摘　　要：采用Fenton试剂氧化强化活性焦吸附对反渗透浓水进行处理,考察了活性焦种类、吸附时间、活性焦投加量、pH值、H_(2)O_(2)和FeSO_(4)·7H_(2)O投加量等因素对反渗透浓水吸附效果的影响。结果表明,采用4^(#)活性焦作为吸附剂,反渗透浓水pH 7.5,吸附时间30 min,4^(#)活性焦、H_(2)O_(2)及FeSO_(4)·7H_(2)O的投加量分别为1.0 g/L、10 mg/L及60 mg/L时,COD去除率达到最大,为70.35%。Fenton试剂氧化强化活性焦吸附应用于反渗透浓水的深度处理,可以有效提高吸附氧化的处理效果。Fenton reagent oxidation was used to enhance the adsorption of activated coke to treat reverse osmosis concentrated wastewater,and the investigation was made on the impact of adsorption effect of reverse osmosis concentrated wastewater from such factors as the type of activated coke,adsorption time,activated coke dosage,pH,H_(2)O_(2) and FeSO_(4)·7H_(2)O dosage,etc.The results showed that using 4^(#)activated coke as the adsorbent,when reverse osmosis concentrated water pH=7.5,adsorption time was 30 mins,the dosages of 4^(#)activated coke,H_(2)O_(2) and FeSO_(4)·7H_(2)O were 1.0 g/L,10 mg/L and 60 mg/L respectively,the COD removal rate could reach up to 70.35%.Activated coke adsorption enhanced via Fenton reagent oxidation was an effective advanced treatment process to treat reverse osmosis concentrated wastewater.
