摘要
采用自制的序批式"厌氧发酵产氢反应装置",以餐厨垃圾为发酵底物,污水处理厂剩余污泥为接种微生物,初始pH为7.0、温度为37℃条件下,研究餐厨垃圾和剩余污泥不同质量混合比对厌氧发酵产氢的影响。结果表明,餐厨垃圾和剩余污泥质量比为4∶1时,厌氧发酵产氢效果最好,累积产氢量和单位产氢量(以VS计)最大,分别为252.2 m L和53.3 m L/g,TS和VS的去除率分别为20.9%和13.8%。
The effect of substrate/inoculum mass ratio of 4/1 on hydrogen production during anaerobic fermentation of steamed kitchen waste was investigated in a sequencing batch anaerobic fermentation reactor inoculated microbe with residual sludge from wastewater treatment plant, with initial pH of 7.0 and an inoculation temperature of 37℃. The results showed that the substrate/inoculum mass ratio was 4/1, anaerobic fermentation had the best effect of hydrogen production, and the maximum cumulative hydrogen production and unit hydrogen production(VS) were 252.2 mL and 53.3 mL/g, respectively. The removal rate of TS and VS was 20.9% and 13.8% respectively.
