餐厨垃圾和市政污泥联合高温厌氧消化产沼气研究
Research on Biogas Production by Kitchen Waste and Municipal Sludge Thermophilic Digestion
摘要
Abstract
To explore the feasibility of kitchen waste and municipal sludge combined thermophilic digestion, this study simulated the actual running conditions in a 50m3 CSTR reactor. Results showed that, under the conditions of hydraulic retention time (HRT) above 20 days and the ratio of restaurant waste and municipal sludge was 4∶ 1, the biogas production and methane concentration increased by 34. 2% and 8. 1%, respectively, than that of kitchen waste digestion only. The concentration of hydrogen sulphide decreased by 65%. The restaurant waste and municipal sludge co-anaerobic digestion not only improves processing capacity and stability but also increases the output and quality of the biogas, which is a new way for the coordinated treatment of different organic wastes.关键词
