Super Heavy Oil Wastewater Treatment by Combined ME and I-BF Process-A Field Pilot Study
Bibliographic record
Abstract
A field pilot test was conducted on a macro-electrolysis/biological filter with immobilized microorganism system (ME/I-BF) in the Liaohe oilfield, China to treat super heavy oil wastewater with large amounts of dissolved recalcitrant organic compounds and low nutrients of nitrogen and phosphorus. By operating the system for 155 days (including the start-up of 28 days), the BOD/COD ratio of water increases from 0.13 to 0.22 and the COD removal rate is 47.46% after the ME treatment. Then, the COD decreases to 100 mg/L and the COD removal rate is 80.96% after I-BF treatment. When indigenous microorganisms inoculated, the effluent gets better, COD decreases to 70 mg/L and the removal rate of COD increases to 88.54%. Gas chromatography/mass spectrometry (GC/MS) indicated that the super heavy oil wastewater contains 11 organic compounds and most of them are removed after treatment. This integrated system is a useful option for the treatment of heavy oil wastewater.

How this classification was reachedexpand
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.
