الوصف: BACKGROUND: Specific energy dissipation rate (ϕ) is an important performance parameter of the super-high-rate anaerobic bioreactor (SAB) and is closely linked with power matching and operation optimization. The ϕ value was investigated for a SAB using anaerobic granular sludge and simulating gas production. The ϕ models for separation, reaction and water distribution units were established. RESULTS: Experimental results showed that the model predictions agreed well with the experimental data and, thus, they may be used for power matching and operation optimization of similar high-rate anaerobic bioreactors. The ϕ value for the separation unit was so low as to be neglected. The maximum ϕ values for the reaction unit during nonfluidization, granular sludge agglomeration, liquid-solid two-phase fluidization and gas-liquid-solid three-phase fluidization states were 0.143 W m−3, 4.449 W m−3, 2.173 W m−3 and 11.132 W m−3, respectively. The maximum ϕ value for the water distribution unit was 8.37 W m−3. ϕ for the reaction unit was significantly influenced by ρp, ul and Vp, ug and dp. CONCLUSION: The maximum ϕ value of 11.132 W m−3 was the basic parameter for power matching for the SAB. Some measures were introduced to reduce the ϕ values based on parametric sensitivity analyses. The present investigation will further assist in optimizing the operation and design of SABs. Copyright © 2011 Society of Chemical Industry
