摘要
目的:在脉冲电化学氧化法处理含苯胺废水过程中,利用响应面法(RSM)下的中心复合设计法(CCD)对处理条件进行优化。方法:选取了30组代表性的试验点,以NaCl摩尔浓度、占空比、频率和电压为考察因素,苯胺去除率为响应值,设计了四因素三水平的响应面实验,并建立数学模型,研究影响脉冲电化学氧化法处理废水中苯胺的因素及其交互作用。结果:在NaCl摩尔浓度为0.1 mol/L,占空比为60%,频率为120 Hz,电压为7 V条件下,苯胺的去除率达到98.62%。结论:各因素中,NaCl质量浓度和电压之间存在显著交互作用,从而为脉冲电化学氧化法处理苯胺废水提供了实验基础。
Aims:This paper aims to optimize the treatment conditions in the process of pulsed electrochemical oxidation of aniline-containing wastewater by using the central composite design method(CCD)of the response surface method(RSM).Methods:A response surface experiment with four factors and three levels was designed;and a mathematical model was established with 30 groups of representative test sites.The investigation factors were the concentration of NaCl,duty cycle,frequency and voltage.The response value was the aniline removal rate.The factors affecting the treatment of aniline in wastewater by pulsed electrochemical oxidation and their interaction were studied.Results:The results showed that under the conditions of a NaCl concentration of 0.1 mol/L,a duty ratio of 60%,a frequency of 120 Hz and a voltage of 7 V,the removal rate of aniline reached 98.62%.Conclusions:Among the factors,there is a significant interaction between the NaCl concentration and the voltage.This study provides the experimental basis for the application of pulsed electrochemical voltages.
