A batch anaerobic test was conducted to evaluate the effects of adding high carbon content of corn straw to the digestion of Taihu blue algae to attain an optimal C/N ratio for higher methane yield. The addition of corn straw in algae at a C/N ratio of 20/1 increased methane yield by 61.69% at 325 mL g(-1)VS(-1) (compared with 201 mL g(-1) VS(-1) of algae digestion alone), followed by C/N ratios of 16/1 and 25/1, all operated at 20 g VSL(-1) and 35 °C. The results suggest the optimal C/N ratio for co-digestion of algae with corn straw is 20/1. The findings could offer options for efficient methane production and waste treatment.
进行了一批批厌氧测试，以评估在消化太湖蓝藻时添加高碳含量的玉米秸秆对达到更高甲烷产量的最佳 C/N 比的影响。在 C/N 比为 20/1 的条件下，将玉米秸秆添加到藻类中，在 325 mL g(-1)VS(-1)（与单独消化藻类的 201 mL g(-1) VS(-1)相比）下，甲烷产量增加了 61.69%，随后是 C/N 比为 16/1 和 25/1，所有操作均在 20 g VSL(-1)和 35°C 下进行。结果表明，藻类与玉米秸秆共消化的最佳 C/N 比为 20/1。这一发现为高效甲烷生产和废物处理提供了选择。
