UV-ozone photocatalytic reaction system and degradation-resistant sewage treatment method thereof

The invention provides a UV-ozone photocatalytic reaction system which comprises a sewage tank, an ozone reduction tank and four photocatalytic reactors, the sewage tank and the four photocatalytic reactors are sequentially connected in series, and the ozone reduction tank is communicated with the sewage tank and the photocatalytic reactor at the farthest end of the sewage tank at the same time. The cylindrical appearance structure is simple and reasonable, multi-stage treatment is adopted, pollutants in sewage can be thoroughly removed, and the treatment cost can be reduced by utilizing the ozone reduction tank to recover ozone. 本发明提供了一种UV-臭氧光催化反应系统，其包括污水箱、臭氧消减罐和四个光催化反应器，所述污水箱和四个光催化反应器依次串联，所述臭氧消减罐同时与污水箱和距离污水箱最远端的光催化反应器相连通。本发明采用圆柱形外形结构简单合理，使用多级处理，能够彻底将污水中的污染物处理掉，利用臭氧消减罐回收臭氧能够降低处理成本。
