Abstract: The temperature and acetic acid content of wastewater from furfural production were 95-99℃ and 1.43%-2.84%. Moreover, the chemical oxygen demand (COD), biochemical oxygen demand (BOD) and BOD/COD of raw wastewater were 10 000-20 000 mg/L, 2 500-3 000 mg/L and 0.20-0.25, respectively. The sustainable development of furfural industry was seriously restricted by the difficult biodegradation of furfural wastewater. Several newly-developed extraction agents in combination with multi-stage counter current extraction could recycle more than 90% of acetic acid in furfural wastewater and the extraction efficiency could reach 97%-99%. The calcium oxide neutralization-double effect evaporation-distillation technology has been applied to neutralize acid of wastewater. The waste heat energy was recovered and a lot of acetic acid of wastewater was also recovered efficiently to produce environmental protection type calcium magnesium acetate(CMA) snowmelt agent. This technology could greatly reduce the production cost of traditional CMA snowmelt agent and realize the zero discharge of wastewater. After high temperature fermentation, furfural production waste residue was made into the organic fertilizer, or lignin and fiber ethanol were acquired simultaneously with the production of furfural. And this also showed a good prospect of industrialization.
