The digestion efficiency of hybrid reactor according to mixture ratio of livestock wastewater and food wastes of influent

Abstract

This study was conducted to evaluate the digestion efficiency of hybrid reactor according to mixture ratio of influent. Anaerobic digester was operated from 30 to 60 day's HRT in low temperature. Influent mixed livestock wastewater and food wastes was used and the mixture ratio was 5:1, 5:2 and 5:3 (livestock wastewater:food wastes). In proportion to increase of the ratio of foodwaste, TCOD concentration was on the decrease and SCOD concentration was on the increase. The removal rate of TCOD was a range of 53∼65% in 5:3 and 63∼72% in 5:2. And the removal rate of SCOD was a range of 58∼73% in case of 5:3 and 51 ∼72% in 5:2.
