The invention relates to a comprehensive treatment apparatus for fog and haze in industrial areas, comprising: a chimney type thermal power generator (1), fog and haze collecting pieces (2), convex adsorption devices (3), a solar panel (4), an air-exhausting treatment system (5), a cable (6), a sewage processor (7), and a water collector (8). The chimney type thermal power generator (1) is used togenerate electricity, and the generated electric energy is distributed to all fog and haze treatment apparatuses in an industrial park through the cable (6). The fog and haze collecting pieces (2) onthe fog and haze treatment apparatus are opened during operation, and the contact surfaces of the fog and haze collecting pieces (2) are provided with the convex adsorption devices (3), so that fullcontact with the fog and haze particles is achieved, and the air-exhausting treatment system (5) is combined for treatment. Then purified air is discharged to accelerate air circulation, harmful gasesand particles in air are filtered, and collected pollutants enter the sewage processor (7) through the water collector (8) to filter out harmful particles, and finally the effect of purifying the airis achieved.
