摘　　要：将线型酚醛树脂和光催化剂混合磨碎 ,经炭化、活化处理后 ,光催化剂粒子与酚醛树脂基活性炭形成光催化复合材料 ,应用于含酚废水的处理。本文探讨了光源、不同光催化剂 ,光催化剂与酚醛树脂的配比等等因素对处理含酚废水的影响。实验结果表明 :在紫外线照射下 ,该材料显示出比较好的光催化含酚废水的能力 ,并且利用光照—水洗再生法能使光催化复合材料重复使用。After the mixing and milling of linear Phenolic Resin and Photocatalyst, carbonizing and activating treatment, photocatalyst particle and phenolic resin based acticarbon turn into composite photocatalyst, which can be used for the treatment of wastewater containing phenol. This paper explores how illuminants, different photocatalysts, and the proportioning of photocatalyst and phenolic resin affect the effect of treatment of wastewater containing phenol. The experiment result indicates that under the irradiation of ultraviolet rays, the composite is of better capacity to treat wastewater containing phenol, and that the composite can be reused by adopting regeneration method with irradiation-washing.
