Abstract

Anaerobic co-digestion of fruit and vegetable wastes (FVW) and primary sewage sludge was carried out in a fed-batch reactor having a volume of 21 under ambient temperature conditions. Three different proportions (25:75, 50:50 and 75:25 in terms ofVS) of fruit and vegetable wastes and primary sewage sludge were studied for an organic loading rate (OLR) of 1.0 g VS/ l.d and with a hydraulic retention time (HRT) of 25 days. The reactor with 75% FVW and 25% sewage sludge (in terms of VS) showed better performance in terms of VS reduction and biogas yield when compared to other two proportions.

摘要

在常温条件下，在一个容积为21的分批补料反应器中进行了水果和蔬菜废弃物（FVW）与原污水污泥的厌氧共消化实验。研究了水果和蔬菜废弃物与原污水污泥三种不同比例（以挥发性固体计为25:75、50:50和75:25），有机负荷率（OLR）为1.0 g挥发性固体/升·天，水力停留时间（HRT）为25天。与其他两种比例相比，含有75%水果和蔬菜废弃物及25%污水污泥（以挥发性固体计）的反应器在挥发性固体减少和沼气产量方面表现出更好的性能。
