The invention discloses an organic dye wastewater treatment system using pyrite tailings, which utilizes naturally oxidized pyrite tailings to perform photocatalytic oxidation degradation of organic dye wastewater under illumination and aeration conditions in a treatment tank, and reacts The inside of the tank is provided with a deflector with a hollowed-out center, and the mixture of pyrite tailings and wastewater is introduced into the deflector, and the mixture of pyrite tailings and wastewater flows inside the vortex wall, which not only provides The space for aeration and aeration is also extended, and the flow length of the mixture of pyrite tailings and wastewater is also extended, and the recovery tank is set up to realize the effect of on-line continuous organic dye wastewater treatment, so that the pyrite tailings can be fully utilized. . |
