|
摘要
紫外光催化氧化技术是一种小功耗的消解技术,联合氧化水体中的总磷和总氮。根据紫外光催化氧化机理,从紫外光的氧化时间、功率和照射距离三方面考虑,设计了紫外灯消解的试验装置。通过试验,进行了联合消解水体中总磷、总氮最佳效果的探索与研究,最终确定了紫外光消解总磷、总氮的参数,为总磷、总氮在线监测设备的研发提供了技术基础。
Ultraviolet photocatalytic oxidation technology is a low-power dissipation technology that combined oxidize total phosphorus and total nitrogen in water. According to the mechanism of ultraviolet photocatalytic oxidation, a test device of UV lamp digestion was designed from the aspects of oxidation time, power and irradiation distance. Through experiments,the exploration and research on the best effect of combined digestion of total phosphorus and total nitrogen in water was carried out, and parameters were finally determined, which provided a technical basis for the research and development of online monitoring equipment of total phosphorus and total nitrogen.
