摘要:
为了探究橙皮精油（EO）对橙渣与剩余污泥厌氧共消化系统的毒性，通过改变共消化底物中EO含量，研究其对厌氧共消化系统比产甲烷活性的影响及毒性抑制作用。结果表明，当EO为550和750 mg/kg时，其对厌氧发酵系统具有一定的促进作用，累积产气量较对照组分别提高了16.8%和21.1%；当EO为950和1 150 mg/kg时，厌氧共消化系统分别受到轻度抑制和中度抑制，其累积产气量较对照组分别降低了39.1%和49.9%；当EO为1 350 mg/kg时，厌氧共消化系统受到严重抑制，比产甲烷活性比对照组降低了98.4%，产气量几乎为0。毒性恢复实验表明，高含量EO（1 150和1 350 mg/kg）对厌氧共消化系统的微生物产生了生理毒素，辅酶F420含量显著降低，导致系统产甲烷活性受到严重抑制。
Abstract:
In order to investigate orange residue essential oil (EO) toxicity to orange residue and excess sludge anaerobic co-digestion system, effect of EO on specific methanogenic activity and toxicity inhibition of the anaerobic co-digestion system was explored by changing EO content in the co-digestion substrate. When EO content was 550 mg/kg and 750 mg/kg in the toxicity tests, it had certain promoting effect on the anaerobic fermentation system, and the cumulative gas yield was increased by 16.8% and 21.1% compared with that of the control group. When EO content was 950 mg/kg and 1 150 mg/kg, the anaerobic co-digestion system was slightly and moderately inhibited, and its cumulative gas yield decreased by 39.1% and 49.9% compared with that of the control group, respectively. When EO content was 1 350 mg/kg, the anaerobic co-digestion system was seriously inhibited, and the specific methanogenic activity decreased by 98.4% compared with that of the control group, and the gas yield was close to zero. Toxicity recovery experiment showed that high EO content (1 150 mg/kg, 1 350 mg/kg) produced certain physiological toxins to microorganisms in the anaerobic co-digestion system and coenzyme F420 content was significantly decreased. As a result, the methanogenic activity of the system was severely inhibited.
