Experiment Research on Extraction Method by Chloroform Treatment Poly-THF Wastewater
Poly-THF production wastewater was treated by Liquid-liquid extraction method, chloroform as extraction agent. the influences of phase ratio and temperature, extraction equilibrium time on wastewater treatment effect have been studied. The results showed that, under the operating conditions of temperature of 25°C, phase ratio 1:1 and extraction equilibrium time 40 min, CODCr removal efficiency above 75% is achieved, in order to lay the foundation for subsequent treatment.
