摘要

采用电解Fenton法处理阻燃剂生产中产生的高浓度有机废水(CODCr=17108mg/L),其适宜操作条件是:pH=2.0~2.6;电流密度10.8~14.3A/dm2;H2O2起始浓度27~42mmol/L;FeSO4起始质量浓度660~990mg/L;;电解5h。CODCr综合去除率达98.34%,试剂、能量综合利用率136.1%,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。色质联用分析显示废水处理后的降解产物主要是无毒害的醋酸。

Abstract

The highly concentrated organic wastewater of flame retardants is treated by electro-Fenton method(CODCr = 17 108 mg/L). The optimal operat ion conditions include the following factors, pH=2.0~2.6, the current density is 10.8 ~ 14.3 A/dm2, the original concentration of H2O2 is 27 ~ 42 mmol/L, the original mass concentration of FeSO4 is 660 ~ 990 mg/L, the electrolyt ic time is 5 h. The CODCr removal efficiency is 98.34%,and utilization ratio of reagent and energy is 136.1%. The method not only utilizes the electrolytic oxi dation and electrolytic floatation, but also utilizes strong oxidation and chem istry flocculation function of Fenton reagent. GC - MS shows degradation produc t of wastewater which is treated by the above-mentioned method mainly is harmles s acetic acid.
