Study On Treatment Of Phenol Containing Wastewater By Active Carbon

Using activated carbon’s adsorption as a method for treatment of drinking water,this method can remove organic pollutants and ammonia efficiently. the water’s chemical can get effective guarantee safety,The advantages including economy and Operation management, activated carbon’s adsorption have widely adopted by developed countries for a long time. Activated carbon(AC) has been widely used as an adsorbent in waste Phenol Water is widely seen in organic wastewater. Effect factors including adsorption time, temperature, initial concentration, pH and quantity of AC were discussed in detail.The regeneration conditions were also studied to get the optimal conditions. The results showed that AC suits to absorb organic wastewater when pH is 5. The congdition that absorb organic wastewater of high concentration is that the best temperature is 20,the adsorption time is 20 min,and the quantity of AC is 7g/250 m L.In this condition, phenol can remove from 1000mg/L to 16.4mg/L. The congdition that absorb organic wastewater of middle concentration is that the best temperature is 20,the adsorption time is 40 min,and the quantity of AC is 6g/250 mL.In this condition, phenol can remove from 500mg/L to 9.2mg/L. The congdition that absorb organic wastewater of low concentration is that the best temperature is 40,the adsorption time is 50 min,and the quantity of AC is4g/250 mL.In this condition, phenol can remove from 100mg/L to 8.4mg/L.The best effect factors of activated carbon regeneration are that the rate between activated carbon and NaOH is 1:14,the initial concentration of NaOH is 3% when the temperature is 100℃ and the adsorption time is 3 hours. The regeneration rate is96.9%. The results of this study, available for reference in similar future.
