Enhancing Anaerobic Digestion of High Concentrated Waste Activated Sludge Through Thermal Hydrolysis Pretreatment
Short Introductive summary
Sewage treatment faces a global challenge of excess sludge, demanding sustainable solutions. This study explores the impact of thermal hydrolysis pretreatment (THP) on concentrated waste-activated sludge (WAS). Employing varied conditions (100-220°C, 2-7% TS), analyses reveal that THP significantly enhances SCOD, VS solubilization, and methane production. Increasing THP temperatures correlate with elevated SCOD, NH4-N, PO4-P, VFAs, and decreased sludge viscosity and pH. Optimal methane production (349 L CH4/kg VS, 75.5% methane) occurs at 180°C, but higher THP temperatures pose risks. THP emerges as a promising, sustainable solution for sewage sludge treatment, addressing environmental concerns and maximizing energy potential.
