纳米TiO_2光催化处理乙烯工业废水的研究

Study of Photocatalytic Degradation from Ethylene Industrial Wastewater by Using Nanometer TiO_2

以纳米二氧化钛作为光催化剂,对乙烯工业废水进行降解实验研究,考察了常温下催化剂的用量、光照时间及pH值等因素对工业废水处理效果的影响,筛选出最佳的光催化处理工艺条件。在最佳处理工艺条件下,COD和氨氮的降解率分别达到94.1%和84.5%。

This paper studied the treatment of ethylene industrial waste water with the catalyst of nanometer TiO2 by inspecting that catalyst usage in the room temperature, illumination time and pH value effects. The best processing conditions of photocatalytic techniques were identified. The degradation rate of COD and ammoniac nitrogen reached 94.1% and 84.5%, respectively.
