城市污泥添加厨余垃圾厌氧发酵产挥发性脂肪酸的研究
Anaerobic acidogenic fermentation of wasted sewage sludge mixed with kitchen waste for production of volatile fatty acids
摘要
Abstract
In order to explore the feasibility of industrialization of acidogenic fermentation for volatile fatty acids (VFAs)production and the effects of mixed sewage sludge fermentation with kitchen waste , the VFAs production at different total solid concentration was investigated . The results revealed that VFAs accumulation was improved after addition of kitchen waste to sludge , and acids concentration reached 17.62 g/L . Comprehensive consideration of the VFAs production, the substrates degradation , acid production rate and so on . the total solid concentration at 130 g/L was suggested to be appropriate for larger scale fermentation . According to the acid production rate under different total solid concentration , the kinetic equation was obtained , ,u=0.114·S/(281.764+S) ( Ks : 281 .764 g/L ,μmax : 0.114 g/L·h) .关键词
