Abstract

The invention discloses a double-tank oxidation pond for evaluating catalytic ozonation efficiency, comprising detachable tank bodies made of organic glass, movable ozone aeration pipes and sampling holes. Each tank body has three sections. The height of ozone aeration tube and the number of the holes can be adjusted. The holes are distributed at different positions of the tank bodies for real-time in-situ sampling. It is easy to observe the distribution profile of the gas, liquid and solid phases in the tank bodies. The square double-tank structure is similar to actual production process, and thus the experimental data is easy for computer simulation to enlarge to the actual production process. The size of the ozone aeration pipe and the position of holes in the tank can be adjusted to evaluate the catalytic ozonation effect of sewage treated by different aeration ways and aeration heights.
