TREATMENT OF WASTEWATER CONTAINING BENZENE BY TECHNOLOGY COMBINED BLOW-OFF WITH FENTON REAGENT OXIDATION

摘要

The influence of wastewater containing benzene from chemical industry by technology combined blow-off with Fenton reagent oxidation was experimentally studied. The present results suggest that the technology combined blow-off with Fenton reagent oxidation can effectively remove benzene pollutant in wastewater. The main factors that influence the removal benzene such as temperature and blowing time and volume, pH and reagent dosage of H202 and Fe2+ are studied and the optimal experimental conditions are as follows: time 20min, temperature 40 square, air-blowing volume 0.4L/min, pH value 5, and H202 and Fe2+ dosage 2mL/L and 200mg/L respectively. Under the above conditions, benzene pollutant can be removed up to 97 percent . Compared to other removal ways of wastewater containing benzene, the technology combined blow-off with Fenton reagent oxidation is more effective and has the advantage of high speed.
