实际水体中氧氟沙星的紫外降解动力学
|
摘要
研究了紫外光照条件下氧氟沙星(OFL)在水库原水、净水厂和污水厂出水中的降解作用。结果表明,紫外光照条件下,在多种实际水体中,OFL均能发生降解。并且,降解过程均符合一级动力学方程。与超纯水相比,在净水厂出水中OFL降解最快,在污水厂出水中OFL降解最慢。
This paper studied the degradation of ofloxacin(OFL)in the effluent of reservoir raw water,water purification plant and sewage plant under ultraviolet light.The results show that under UV light conditions,OFL can degrade in a variety of actual water bodies.Moreover,the above degradation processes all conform to the first-order kinetic equation.Compared with ultrapure water,the OFL degradation is the fastest in the effluent of the water purification plant,and the OFL degradation is the slowest in the effluent of the sewage plant.
