| 摘 要： | 采用微波-Fenton氧化-PAFSi絮凝法处理含油废水，结果表明，200mL水样先经微波辐射6rnin，在pH=2，H2O2（30％）3．5g／L，Fe2＋ 1．3g／L的条件下氧化4h后，采用聚硅酸铝铁（Al：Fe：Si=10：2：1）和聚丙烯酰胺在pH：8时进行絮凝实验，处理后废水浊度、SS、COD、含油量和色度分别降低了99．46％、96．66％、91．94％、97．97％和95．00％，且经处理后废水的BOD5／COD由原水的0．04提高到0．53。实验还分析了含油废水的降解机理。

| Abstract: | The microwave-Fenton oxidation-flocculation method was investigated to treat the oily wastewater. In this study, 200 mL of wastewater was treated with microwave for 6 min, then oxidated 4 hours un- der the conditions of pH = 2, 3.5 g/L of H2 02 （30%） , 1.3 g/L of Fe2 ＋. Final poly aluminum silicate iron （ Fe ：AI： Si = 10： 2：1 ） and polyacrylamide were used in the floeeulation experiment （pH =8）. The results showed that the turbidity, SS, COD, oil content and chrominanee of effluent decreased by 99.46%, 96.66%, 91.94% , 97.97% and 95.00% ,respectively, the value of BODs/COD changed from 0.04 to 0.53 after treat- ment, which indicated that the water quality was improved greatly, and the treatment effect was remarkable. The degradation mechanisms of oily wastewater were also analyzed. |
