摘要

Anaerobic digestion (AD) of Enteromorpha and chicken manure (CM) was conducted in triplicate to determine the biogas production rates of algae for 25 d, with a constant total VS content (10g for each bottle) and Enteromorpha/CM ratios (0∶10, 2∶8, 3∶7, 5∶5, 7∶3, 8∶2, 10∶0,blank) at 35℃.The objective of this wok was to determine the feasibility of co-digestion of Enteromorpha and CM, and optimum Enteromorpha/CM proportion on methane production and macronutrient degradation in laboratory scale.Results showed that the co-digestion of Enteromorpha and CM led to the highest CH4 production of 35.48 mL/g VS at the ratio of 7∶3,demonstrating 185 times improvement comparing with that fiom the solo-digestion of Enteromorpha.But it deteriorated as the ratio increased due to the increased ammonia inhibition.The concentration of total nitrogen (TN), total phosphorus (TP), volatile fatty acids(VFAs) and pH values showed no significant difference.However, removal rate of total organic carbon (TOC) in co-digestion was much higher than that of solo-digestion, indicating that codigestion of Enteromorpha and CM was a promising technology for both waste treatment and clean energy production.
