摘　　要：采用自制的三维电极反应装置净化阿司匹林(ASP)模拟废水。单因素实验系统研究了电解电压、电解时间及ASP模拟废水原液初始pH值对废水净化效果的影响规律。然后采用响应面法优化实验,在实验设计的操作条件下,软件预测最优阿司匹林废水净化工艺条件:电解电压为33.70 V,改性活性炭填充量为16.96 g,电解时间为89.89 min,原液pH为8.82,COD去除率为101.46%。为验证模型的准确性,在预估最优实验条件下进行三组实验,测定阿司匹林废水COD去除率为98.34%,此时浊度去除率为96.06%。本研究为阿司匹林这类制药废水的净化提供了一些参考和借鉴。A self-made three-dimension electrode reaction device was used to purify aspirin(ASP)simulated wastewater.The effects of electrolytic voltage,electrolytic time and ASP simulated initial pH value on wastewater purification were studied by single factor experiment system.Then,response surface method was adopted to optimize the test.Under the designed operating conditions,the software predicted the optimal operating conditions of aspirin wastewater purification process:electrolytic voltage 33.70 V,modified activated carbon filling amount 16.96 g,electrolytic time 89.89 min,pH of the original solution 8.82,COD removal rate is 101.46%.In order to verify the accuracy of the model,the COD removal rate of aspirin wastewater was 98.34%and the turbidity removal rate was 96.06%in three groups of experiments under the predicted optimal experimental conditions.This study provides some references for the purification of pharmaceutical wastewater such as aspirin.
