Experimental Study of Anaerobic Digester Biogas Method Using Leachate from Landfill Municipal Waste

摘要

Leachate is a byproduct of landfill bioreactor system which is the process of generating biogas from municipal solid waste. Generally, the quality of leachate is lower and needs an examination to reduce the content of harmful substances that can pollute the environment. Us ually leachate is collected in large pools and are not allowed to be discharged into the rivers before being processed. This research attempts leachate as a starter in the formation of biogas from organic waste by anaerobic digester method with fermentation process. After the fermentation process, the produced gases saved into plastic bag. Furthermore, these experiments measure the concentration of methane contained in the produced gas. The experimental results showed methane that produced by leachate digester reached 42.33%. It is slightly lower than the methane that produced by goat manure, methane content 49%, and cow dung, methane content 45%.
