Study on the Treatment of phenol-containing Wastewater by High-specific Area Activated Carbon

The adsorption effects of high-specific surface area activated carbon(HSAAC)on phenol in wastewater were discussed and the factors,such as the dosage of activated carbon, pH value, the adsorption time ,the removal rate and others, were reseasched . The results of the tests showed that the greater the dosage of HSAAC, the better the effect of the removal rate of phenol . When the dosage of HSAAC was 0.2g L~(-1) the removal rate reached above 94%. Under the acidity condition, the treatment showed a better effect. When pH was less than 6 the removal rate reached above 95%. phenol in wastewater absorbed by HSAAC mainly took place during the first 15 minutes. When HSAAC was regenerated with alkali, the regenerated rate for the first time was 93.3%, and for the second time was 86.7%. All the above show that the high-specific surface area activated carbon has excellent adsorption performance and can easily be regenerated under the suitable conditions.
