Multiple effect integrated waste gas purification system

The present invention discloses a new waste gas treatment system. A purpose of the present invention is to provide a treatment process for overcoming defects in the prior art and achieving a good waste gas purification effect. The system comprises an ozone and ultraviolet photocatalyst purification device, an air nanometer sphere purifier and a biological trickling device. With the system of the present invention, the decomposition on the organic waste gas can be well completed, the investment cost and the operating cost are substantially reduced, and the risk of burning generation during the active carbon desorption process is avoided. The system of the present invention is suitable for treatment of all organic waste gas having medium-low concentrations.
