摘    要:探讨了TiO2光催化技术处理纸厂废水时的影响因素,并由此确定出较优的反应条件为催化剂选择20%金红石和80%锐钛矿组成的混晶型TiO2,催化剂用量1g/L,曝气采用纯氧曝气,O2流速为0.5L/min。在此条件下,研究了制浆造纸废水TiO2光催化降解效果;结果表明TMP废水、纸厂废水等低浓低污染物废水比KP废水更适宜于TiO2光催化降解处理。

关 键 词:TiO_2光催化技术  制浆造纸废水  降解处理

Abstract:The were influencing factors about the application of photocatalysis on TiO_2 for degrading pulp and papermaking wastewaters discussed. And the optimum reaction conditions were made as follows: TiO_2 made of 80%anatase and 20% rutile was used, its concentration 1g/L, the purge gas was pure oxygen, and its flow rate 0.5L/min. Under these conditions, the degrading effects of various pulp and paper making wastewaters with photocatalysis on TiO_2 were also studied.The results indicated that effluents from TMP mill and paper mill were more feasible than KP mill effluent when treated in this method.
Keywords:photocatalysis on TiO2  pulp and paper - making wastewaters  degradation
