【摘要】 阻燃剂生产过程中产生大量的工业废水,通过对比处理实验研究表明:电解Fenton法是处理阻燃剂生产中产生的高浓度有机废水(CODC r=17108 mg/L)的有效方法,它既利用了电氧化、电气浮作用,又利用了Fenton试剂的强氧化作用和化学絮凝作用。其处理废水的条件实验结果表明:pH=2.0~2.6;电流密度10.8~14.3 A/dm2;H2O2初始浓度27~42 mmol/L;FeSO4初始质量浓度660~990 mg/L;电解5 h。CODC r去除率达98.34%,色度去除率达74.19%。色质联用分析显示废水处理后的降解产物是无毒害的醋酸。更多还原

【Abstract】 There was a great deal of wastewater in the course of the flame retardants′production and it was difficult to be treated.By means of contrastive experiment,it was found that Fenton-electrolysis was an effective method for the degradation of the wastewater of high concentration from flame-retardants production that contains COD_Cr17108mg/L.This method utilized not only the electrolytic oxidation and electrolytic floatation,but also the strong oxidation and chemistry flocculate of Fenton reagent.Our research presented the optimal operation conditions: pH=2.0～2.6,current density 10.8～14.3 A/dm²,initial concentration of H₂O₂27～42 mmol/L and FeSO₄660～990 mg/L.After 5-hour electrolysis,the removal efficiency of COD_Cr and chroma achieved 98.34% and 74.19%,respectively.Analysis result by GC-MS showed that the main degradation product of wastewater treated by the method was hurtles acetic acid.更多还原
