Abstract :
The resin adsorption process has been developed to remove phenols from coking wastewater and its technological parameters are optimized. The results show that the ultra-cross linking adsorption resin, NDA-99, is an effective adsorbent to treat the coking waste water when its pH is 4.0 and the absorbing flux is 40 mL/h, and the mono-column wastewater treatment capacity is 300 mL per batch. Under the condition of 50degC, 10 mL 8% NaOH + 10 mL 4% NaOH + 20 mL water is selected as the desorption reagent, and the flux is WmL/h. After the treatment process, the concentrations of volatile phenol and COD decrease from about 1 380 mg/L to 12 mg/L, and 15 500 mg/L to less than 650 mg/L respectively. The raw phenol desorption solution can be recovered just as the high concentration desorption solution by isopropyl ether extraction-distillation. Thus, the resource recycle of phenol in coking wastewater is carried out.
