低温等离子体协同K2Fe4O7催化净化腈纶废水
Catalytic purification of acrylic fiber wastewater by low-temperature plasma in conjunction with K2Fe4O7
摘要
Abstract
The co-catalytic treatment of acrylic fiber wastewater using low-temperature plasma generated by a dielectric barrier discharge was studied.The solid catalyst K2Fe4O7 was synthesized by hydrothermal synthesis and characterized by X-ray diffraction and scanning electron microscopy.Wastewater samples from Sinopec Anqing Branch were used as experimental water samples,and chemical oxygen demand(COD)and turbidity were used as indices.The activity of the catalyst was first verified.Thereafter,based on a single factor experiment,a response surface method was used to optimize the test based on discharge voltage,amount of catalyst addition,and pH.The optimal response parameters were obtained as a discharge voltage of 40 kV,catalyst addition amount of 0.05 g,and pH of 2.The predicted COD degradation and turbidity removal rates of the optimal acrylic fiber wastewater were 77.43%and 91.14%,respectively.To verify the accuracy of the model,three sets of experiments were conducted under the predicted optimal experimental conditions to determine the COD degradation rate of acrylic fiber wastewater as 77.34%and turbidity removal rate as 91.11%.The accuracy of the model used in this study is relatively high.This study provides a novel approach for the purification of petrochemical wastewater.关键词
