响应面法优化电芬顿预处理焦化废水研究
Optimization of Electro-Fenton Process as a Pretreatment for Coking Wastewater using Response Surface Methodology
摘要
Abstract
In order to explore the treatment effect of distilled ammonia wastewater of coking plant,the Electro-Fenton process was employed.The effects of reaction time,initial pH value and electric current density on COD removal efficiency were investigated.The Box-Behnken ex-perimental design (BBD)and response surface methodology (RSM)were used to design and opti-mize the performance of electro-Fenton process.The regression quadratic model describing COD removal efficiency of electro-Fenton process was developed and validated by the analysis of vari-ances (ANOVA).The significance levels of linear and interaction effects of the reaction parame-ters on processes efficiencies were obtained.The results show that the highest COD removal effi-ciency of 70.02% and the value of B∶C from 0.12 to 0.41 were achieved at 2 h of reaction time, pH 2.26 and 3.17 mA/cm2 of current density.The electro-Fenton technology can effectively de-grade refractory organics and improve biodegradability of coking wastewater,which is suitable for the pretreatment process of coking wastewater.关键词
