhì)電解液的復(fù)雜組成成分。此微生物燃料電池具有多種陽極呼吸細(xì)菌組及豐富的微生物群落結(jié)構(gòu)。此雙室微生物燃料電池采用醋酸鹽作為共基質(zhì)以增加微生物電化學(xué)活性并降低MC-LR對陽極生物膜的毒性。與僅僅加入200 mg...
