The present invention relates to an integrated treatment device for exhaust gas containing dust. The integrated treatment device comprises a purification body, two ends of the purification body are provided with an inlet and an outlet, the inside of the purification body is provided with a dust removal device, an inlet flow equalizing net, a low-temperature plasma electric field, an ultraviolet lamp tube and an outlet flow equalizing net along the direction from the inlet to the outlet in turn; the dust removal device comprises a coarse filtering device, a bag dust removing device and a dust discharging hopper; the coarse filtering device is located in front of the bag dust removing device, and the dust discharging hopper is arranged below the coarse filtering device and the bag dust removing device. The integrated treatment device can remove most of dust particles in the exhaust gas by passing the exhaust gas containing many dust particles through the coarse filtering device and the bag dust removing device, may not cause blocking of subsequent processing equipment and covering of the lamp tube, the long-term operation of the equipment can be ensured, and the integrated treatmentdevice can reduce floor space and is easy to install.
