絮凝#x02014;微波辐射#x02014;Fenton试剂氧化法深度处理焦化废水

用絮凝#x02014;微波辐射#x02014;Fenton试剂氧化法深度处理焦化废水，研究了微波辐射时间、微波功率、FeSO₄加入量、H₂O₂加入量和废水pH对废水处理效果的影响。实验结果表明：在聚合氯化铝加入量为350mg/L、聚丙烯酰胺加入量为12mg/L、废水pH=5、FeSO₄加入量为250mg/L、H₂O₂总加入量为1400mg/L、H₂O₂分3次投加、微波功率为400W、微波辐射时间为60min的条件下，处理后出水的浊度、色度和COD去除率分别为98.59%，97.62%，86.21%。处理后出水澄清透明，COD为50.34mg/L，满足GB50050#x02014;2007《工业循环冷却水处理设计规范》的要求。

Aadvanced Treatment of Coking Wastewater by Flocculation-Microwave Irradiation-Fenton Reagent Oxidation

Coking wastewater was treated by the process of flocculation-microwave irraiation-fenton reagent oxidation. The factors affecting the treatment were studied. The experimental results show that：Under the conditions of PAC dosage 350 mg/L,PAM dosage12 mg/L,flocculated wastewater pH 5,FeSO₄ dosage 250 mg/L,total H₂O₂ dosage 1400 mg/L with 3 times of addition,microwave power 400 W and microwave irradiation time 60 min,the removal rate of turbidity,chroma and COD are 98.59%,97.62% and 86.21% respectively. The effluent is clear and colorless with 50.34 mg/L of COD,which can meet the national standards of GB 50050-2007 for industrial circulating cooling water.
