Organic waste gas treatment method and system

The invention provides an organic waste gas treatment method and an organic waste gas treatment system, which can simply and effectively collect and remove organic waste gas generated in the hot pressing process of an artificial board, and the method comprises the following steps: collecting waste gas from the head of a hot press and conveying the waste gas to a first cyclone separator through a first conveying pipeline; waste gas is collected from the tail of the hot press and conveyed to a second cyclone separator through a second conveying pipeline, the pipe diameter of the second conveying pipeline is larger than that of the first conveying pipeline, and the volume of the second cyclone separator is larger than that of the first cyclone separator; the waste gas separated by the first cyclone separator and the second cyclone separator is gathered into the gas collecting barrel from the top side of the gas collecting barrel to be mixed, then is output from the bottom side of the gas collecting barrel and is
