摘要
印染废水的治理是水系环境治理的重点,而亚甲基蓝是印染废水中典型的有机污染物。本论文选用掺杂铁、钒、硅和锌等离子的纳米TiO2作为光催化剂对亚甲基蓝进行降解研究。焙烧温度与光催化剂掺杂量对样品光催化降解亚甲基蓝的活性具有很大影响,焙烧温度为500℃,Si4+掺入量为5%时光催化剂对亚甲基蓝的降解效果最好。
Printing and dyeing waste water treatment has become one of the key part of sewage treatment. Methylene blue is the typical organic pollutant in dyeing waste water. Methylene blue solution is degraded by nano-TiO2 doped Fe^3＋ , V^5＋ , Si^4＋ and Zn^2＋ as photocatalysts. Calcining temperature and dosages of photocatalysts affect the photocatalytic degradation rate of methylene blue greatly. The photocatalytic degradation rate of methylene blue is highest when calcining temperature is 500~C , dosage of Si^4＋ is 5%.
