ZVI combined with alkaline pretreatment optimizes FW and RS anaerobic co-digestion: methanogenic potential, acidification mitigation, and microbial community regulation.
Food waste and residual sludge co-digestion suffers from poor biodegradability and frequent acid inhibition, due to abundant refractory organics and dense extracellular polymers. Batch anaerobic digestion experiments were performed to explore the combined promotion effect of alkaline pretreatment combined with zero-val...
