Ultrasound-sodium percarbonate effectively promotes short-chain carboxylic acids production from sewage sludge through anaerobic fermentation

Therefore, the ultrasound (US)-sodium percarbonate (SPC) technique was proposed to effectively break the bottlenecks. Results showed the total SCCAs yield, acetate yield and particulate organics reduction respectively attained 392.8 mg COD/g VSS, 204.6 mg COD/g VSS and 47.4% under the optimal condition.

据此，本研究提出超声（US）-过碳酸钠（SPC）联用技术以有效突破现存瓶颈。结果表明，在最优工况下，总短链羧酸（SCCAs）产率、乙酸盐产率及颗粒态有机物削减率分别可达392.8 mg 化学需氧量（Chemical Oxygen Demand, COD）/g 挥发性悬浮固体（Volatile Suspended Solids, VSS）、204.6 mg COD/g VSS与47.4%。
