Abstract:
Fenton oxidation process has been used for treating pulp and papermaking wastewater， which was treated by anaerobic and aerobic processes. Based on the orthogonal test and single factor test， the effects of every main factor on CODCr removal rate are investigated. Thus the optimal conditions are determined. The results show that the wastewater CODCr reaches 85.49% and the effluent CODCr is below 61 mg/L， when the influent CODCr is 415 mg/L，pH=3， H2O2 dosage is 30 mmol/L， Fe2+ dosage is 5 mmol/L， and reaction time is 50 min.

摘要：
采用Fenton氧化法深度处理经厌氧、好氧处理后的草浆造纸废水,通过正交实验和单因素试验,研究了各主要因素对废水CODCr去除效果的影响,确定了最佳工艺条件。结果表明:在进水CODCr为415 mg/L、pH=3、H2O2投加量为30 mmol/L、Fe2+投加量为5 mmol/L、反应时间为50 min时,废水CODCr的去除率达85.49%,出水CODCr降到61 mg/L以下。
