Effects of Nickel, Cobalt, and Molybdenum on Performance of Methanogenic Fixed-Film Reactors †

摘要: The conversion of acetic acid to methane and carbon dioxide by a mixed methanogenic population from an anaerobic fixed-film digestor was stimulated the addition nickel (100 nM) cobalt (50 especially these elements in combination. Molybdenum only slightly stimulatory when added combination with both cobalt. trace metals digestors, which treat food processing waste, greatly enhanced reactor performance. Total gas productions were increased 42%, greater volumes waste could be effectively treated, residence time shortened. However, lag period for start-up not reduced. Tests showed that performance because nutrient allowed accumulation thicker fixed film.
