摘要:
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 40mL/h, and the mono-column wastewater treatment capacity is 300mL per batch. Under the condition of 50C, 10mL8% NaOH +10mL4% NaOH+20mLwater is selected as the desorption reagent, and the flux is 10mL/h. After the treatment process, the concentrations of volatile phenol and COD decrease from about 1 380mg/L to 12mg/L, and 15 500mg/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. ©2009 IEEE.
