چکیده انگلیسی


- Laying hens manure and spent poppy straw co-digested successfully.
- If TAN (total ammonium nitrogen) is below 4000 mg l−1, CH4 yield above 0.36 l/g VS is achieved.
- A stepwise increase in TAN results in acclimation of microbial consortia.
- CH4 yield of 0.28 l/g VS is obtained up to 6100 mg l−1 of TAN.
- When TAN exceeds 6500 mg l−1, CH4 yield decreases below 0.14 l/g VS.

Co-digestion of chicken manure (laying hens) and spent poppy straw was investigated in a daily fed laboratory scale mesophilic anaerobic digester. The digester was operated for 240 days and the methane yield was monitored by increasing the organic loading rate (OLR) from 2.78 to 3.56 g VS l−1d−1 and the total ammonia nitrogen (TAN) up to 6650 mg l−1. The highest methane yield of 0.36 l g VS−1 was obtained when the TAN and free ammonia nitrogen (FAN) concentrations were below 4000 and 300 mg l−1, respectively. The results showed that microbial consortia were acclimated to high ammonia concentrations and a methane yield of about 0.28 l g VS−1 was achieved up to 6100 mg l−1of TAN. When the TAN concentration in the digester increased above 6500 mg l−1, the methane yield sharply decreased below 0.14 l g VS−1.
