文摘
- •
Thermophilic condition favors ammonia production during dry anaerobic digestion.
- •
Ammonia production has strongly negative linear relationship with manure's TS.
- •
First-order kinetic models well fit the dry ammonia fermentation process.
- •
65% of organic-N conversion was achieved under optimal 8 days' dry AD conditions.
- •
> 90% of TAN in swine manure was recovered by dry AD and stripping at 20% TS.
