Abstract

Graphical abstract: Highlights: TAP pretreatment significantly increased cumulative CO2 and NH3 emissions. TAP pretreatment decreased cumulative CH4 and N2 O emissions. The maturity of SFR compost promoted by TAP pretreatment. The enrichment of maturity attributed to the increase of HA and NO3 – . Abstract: Aerobic composting combined with appropriate pretreatment is promising to achieve the utilization of antibiotics fermentation residues (AFRs). This research studied the effect of thermally activated peroxodisulfate (TAP) pretreatment on greenhouse gas (GHGs) emission, dissolved organic matter (DOM) and maturity evaluation during spiramycin fermentation residue (SFR) composting. Three treatments were conducted from co-composting of SFR and wheat straw, while 90% and 99.9% residual spirmycin removal pretreatment SFR by TAP were provided and compared with raw SFR. The cumulative CO2 and NH3 emissions increased by 17.2% and 30.8% after TAP pretreatment removed 99.9% residual spiramycin in SFR, while the cumulative CH4 and N2 O emission decreased by 34.0% and 5.27%, respectively. The DOM, humic acid (HA)/fulvic acid (FA) and NH4 + /NO3 – analysis confirmed that the composting maturity was improved with the increasing of HA and NO3 – content by TAP pretreatment.
