Pilot-Scale Anaerobic Co-Digestion of the OFMSW: Improving Biogas Production and Startup

摘要: This paper presents experimental results regarding anaerobic co-digestion of the organic fraction municipal solid waste and fruit vegetable in order to establish efficiency a 2 m 3 volume pilot plant terms biogas methane yield stability process. The research study feasibility developing digestion as an effective method for management. experiments were conducted mesophilic conditions (35 °C). Domestic water was used inoculum. showed that inoculum presence, temperature, pH control, essential improve production its composition. Using liquid inoculum, CH 4 percentage oscillated between 44% 51%, from 0.504 0.6 /day. Compared domestic water, animal manure increased concentration (up 63%), while daily by 26% varied 0.693 0.786 . cumulative at end 11.7 15.89 , respectively. co-digestion, startup time significantly reduced, total solids content decreased 22.7% 19.8%, volatile 37.6% 31.2%.
