摘要： In this study, an extended Anaerobic Digestion Model No.1, which considered the degradation and inhibition properties of furfural, was established and implemented to simulate the anaerobic co-digestion of steam explosion pulping wastewater and cattle manure in batch and semi-continuous modes. Batch and semi-continuous experimental data helped calibrate the new model and recalibrate the parameters related to furfural degradation, respectively. The cross-validation results showed the batch-stage calibration model accurately predicted the methanogenic behavior of all experimental treatments (R2 >= 0.959). Meanwhile, the recalibrated model satisfactorily matched the methane production results in the stable and high furfural loading stages in the semicontinuous experiment. In addition, recalibration results revealed the semi-continuous system tolerated furfural better than the batch system. These results provide insights into the anaerobic treatments and mathematical simulations of furfural-rich substrates.
