摘　　要：研究了Fenton预氧化对再生水混凝处理的助凝效果。结果表明:Fenton预氧化可以明显提高CODCr,浊度,PO43-,色度,UV254的去除率。经过Fenton预氧化再进行混凝处理,当聚合氯化铝(PAC)投加量为24 mg/L时各指标的去除率,相当于41 mg/L PAC单独作用下的处理效果,助凝效果明显;达到相同的处理效果,可以节省40%以上的PAC投加量,大大节约经济成本,具有推广的前景。The Coagulation-supporting effect of the pre-oxidation by Fenton reagent in the treatment of regenerate resource water was carried out. The results showed that： the removal effieiencies of CODcr, turbidity, PO43-, chroma, UV254 increased obviously compared with the common coagulation treatment. When the dosage of PAC was 24mg/L, the quality of the discharged water by the Pre-Oxidation-Coagulation-Sedimentation process was the same to that resulted from the use of 41mg/L of PAC alone, and the Coagulation-supporting effect was evident. To obtain the same treatment effect more than 40% PAC dosage was saved, so the cost of the process decreased greatly and the process can be widely used.
