A gas treatment system for a vehicle comprising:

• a gas charging unit, a gas exhausting unit, and a tail gas treating unit:
• wherein the gas charging unit includes a plurality of air inlets arranged on a roof and a peripheral side of the vehicle and communicating with a body of the vehicle, the plurality of air inlets also connect with an air inlet channel for charging fresh air;
• wherein the gas exhausting unit includes a gas discharge channel for discharging waste gas, and the gas discharge channel has an outlet segment arranged on an upper side thereof and extending out of a top surface of a tail end of the vehicle;
• wherein the tail gas treating unit includes a negative oxygen ion generator disposed on a lower end of the outlet segment of the gas discharge channel to treat the waste gas from the gas discharge channel;
• wherein the roof includes a water isolation plate formed in an inverted V shape so as to stop rainwater flowing into the vehicle and to facilitate heat dissipation;
• wherein the outlet segment of the gas discharge channel has a rainwater shield rotatably connected thereon;
• and
• wherein the negative oxygen ion generator of the tail gas treating unit has a collection tray disposed on the tail end of the vehicle by using a support mount and located below the outlet segment of the gas discharge channel, such that the negative oxygen ion generator sprays negative oxygen ion to neutralize the waste gas.
