摘　　要：氧化铋作为一种光催化剂,可应用于水中有机污染物的降解,并且氧化铋可实现对太阳光的有效利用,节约水处理成本。在氧化铋降解亚甲基兰模拟废水的实验中,影响其反应效果的因素包括催化剂用量、模拟废水浓度、pH值等。通过单因素和正交实验,确定了氧化铋降解亚甲基兰反应过程中的最佳实验条件。As a photocatalyst, bismuth oxide could be applied to degrade organic pollutants in water, achieved the effective utilization of solar energy, and saved the cost of water treatment. In the degradation of methylene blue wastewater by bismuth oxide, influence factors included catalyst dosage, wastewater concentration and pH. Through single factor and orthogonal experiments, the optimal experimental conditions of degradation of methylene blue by bismuth oxide were obtained.
