摘　　要：采用微波辐射技术,建立了双酚A生产废水的处理工艺,以颗粒活性炭为催化剂,考察了废水初始浓度,活性炭用量,微波辐射功率,微波辐射时间等对废水处理效果的影响。结果表明,25mL的废水,在微波辐射功率800W,辐射时间14min的工艺条件下,活性炭用量3g时,在废水最大吸收波长处,废水A值的去除率为94%以上,COD的去除率为90%左右。初步探讨了微波处理此废水的作用机理,并进一步研究发现在最大吸收波长处的氧化过程基本符合一级反应动力学规律。The microwave irradiation （MI） process was developed to treat the bisphenol wastewater. The granular activated carbon （GAC） was used as catalyst. The effect of the GAC amount, MI power, acting time and the initial concentration on COD removal were studied. The optimum conditions were as follows： 25 mL wastewater, microwave radiant Intensity 800 W and irradiation time 14 min. Under these conditions, when amount of GAC was 3g, the removal rates ofwastewater A and COD at the maximum adsorption wavetength were over 94% and about 90% respectively. The function mechanism of the wastewater treatment by microwave irradiation was primarily enquired into and it was discovered that the oxidation process at the maximum adsorption wavelength was basically in conformity with the first-order dynamic reaction.
