UV+F_e^(2+)+H_2O_2处理焦化废水中难生物降解的有机毒物的研究

Research on Treatment of Nonbiodegradable and Toxic Organic Substances in Coking Wastewater with UV+F_e^(2+)+H_2O_2

研究了Fenton 试剂(H_2O_2+Fe^(2+))在紫外光(UV)幅照下,氧化处理焦化废水中难被生物降解的有机毒物的可行性,并对反应条件进行了优化,结果表明此法对焦化废水中包括多环芳烃(PAH)的所有有机毒物都有较强的去除能力。但如何降低处理费用,有待进一步工作.

A method of oxidizing non-biodegradable and toxic organic substances in coking wastewater with Fenton reagent (H_2O_2+Fe^(2+)) in presence of ultraviolet radiation is studied.The results indicate that this method has more strong distintegrating ability to all toxic organic substances,including polycyclic aromatic hydrocarbons(PAHS). However,how to reduce the treatment costs needs further work.
