发酵浓度对餐厨垃圾厌氧消化特性的影响
|
摘要
文章在中温条件下,采用批式试验研究了不同发酵浓度(4,6,8和10gVS·L-1)对餐厨垃圾中温厌氧消化过程中甲烷日产气量、累积产气量及发酵液中pH值、氨氮、碳酸氢盐碱度和总有机酸的变化规律。实验结果表明,发酵浓度为4gVS·L-1时,餐厨垃圾的累积甲烷产量最高,为547.1mL·g-1V Sadded;发酵液中总有机酸和碳酸氢盐碱度(VFA/TIC)均小于0.4,维持了较强的缓冲能力。动力学模型参数表明,发酵浓度越高,餐厨垃圾厌氧消化启动阶段的延滞期越长,发酵浓度为10gVS·L-1时的延滞期比4gVS·L-1时的延滞期延长了1.5d。
This paper evaluated the effect of 4 different fermentation concentrations( 4,6,8 and 10 g VS·L- 1) on the anaerobic digestion( AD) characteristics of food waste under mesophilic conditions in batch tests. Parameters including the daily methane production,cumulative methane production,p H,ammonia nitrogen( NH+4-N),total inorganic carbon( TIC) and total volatile fatty acids( VFA) were determined. The results showed that the fermentation concentration of 4gVS·L- 1had the maximum cumulative methane yield of 547. 1 m L·g- 1VSadded. The ratios of VFA / TIC of fermenting slurry were less than 0. 4,maintained a strong buffer capacity. In addition,the kinetic model showed that the lag time( λ)was enlarged with high fermentation concentration,the λ of 4 gVS·L- 1concentration was 1. 5 days,shorter than that of 10 g VS·L- 1concentratiom.
