3-7-4 メタン発酵による高油分有機性廃棄物からのエネルギー回収

抄録

We commercialize a system for on-site methane fermentation of food waste and kitchen wastewater generated in the building, but currently we are removing the oil upstream of the fermenter to prevent methane fermentation inhibition by the oil. From the past operation results, it has been confirmed that methane fermentation operates stably if the ratio of oil content to volatile solid content is below a certain level. Therefore, we examined the confirmation of oil processing capacity by continuous test and n-Hex / VS control by volatile solid supply from the outside of the system.
