Although the ozone in the stratosphere has the functions of absorbing ultraviolet rays and protecting the human body, the ozone on the near ground has certain damage to the respiratory tract and cardiovascular health of the human body and also has adverse effects on the protection of crops and classical cultural relics. Near-surface ozone is mainly a product of photochemical reaction between nitrogen oxide and organic volatile matters which are artificially discharged, so that the discharge of primary pollutants of nitrogen oxide and organic volatile matters is fundamentally reduced, but under the current discharge of nitrogen oxide and organic volatile matters, when the ozone content exceeds a limit value, measures are required to be manually taken to reduce ozone pollution. However, unlike indoor air purification, there are many devices and means, and outdoor air purification devices are currently directed mainly to PM2.5 pollutant particles, and less to ozone. The invention patent application CN108310969A discloses an outdoor air purification module and purification method, wherein nitrogen oxides, organic volatile matters and ozone are removed simultaneously by a catalyst, but the catalyst has a certain service life and higher cost, and the catalytic reaction requires a certain time, i.e. the treatment capacity per unit time is limited, so that the gas flow cannot be too fast, and only 500 plus 3000 cubic meters per hour of fan can be used, which cannot well meet the requirement of outdoor large-scale air purification. How to avoid using catalyst and increase the treatment capacity is the problem that needs to be solved by the outdoor air purification device.
