餐厨垃圾与固体废物共消化产气效果研究
Research on gas production of cooked garbage and solid wastes by co-digestion
摘要
Abstract
In order to study the effect of anaerobic co-digestion of kitchen waste with different solid wastes and the optimal feeding method of kitchen waste/sludge co-digestion, a self-made fully mixed anaerobic reactor was used in this study. The gas production potential of the co-digestion system was comprehensively evaluated through gas production and methane content where cooked garbage and six solid wastes mixed system (chicken manure, pig manure, corn stalk, wheat straw, rice straw and activated sludge) under different ratios. Effects of different feeding methods on the cooked garbage/sludge system were comprehensively evaluated by the performance of gas production of the system and pH, VFAs mass concentration, ammonia nitrogen mass concentration and alkalinity of the digestive juice. The results show that the potential gas production of the co-digestive system with six different substrates is activated sludge (5:5)>chicken manure (5:5)>corn stalk (3:7)>wheat straw (3:7)>rice straw (5:5)>pig manure (1:9). All indicators of the continuous feed system for food waste/activated sludge co-digestion system are superior to the sequential batch feed system. And it is more suitable for anaerobic fermentation to produce biogas.关键词
