摘要:
For existing advantages in resource recovery and cost, anaerobic digestion (AD) is considered a proper technology to treat sludge. The insufficient efficiency of sludge AD however prevents its further application. This work reported a hybrid method by combining calcium hypochlorite (CH) with ultrasound (US) for sludge pretreatment to enhance the AD performance. Experimental data demonstrated that the optimal parameters of this co-treatment were CH at 0.08 g/g volatile suspended solids (VSS) coupled with US intensity of 1.0 W/mL, and relevant biomethane yield was 263.4 mL/g VSS, 15.2%, 23.1% an...
