Design and Operation of VT Deep Shaft Aeration Process in Wastewater Treatment Plant in Xingping
Bibliographic record
Abstract
The VERTREATTM(VT) deep shaft aeration process was introduced by Xingping WWTP from Canada as its wastewater treatment process,firstly in China.The design capacity of this plant is 5×104 m3/d.The design effluent quality meets the second level criteria specified in Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant(GB 18918-2002).However,the first level B criteria are met in practice.The main body of VT consists of two shafts with diameter of 3.2 m and depth of 92 m.The area occupied by VT system is 4 400 m2.The oxygen transfer efficiency reaches 65% to 86%.The aeration has many purposes: it can meet the requirements of microbial metabolism,mixing,air lifting,flotation for separation of sludge and so on.Therefore,the operation cost is significantly saved.The power consumption is 0.8 kW·h/kgBOD5.

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.
