A new technique for treatment of furfural wastewater by closed circuit evaporation and recycling

I, our company has a patent

II. Overview

Furfural production wastewater is a difficult organic wastewater, containing acetic acid, furfural, alcohol, aldehyde, ketone, ester, organic acid and other organic matter, PH value is 2~3, COD concentration is high, biodegradability is not good.

The technology uses saturated steam as heat source, vaporizes waste water and increases pressure through evaporation system to meet the requirements of production and use, and recovers furfural and heat in waste water to realize the recycling of furfural production waste water. The device adopts automatic program control.
