研究目的
To evaluate the kinetics of biomethane production and the influence parameters on mono-cardboard digestion, including optimized feeding TS, F/M ratios, substrate particles, process operation, temperature shocks, and the C/N ratio.
研究成果
Mono-cardboard digestion is feasible for biomethane production with optimized conditions (F/M ratio of 0.5, particle size of 2-5 mm, and TS below 10%). Kinetic models and EEM-PARAFAC analysis effectively described the digestion process and identified key parameters influencing methane production. The study provides insights for optimizing mono-cardboard waste treatment and energy recovery.
研究不足
The study is limited to batch tests under controlled conditions, which may not fully represent continuous or large-scale anaerobic digestion processes. The impact of microbial community dynamics on digestion performance was not deeply explored.
1：Experimental Design and Method Selection:
Batch tests were conducted with mono-cardboard waste under different conditions (F/M ratios, particle sizes, TS, temperature, and C/N ratios) to investigate biomethane production. The modified Gompertz model and the modified Aiba model were used for kinetic analysis.
2：Sample Selection and Data Sources:
Cardboard waste and anaerobic inoculum from a UASB reactor were used. Characteristics of the materials were analyzed.
3：List of Experimental Equipment and Materials:
Batch vials, NaHCO3 buffer solution, pure nitrogen gas, syringe for biogas measurement, saturated NaOH solution for CO2 capture, F-4600 spectrophotometer for EEM analysis.
4：Experimental Procedures and Operational Workflow:
Batch tests were performed at 35 ± 2 °C with shaking at 120 rpm. Biogas production was measured and converted to standard conditions. EEM spectra were measured for DOM analysis.
5：Data Analysis Methods:
Kinetic models were applied to simulate biogas and biomethane production. EEM-PARAFAC analysis was used to evaluate DOM composition and variation.
