A method and system for disposal of furfural wastewater, wherein raw crop material is transported into a hydrolysis reactor after crushed and mixed with acid to be hydrolyzed to form raw furfural liquid, and then said raw furfural liquid is transported into a distillation column to be distilled, during which furfural wastewater is discharged from said distillation column. Firstly said furfural wastewater is transported into a wastewater evaporation system to be heated it into wastewater vapor which is then transported back into said hydrolysis reactor to form recycle of said furfural wastewater. Wastewater vapor residues generated therein can be utilized directly to combust in boiler, mix with acid, or prepare end product acetate. The system for disposal of furfural wastewater comprises at least a wastewater evaporation system connecting with a heat resource which is one of steam, electricity, coal, oil, gas, plant straws or wastewater vapor residues. The present invention further provides a method and system for furfural production utilizing said method and system for disposing the wastewater. The present invention realizes furfural production with no pollution.
