  • Patent number: 11383996
    Abstract: The present invention discloses an oil-contained wastewater treatment apparatus applying the integrative physical methods. The wastewater treatment system of the invention may include a main tank, where the upper part is a rectangular body and the lower part is designed to a multi-bucket bottom structure. Two oil collection boxes are arranged to both outside ends of tank. A mud discharging outlet is attached to the bottom of the tank. Meanwhile, both of a water outlet and an electric polarizer are localized at the end face of the effluent on the tank. A power supply for the electro-adsorber is fixed to the inlet end on the top face of the tank. Divided by upper and lower deflectors, the inside of the tank is divided to three processing units, i.e., sludge-water separation unit, degradation-coalescence treatment unit, and sedimentation-electric polarization unit. Vortex centripetal gas flotation is applied to remove oil. Electro-adsorption induces the micelle clustering to achieve the decolorization.
