Organic matter and nutrient removal in a combined anaerobic–aerobic fixed-bed reactor treating digestate from anaerobic biodigester
Bibliographic record
Abstract
Anaerobic digestion has become a possible approach for treating organic fraction of urban solid waste. However, the treatment of the digestate is still a matter for technological development. In this work a single anaerobic–aerobic fixed-bed reactor subjected to recirculation was used to treat the effluent from an anaerobic digester fed with organic food waste. The reactor was operated for 100 days, with hydraulic retention time of 24 h. The organic loading rate applied was 1 kg COD m −3 d −1 . The efficiency in removing nitrogen, organic matter, and phosphorus were 73%, 83%, and 23%, respectively. This reactor configuration proved to be quite promising to promote simultaneous removal of carbon, nitrogen, and phosphorus from effluents with high nitrogen and organic matter contents.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
