The Important Intermediate Products in Anaerobic Digestion - Organic Acids
Zhao Qingliang; Wang Baozhen; G.Kugel
Organic acids are the most important intermediate products in anaerobic digestion, from which most CH4 is formed by their further reduction. Total organic acids and their spectrum in the process of two - phase thermophilic/mesophilic digestion of sewage sludge and other high strength organic wastes have been comprehensively studied in the paper. The experimental results show that the thermophilic phase is mainly for hydrolysis and acidification of organic substrates and mesophilic phase for the reduction of organic acids and the production of digestion gas.
