Abstract
The degradation characteristics of oily sludge in the bioreactor were studied by using Euler-multiphase flow method, in which the gas-liquid two-phase and gas-liquid-solid three-phase flow field dynamics model was established. The working characteristics of the conventional bioreactor and the proposed new bioreactor were simulated via FLUENT software respectively, and the distribution of bubble diameter and the accumulation and dispersion phenomenon of the oily sludge particles were studied. The experimental results showed that compared with the conventional bioreactor, the proposed one can significantly improve the degradation efficiency of oily sludge and greatly reduce energy consumption.
