Abstract

Abstract

This paper used coagulation-SBR process to treat biogas slurry generated from fermentation of sludge，and investigated the denitrification effects and conditions of coagulation-SBR process． The results indicated that when C/N of inflow was 1. 5，aeration time was 8 h，and additional C/N of denitrification was 0. 25 in SBR，the total nitrogen removal rates could reach 78. 8%． Moreover，after coagulation-SBR process，the total nitrogen removal rates of biogas slurry was greater than 80% and the total nitrogen value of effluent was less than 100mg /L． In addition，after coagulation-SBR process，the effluent of biogas slurry could be reused and applied in the preparation of fermentation liquor．
