摘　　要：利用XRD、SEM对光催化颗粒材料进行结构表征,并通过絮凝-颗粒材料光催化氧化法对造纸废水进行处理,研究表明：当硫酸铝投加量为8 g/L,pH值6.5~8.5,颗粒材料用量0.12 g/mL,流经2个反应柱,光照共4 h后,COD去除率和脱色率均可达90%以上,处理后的水符合国家造纸工业水污染物排放标准（GB3544—2001）的一级标准。The mineral supported nanometer titanium granulated material was characterized by XRD and SEM.The material was used to treat paper-mill wastewater using the process of photocatalytic degradation in combination with flocculation.The results showed that under the conditions of pH 6.5～8.5,the optimal amount of Al2（SO4）3 at 8 g/L,and with the addition of granulated nanometer-material of 0.12 g/mL,a ultraviolet reaction time of 4 hours,both the rate of removal of chroma and COD achieved more than 90%.If add another column with new granulated materials,the quality indexes of the wastewater after only half an hour＇s reaction conformed to the first level of paper-mill wastewater discharge standard（GB3544—2001）.
