Embodiment Construction

[0039] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.

[0040] Such as figure 1 As shown, a complex oily wastewater treatment method and device of the present invention include a wastewater enhanced air flotation tank 1, an ozone oxidation air flotation tank 2, a modified magnetic seed adsorption coagulation sedimentation tank 3, and an activated carbon adsorption tank 4.

[0041] The waste water enhanced air flotation tank 1 includes a water inlet pipe 1-1 and an outlet pipe for discharging treated water. The waste water enhanced air flotation tank 1 is sequentially composed of a sand collection area 1-14 and a sludge area 1-1 from bottom to top. 13. Mixing zone 1-12 and separation zone, said separation zone incl...

Abstract

The invention relates to a complex oily wastewater treatment device which comprises a wastewater intensifying flotation tank, an ozonation flotation tank, a modified magnetic seed adsorption coagulative precipitation tank and an activated carbon adsorption tank, wherein the wastewater intensifying flotation tank comprises a sand collecting area, a sludge area, a mixing area, a water collecting area and an oil collecting area; the ozonation flotation tank sequentially comprises a sand collecting tank, a sludge area, a mixing area and a separating area from bottom to top; the modified magnetic seed adsorption coagulative precipitation tank comprises a modified magnetic seed adding and metering system and a coagulant adding and metering system; an activated carbon adsorption layer of the activated carbon adsorption tank is placed in the middle of the tank, and water flows in from the upper part and flows out from the lower part; the wastewater intensifying flotation tank, the ozonation flotation tank, the modified magnetic seed adsorption coagulative precipitation tank and the activated carbon adsorption tank are containers with the upper parts which are cylindrical and the lower parts which are cone-shaped. The containers are vertically arranged. The device provided by the invention is simple in structure, suitable for treating sewage with greater water yield, low in oil content of effluent and high in operating efficiency, and has a biochemical effect and a capability of treating complex oily wastewater.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a treatment method and device for oily waste water. Background technique [0002] Oily wastewater mainly comes from petroleum extraction and processing, chemical industry, metallurgy, machinery industry, textile, food processing industry and marine transportation industry, etc. Oil exists in wastewater in four forms: floating oil, dispersed oil, emulsified oil and dissolved oil, while The composition of oily wastewater produced by the processing of petroleum for various special purposes is more complex. Oily wastewater is extremely harmful. When oily wastewater is discharged into rivers, lakes, seas and other water bodies, it will seriously affect the normal growth of aquatic organisms, make aquatic animals and plants smell oily or toxic, and even die, making the water smelly; destroying water resources Utilization value; oily wastewater contains "three causes" (teratog...
