GC—MS法分析Fenton法处理焦化废水难降解有机物规律
The degradation rule of the refractory organics in coking wastewater by the GC-MS analysis method
摘要
Abstract
The reciprocal effects of initial pH, H2 O2 dosage, [H2O2 ]/[Fez＋] molar ratio and reaction time on the coking wastewater treatment by Fenton＇s reagent were investigated by the response surface analy- sis methods （RSM） of Box-Behnken Design （BBD）. The simulation results by quadratic response surface model showed that the interaction influence of [Fe2＋]/[H2O2-] （molar ratio） and H2O2 dosage are the most significant factors. The percent COD removal of the raw wastewater, the effluent of aerobic tank and secondary sedimentation tank are 44.60%, 47. 30%, 56.59%, respectively under optimal conditions that pH of 3.60,m（H2O2）/m（CODcr） of 1.95, [Fe2＋]/[H202] of 1/7.43 and reaction time of 30.8 min. A great amount of · OH radicals produced due to Fenton＇s oxidation by the analysis GC-MS method attacked the C-C bond on the benzene ring of volatile phenol and nitrogen heterocyclic compounds pollutants in coking wastewater. The degradation products were mainly petroleum hydrocarbon-based and some of the esters, alcohols, etc. The results indicated the volatile phenols could be removed significantly by aerobic process and the Fenton method.关键词
