A novel strategy employing urine wastewater derived from source separation technology, to pretreat waste activated sludge (WAS) for promoting yields of short-chain fatty acids (SCFAs), has been proposed in this study. It was found experimentally that SCFA production could ascend up 305.4 mg COD/g VSS (volatile suspended solids) with a volumetric proportion 1:2 the whole reaction system, being 8.8 times produced control. Exploration mechanism indicated WAS disintegration significantly...
Urine wastewater derived from source separation technology was employed to pretreat waste activated sludge (WAS) for anaerobic digestion in this study. In comparison the control group, cumulative methane production identified be improved by 23% after pretreated urine with its volumetric proportion of 1:8. Urea and hydrolyzed free ammonia (FA) were observed pose a synergistic effect on disintegration, benefiting reduction volume enrichment available substrates bio-processes. Analysis...
The potential of periodate (PI) in sludge anaerobic digestion is not tapped, although it has recently attracted great research interest organic contaminants removal and pathogens inactivation wastewater treatment. This the first work to demonstrate significant improvement methane generation from waste activated (WAS) with PI pretreatment provide underlying mechanisms. Biochemical tests indicated that yield enhanced 100.2 146.3 L per kg VS (VS, volatile solids) dosages 0 100 mg g TS (TS,...
Resource recovery in the form of short-chain fatty acids (SCFAs) from waste activated sludge (WAS) is usually limited due to quantity and quality SCFAs. To mitigate these restrictions, this study provides a novel method by using periodate (PI) pretreatment. With an increase PI concentration 0 50 mg/g total solids (TS), SCFA yield increased 1486 3109 mg COD/L acetic acid production was enhanced more than twice. Further had adverse effect on production. Electron spin resonance analysis...
This paper proposed a pretreatment technique for waste activated sludge (WAS) anaerobic fermentation by employing environmentally-friendly ferrous-activated-sulfite to advance the production of short-chain fatty acids (SCFAs). Experimental analysis illustrated that maximal SCFAs yield ascended 27.1 times with sulfite dosage 500 mg S/L and Fe(Ⅱ)/sulfite ratio 1.25. Mechanism explorations elucidated SO 4 · - ·OH induced Fe(Ⅱ)-activated sulfite-auto-oxidation remarkably promoted disintegration...
