Method of producing biogas and compost

摘要: In the mesophile production of biogas, temperature liquid used during anaerobic, methanogenic, fermentation is raised to required (about 35° C.) by aerobically prefermenting solid substrate at substantially ambient and appropriate moisture content raise its a greater than that for fermentation. Thereafter flooding fermenting with increase heat exchange, then removing storing it in insulated environment reduce suitable degree. The above steps aerobic are repeated until has reached temperature, leaving situ enable anaerobic methanogenic take place. so doing supply external initial warming up may be dispensed with, thereby improving efficiency method.
