废弃脐橙与猪粪厌氧共消化的反应性能研究

采用自制序批式厌氧消化装置，在中温（37℃）条件下研究废弃脐橙与猪粪厌氧共消化的反应性能，通过设计正交试验，研究TS、C／N、温度对产甲烷的影响。结果表明：各处理容易在短时间内迅速积累大量的挥发性脂肪酸，在不调控pH的情况下产甲烷过程容易受到抑制。正交试验结果的直观分析表明对产气性能影响最大的因素是C／N，其次是TS，影响最小的是温度，初步得出最佳反应条件为C／N=35、TS=15％、温度55℃。...

The potential of mesophilic anaerobic digestion for the treatment of navel orange wastes and swine manure was evaluated. Co-digestion process was conducted in batch digesters. Effects of total solid （ TS ） , C/N, and temperature on co-digestion process were studied by orthogonal experiment. Results showed that high-level accumulation of volatile fatty acid （ VFAs ） and lack of pH-regulation might contribute to poor methane production. According to intuitive analysis, the most influent factor for biogas production was C/N, follow by TS, then temperature. The optimum condition was C/N of 35, TS of 15% and at 55℃.
