According to statistics, 44050 bacteria exist in each cubic meter of air on the road, and only 24480 bacteria exist after greening. The bacterial content of the greening area is different due to different types of trees, for example, only 589 trees are in pine forest, 744 trees are in cypress forest, 1218 bacteria are in camphor tree forest, the bacterial content in each cubic meter of air of downtown area is at least 7 times higher than that of greening area, and the bacterial content in each cubic meter of air of downtown area is ten thousand times higher than that of greening area.
In order to solve the problems, a plurality of solutions are implemented, such as chemical agent spraying, wherein chemical agents, such as hydrogen peroxide and hypochlorous acid, are mainly used, but the chemical agents have strong oxidizability, and if the chemical agents are used for killing in a pure liquid spraying mode, secondary pollution is caused, and even the health of a human body is affected in a serious case. Ozone as a gas oxidant has extremely high spectrum sterilization and odor removal performance, and in addition, ozone has certain natural decomposability, so that the harm is small after the ozone is used. However, the decomposition rate of ozone is not sufficient for certain environments with high bacteria content.

However, how to combine ozone and catalyst into a compact device suitable for air sterilization and odor removal and object surface sterilization is to be solved.
In order to solve the problems, an integrated sterilization and odor removal device is urgently needed.
