Abstract

利用纳米TiO2-PASS复合絮凝剂的光催化性能,处理模拟活性艳蓝染料废水和实际印染废水,研究溶液pH值、纳米TiO2-PASS投加量、煅烧温度、光照时间、H2O2用量及废水初始浓度对脱色率的影响.结果表明,纳米TiO2-PASS复合絮凝剂对模拟废水脱色的优化处理条件为:初始pH值2,纳米TiO2-PASS复合絮凝剂用量0.25 g/500 mL,光照时间120 min,复合絮凝剂煅烧温度500℃,H2O2用量0.4 mL/500 mL.对实际印染废水的优化处理条件为:废水pH值12.0,光照时间90 min,复合絮凝剂用量0.25 g/500mL,H2O2用量0.4 mL/500 mL.
