Laboratory Study on Activated Carbon Treatment of Phenol-Containing Waste-Water

Abstract

Phenolic compounds are highly toxic and cause serious pollution when discharged into water with industrial wastewater. Using activated carbon, we tried to find out the most efficient method to get rid of phenol in waste-water. The experiment focused on the optimization of three important parameters, the applied amount of activated carbon, time period for adsorption and PH value. The results showed: PH value in the range of 3-9, activated carbon amount used from 0.1 g to 10 g, and adsorption time for over 40 mins can efficiently contribute to a more than 90% removal rate in phenolic waste-water, and therefore meeting the level 3 emission standard issued by the government, which provided a new way of thinking for the treatment of phenol wastewater.
