摘要:
This study proposed a novel pretreatment technology by combining thermal hydrolysis (TH) with calcium hypochlorite (CH) to promote sludge anaerobic digestion (AD) performance. Experimental results indicated that the optimum pretreatment condition was TH at 70 °C combined with 0.08 g/g volatile suspended solids (VSS) of CH, by which the methane production of 260.1 mL/g VSS was achieved, 59.1 % higher than control group. Kinetic analysis revealed that methane production potential enhanced from 158.9 to 257.0 mL/g VSS after TH + CH pretreatment, ...
