Problems solved by technology

[0006] 1. The grille and regulating pool occupy a large area;
[0007] 2. Large investment in infrastructure and equipment;
[0008] 3. On-site operation requires labor and high operating costs;
[0009] 4. The grille and regulating pool are generally open (not airtight) operation, and the solvent and odor in the sewage volatilize, resulting in environmental pollution

Embodiment Construction

[0026] The specific implementation manner of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0027] Such as figure 1 An oil-containing industrial wastewater treatment device is shown, which includes a frame body 1, an oil-water separation head tank 2 and a floating oil receiving tank 3. The oil-water separation head tank 2 is arranged on the upper part of the frame body 1, and the floating oil receiving tank 3 is arranged The lower part of the frame body 1, the top of the oil-water separation header tank 2 is connected to the oily sewage inlet pipe 4, the oily sewage water inlet pipe 4 extends to the inside of the oil-water separation header tank 2, and the oily sewage outlet 5 is a porous water flow distributor. A water baffle 6 is arranged below the oily sewage water outlet 5 . One side of the oil-water separation head tank 2 is provided with an oil slick overflow port 7 above the oily sewage outlet 5, and the oil sli...

Abstract

The invention relates to the field of environmental protection and particularly relates to an oily industrial wastewater treatment device and a treatment method. The oily industrial wastewater treatment device comprises a frame body, an oil-water separation overhead tank and a floating oil receiving tank. According to the oily industrial wastewater treatment device and the treatment method, the height of an upper-layer floating oil liquid column can be guaranteed, and increasingly-accumulated floating oil can successfully overflow and enter the floating oil receiving tank. Oil-water separationis achieved in a continuous automatic overflowing manner, and the device and the method have the characteristics that capital investment is reduced, the operating cost is reduced, and the operating efficiency of the device is increased.

Description

technical field [0001] The invention relates to the field of environmental protection, in particular to an oily industrial wastewater treatment device and treatment method. Background technique [0002] Industrial sewage from chemical process, before treatment, contains: oils, solvents, mud, etc. floating on the water surface, the chemical oxygen demand (COD value) is high, and it is usually acidic. National environmental protection regulations stipulate that industrial sewage must be discharged up to standard. Industrial sewage treatment usually adopts biological contact oxidation method. Its process flow: grille (intercepting suspended solids and impurities on the water surface, separating oil and water) → lifting pump adjustment → regulating pool (dosing, mixing, adjusting sewage pH value 7-8.5, adding alkali to neutralize acid in water) → contact oxidation Pool (filler, aeration, oxidation) → press filtration of effluent from the secondary settling tank. [0003] Amon...
