The present invention relates to a biogas production system using food waste wastewater, which is fed, dehydrated, concentrated feed mixture, drying, screening, organic byproducts mixing, drying, fermentation, crushing, screening, pelletization, cooling drying and packaging. In the feed-through system, the wastewater generated in the dehydration process is first reacted in ASBR, which is anaerobic, and then bioreactor is produced by purifying the wastewater in SBR, which is secondarily reacted. will be.;According to the present invention, biogas using food waste wastewater capable of recycling the biogas generated by properly treating wastewater generated while making fermented feed having good quality and extending the storage period of the feed and having economical and practicality Provide a production system.
