Resources Reuse the Phenols in the Coking Wastewater by the Method of Resin Adsorption
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 50 ℃, 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.
