超声催化二氧化钛深度处理染料废水

超声技术作为一种新型的氧化方法,能提高难降解有机物的降解率和增强水处理中的生物活性,在废水处理中已经发挥了一定的作用.光催化氧化降解水体中有机污染物也是近年来兴起的一项新型水处理技术,能有效地降解废水中的难降解有机物,但因其对光源要求较高等因素限制了它的使用.介绍了用超声代替紫外光源降解印染业污水的方法,探讨了降解机理,综述了其在废水处理中的研究进展,并指出今后须解决的问题和发展方向.

Treatment for Dyeing Wastewater by Using Ultrasonic Technology to Catalyze TiO2

As a new type of oxidation method, ultrasonic technology can increase the degradation rate of hardly - degraded organic pollutants, enhance biological activation and play a great role in wastewater treatment with a bright future. Photochemical catalysis technology has risen in recent years and can effectively degrade the hardly - degraded organic pollutants, but it is limited because of its high standards for light sources. So in this paper one kind of new method is introduced in which UV light is substituted by ultrasound to degrade dyeing wastewater, degradation mechanism is discussed, the research development in wastewater treatment is described and the problems to be solved in the future and development orientation are also put forward.
