Simulated Co-Substrate Threshold Manifests Steady-State Amelioration of Coal Gasification Gray Water Via Synergistic Biotransformations in Continuous-Flow Anoxic-Oxic System

Опубликована: Янв. 1, 2025

This case study explored the mechanisms influencing anoxic/oxic processes in 100 ton/h treatment system of coal gasification gray water (CGGW). It was experiencing "spiked" and COD, unstable operation. To identify issues find solution, sideline simulation experiments were commenced by installing 600 times miniaturized bioreactor 14 m3 with 70 L/h inlet flow rate. Data during start-up revealed that period sludge acclimation (24 days) stabilization (10 days), 30% reflux from oxic- to anoxic-pond, 0.8-1.2 mg L‒1 DO oxic-pond favored nitrification. However, it could not sustain denitrification without adding organic carbon anoxic-pond. Therefore, two co-substrates (glucose methanol) supplemented separately metabolic response aerobic/anaerobic ammonia-oxidizing bacteria (AerAOB/AnAOB), denitrifying (DNB). Glucose increased both ponds reflecting hampered partial anammox anoxic-pond heterotrophic non-function over DNB, intolerance AOB carbon. also declined depriving AerAOB AnAOB. Methanol addition quickly enhanced denitrification; however, later declined, spiked. By reducing methanol, effluent COD met standards again. indicated overdosed methanol exceeded DNB usage, carried oxic-pond, where restricted AOB's growth On this basis, dosage main plant reduced 2400 1540 kg/day, which meet standards, achieved plant's operational stability. These findings conceptualized CGGW model "synergistic anammox-nitrification denitrification-anammox (SPANDA)" regulated lower dosage.
