In this study, we took advantage of a ultrasound technology, which has been gradually applied in environment industry nowadays, drew sewage sludge dissolution optimization through ultrasound to improve sewage sludge disintegration much better, and maximized alternative carbon source production required at denitrification process improvement of occurrence acidogenic fermentation. A series of bench-scale, semi-continuous acidogenic fermentation experiments, using sonicated sludge as a substrate, has been conducted to investigate the effects of ultrasound methods and HRT control on acidogenic fermentation. We could see the readily biodegradable COD from acidogenic fermentation after ultrasound considerably increase comparing with each control plot. Specifically, the increase was shown more than by 50%, 40% each. For the results of respirometry measurements used to estimate availability as substrate for microbial energy production activity, we figured out that content of readily biodegradable COD easily separable increased after sonication. Because the VFAs is created abundantly at anaerobic digestion step after ultrasound of sludge rather than before pretreatment, it could be replaced as alternative carbon source, which means an enormous amount of money saved.
