摘要
以几种矿粒材料为载体,采用溶胶法负载纳米二氧化钛光催化剂,通过自制的光催化反应器处理造纸中段废水,研究了不同载体材料、载体粒度大小、不同处理时间对COD的去除率的影响,还研究了颗粒材料负载的光催化剂的重复利用性能。
With several mineral particles supported photocatalysts of nano-TiO2 which made through sol-gel method, papermaking wastewater was treated in a self-made photocatalytic reactor. In the experiments, influence factors of supporting material, particle size and detention time to COD removal are studied. In addition, the repeatability of the photocatalytic materials was also studied.
