As preferably, the inlet and outlet of the inclined plate sedimentation tank are respectively located on both sides of the inclined plate sedimentation tank, and respectively include an upper inlet and a lower inlet, an upper outlet and a lower outlet; the outlet of the flocculation coagulation tank is communicated with A pipe, and the upper inlet and lower inlet of the inclined plate sedimentation tank are connected to the pipeline through valves; the inlet of the other pump is connected to a pipe body, and the upper outlet and lower outlet of the inclined plate sedimentation tank The outlets are respectively communicated with the pipe body through valves, thereby communicating with the high-pressure gas dissolving tank. After the flocculation and coagulation treatment in the flocculation coagulation tank, considering the specific gravity of the oil residue, different types of oily wastewater alum flowers float up or sink, so the water entering and exiting the inclined plate sedimentation tank enters and exits at the top and exits at the bottom and exits at the bottom. species, which is convenient for on-site specific operations.

The beneficial effect of the utility model is that: the utility model is based on the characteristics of the oily sewage, and the demulsification reaction tank, the flocculation coagulation tank, the inclined plate sedimentation tank, the high-pressure dissolved air tank, the air flotation device and the ultrafiltration device are successively set up in order to gradually clean the water. Oily sewage is subjected to oil-water separation, coagulation and flocculation treatment, solid-liquid separation, pressure dissolved air flotation purification treatment, ultrafiltration treatment, and finally realizes oily sewage treatment better. Compared with the prior art, the utility model has low cost, It has the advantages of fast treatment speed, good treatment effect and convenient use. It is a mobile oily sewage treatment device that can be used in different places.

detailed description

The utility model will be further described below in conjunction with the accompanying drawings. It should be noted that the present embodiment is based on the technical solution and provides detailed implementation and specific operation process, but the protection scope of the utility model does not limited to this example.

As shown in Figure 1, a rapid treatment device for oily sewage includes a demulsification reaction tank 1 for adding a demulsifier, its inlet is connected to the oily sewage pipe 3 through a pump 2, and its outlet is connected to the inlet of the flocculation coagulation tank 4 , the flocculation coagulation tank 4 is used to add coagulant and flocculant; the outlet of the flocculation coagulation tank 4 is connected to the inlet of the inclined plate sedimentation tank 5, and the outlet of the inclined plate sedimentation tank 5 passes through another The pump 6 is communicated with the inlet of the high-pressure dissolving tank 7; the outlet of the high-pressure dissolving tank 7 is communicated with the inlet of the air flotation device 8, and the outlet of the air flotation device 8 is communicated with the inlet of the ultrafiltration device 9; The outlet of the ultrafiltration device 9 is connected to the outlet pipe 10.

Preferably, the demulsification reaction tank 1 and the flocculation coagulation tank 4 are respectively equipped with a mixer 11 , and the head of the mixer 11 is located in the corresponding demulsification reaction tank 1 or flocculation coagulation tank 4 . Stirring can make the reaction in the demulsification reaction tank and the flocculation coagulation tank more sufficient and effective.

As preferably, the inlet and the outlet of the inclined plate sedimentation tank 5 are respectively located on both sides of the inclined plate sedimentation tank 5, and respectively include an upper inlet and a lower inlet, an upper outlet and a lower outlet; the flocculation coagulation tank 4 The outlet is communicated with a pipeline 12, and the upper inlet and the lower inlet of the inclined plate sedimentation tank 5 are respectively communicated with the pipeline 12 through a valve 13; the inlet of the other pump 6 is communicated with a pipe body 14, and the The upper outlet and the lower outlet of the inclined plate sedimentation tank 5 are communicated with the pipe body 14 through the valve 13 respectively, thereby communicated with the high-pressure gas dissolving tank 7 .

When in use, the oily sewage first enters the demulsification reaction tank from the oily sewage pipe through the pump, and achieves the purpose of oil-water separation through the action of the demulsifier in the demulsification reaction tank under the required pH conditions, changing the traditional strong acid or conventional chemical demulsification. Milk, making the operation safer and easier, and the treatment effect is better. During the demulsification process, the mixer will stir the mixture in the demulsification reaction tank to make the reaction more complete. The reactants in the demulsification reaction tank flow to the flocculation and coagulation tank by themselves, and under the action of the mixer, the oil droplets are condensed to form large alum flowers; the waste water from the flocculation and coagulation tank flows to the inclined plate sedimentation tank for solid-liquid separation. The specific gravity of the oil residue, different types of oily wastewater alum floats or sinks, so the water entering and exiting the inclined plate sedimentation tank is up and down and down and up, which is convenient for specific operations on site. The water from the inclined plate sedimentation tank is pumped to the high-pressure dissolved air tank and pressurized to a certain extent. At the same time, compressed air is added to the high-pressure dissolved air tank, and the air dissolves in the pressurized water; the pressurized dissolved air When the water enters the air flotation device, the dissolved air water is suddenly reduced to normal pressure, and the air dissolved in the water is precipitated from the water in the form of tiny bubbles, and the suspended particles in the water are floated on the water surface, and the slag scraper in the air flotation device Scraped out to achieve solid-liquid separation. After being treated by the air flotation device, the water body is further improved, and the effluent of the air flotation device is further treated by the ultrafiltration device and then discharged or reused up to the standard.

For those skilled in the art, various corresponding changes and modifications can be made according to the above technical solutions and ideas, and all these changes and modifications should be included in the protection scope of the claims of the present utility model.
