  • METHOD FOR PROMOTING METHANE PRODUCTION FROM SLUDGE BY ANAEROBIC DIGESTION IN HIGH AMMONIA-NITROGEN HABITAT USING BIOCHAR WITH HIGH C/N RATIO
    Publication number: 20230357066
    Abstract: The present invention discloses a method for promoting methane production by anaerobic digestion in a high ammonia-nitrogen habitat using a biochar with a high carbon-to-nitrogen (C/N) ratio. In this method, a biochar material prepared by dry distillation and carbonization is added to municipal sludge for medium-temperature anaerobic digestion treatment, which increases the efficiency of methane production from sludge by anaerobic digestion in different ammonia-nitrogen stress habitats, thereby realizing the utilization of sludge as resources.
