In stormwater harvesting, an effective method to avoid flooding risk and pollutant migration, the collected roofing rainwater can meet part of domestic water demand alleviate resources crisis. current work, innovative oblique membrane tank layout mode was involved in electrocoagulation coupled with a gravity-driven ceramic bioreactor (EC/GDCMBR), which suitable for distributed roof treatment facilities rural water-scarce areas. The oblique-EC/GDCMBR system could improve biofilm formation porosity realize reuse. Compared traditional lateral-EC/GDCMBR during long-term operation 82 days, not only presented improved permeation flux ∼40 LMH compared that (∼34 LMH), but also exhibited lower irreversible fouling resistance (oblique: 1.68 × 109 m–1 vs. lateral: 2.02 m–1). Moreover, characteristics were determined evaluate oblique-EC/GDCMBR. Confocal laser scanning microscopy (CLSM) adenosine triphosphate (ATP) contents confirmed higher biological activity abundance Denitratisoma (∼15.38%) sludge Nitrospira (∼3.35%) explained different nitrogen removal approaches Besides, excellent purification performance standard effluent quality. word, this work presents advantage reliability sustainable treatment.

Energy-Saving Mechanism of Wastewater Treatment Process Adaptation on Natural Temperature Variation: The Case from Coking Wastewater

Environmental Science & Technology, Journal Year: 2024, Volume and Issue: 58(37), P. 16399 - 16409

Published: Sept. 5, 2024

The cyclical variations in environmental temperature generated by natural rhythms constantly impact the wastewater treatment process through aeration system. Engineering data show that fluctuations cause reactor to drop at night, resulting increased dissolved oxygen concentration and improved effluent quality. However, of variation on systems energy-saving potential has yet be fully recognized. Here, we conducted a comprehensive study, using full-scale oxic-hydrolytic denitrification-oxic (OHO) coking as case developed dynamic model integrating thermodynamics kinetics elucidate mechanisms response diurnal variations. Our study results indicate can cut energy consumption 660,980 kWh annually (up 30%) for unit OHO Wastewater facilities located regions with significant stand benefit more from this mechanism. Methods such flow control, load shifting, editing fitted into new or retrofitted engineering.
