Description

Technical Field

[0001] This invention belongs to the field of oilfield wastewater treatment technology, specifically relating to a closed, continuous, high-efficiency treatment device for oily wastewater. Background Technology

[0002] Water injection has become a common practice in oilfield development. Most of the water injected into the oil reservoir comes from the crude oil itself, and currently, wastewater utilization accounts for about 80% of the total injected water. This wastewater contains large amounts of suspended solids, emulsified crude oil, bacteria, and other harmful substances, requiring treatment to meet standards before reinjection. With the advent of tertiary oil recovery, polymer injection, and ternary flooding, oilfield wastewater has become increasingly complex and difficult to treat, especially ternary flooding wastewater. Due to the variety of added chemicals, high emulsification, and small colloidal particles, coupled with the increasing standards for treating and reinjecting or reusing difficult wastewater from polymer injection, ternary flooding, treatment fluids, and drilling fluids, single physical, chemical, or biological methods are currently ineffective, resulting in severely substandard water quality. This has led the petroleum industry to classify it as a global water treatment challenge. Summary of the Invention

[0084] Two booster pumps 5 and their corresponding inlet valves are turned on. Wastewater is pressurized and boosted by the booster pumps 5 before entering the COSSHE high-efficiency processor 6. A first dosing port 22, a second dosing port 23, and a third dosing port 24 are provided on the inlet pipe 25. Simultaneously, pH adjuster, flocculant, and coagulant aid are added through the dosing system.

A third air distribution branch pipe 36 is provided on the inlet pipe 25, which connects to the COSSHE high-efficiency processor tank 84. Air is introduced through the third air distribution branch pipe 36. The wastewater and chemicals are rapidly mixed through the combined mechanical power of the booster pumps 5 and the turbulent flow of the air. The uniformly mixed wastewater enters the high-efficiency processor vortex generator 46 in the COSSHE high-efficiency processor 6 for vortex rotation. The chemical reaction is completed through the combined action of vortex centrifugal force and micro-vortex. After the dual-action flocculation reaction is completed, light oil and gas pass through the COSSHE high-efficiency processor... The high-efficiency processor oil collection pipe 28 at the top of the processor 6 is discharged. The heavy sludge is discharged along the wall of the vortex and through the high-efficiency processor sludge discharge pipe 50 at the bottom of the vortex. The sewage enters the packing layer formed by the high-efficiency processor packing 48 (specifically, the packing is a multi-faceted concentric ball) through the first top funnel outlet 46-1 of the high-efficiency processor vortex 46. Through the mutual collision between sewage and sewage and between sewage and packing, the floc particles are agglomerated and enlarged to form sludge blocks. Solid-liquid separation is completed through the adsorption and gravity settling of the high-efficiency processor packing 48. The separated sewage enters the bottom of the COSSHE high-efficiency processor tank 84 through the through hole on the movable lower baffle 49 of the high-efficiency processor. The flow direction is changed again at the bottom of the COSSHE high-efficiency processor tank 84 and enters the high-efficiency processor settling tank 47.

A second air distribution branch pipe 35 is provided on the inlet pipe 63 of the turbulent air flotation type II processor. Air is introduced through the second air distribution branch pipe 35. After the wastewater and air are mixed, they enter the vortex generator 65 inside the turbulent air flotation type II processor for vortex rotation.

Wastewater enters in reverse through the second top horn-shaped outlet 65-1 at the top of the turbulent air flotation II type processor vortex device 65, and sequentially enters the filter layer formed by the micro vortex packing 56 and the filter media 58 (specifically, walnut shells) of the turbulent air flotation II type processor. Suspended solids and other impurities in the wastewater are adsorbed and trapped by the filter media. The adsorbed and trapped pollutants are discharged during backwashing. The filtered wastewater enters the area where the first electro-cation water processor 61 of groups 4-6 is located. After the electro-cation water processor 61 performs descaling, scale prevention, corrosion inhibition, and sterilization, it is discharged through the turbulent air flotation II type processor outlet and backwash inlet dual-purpose pipe 62 at the bottom of the turbulent air flotation II type processor 7.

[0086] Wastewater filtered by the turbulent air flotation type II processor 7 enters the turbulent air flotation type III processor 8 for fine filtration via the dual-purpose pipe 73 for both the effluent and backwash inlet of the turbulent air flotation type III processor. A first air distribution branch pipe 34 is installed on the dual-purpose pipe 30 for both the effluent and backwash discharge of the turbulent air flotation type III processor. Air is introduced through the first air distribution branch pipe 34, and the wastewater and air mix before entering the turbulent generator 69 inside the turbulent air flotation type III processor to create a vortex rotation. Through the combined action of vortex centrifugal force and micro-vortex, light oil and gas pass through the top of the turbulent air flotation type III processor 8. The wastewater is discharged through the oil collection pipe 31 of the turbulent air flotation type III processor. The wastewater flows downward into the filter layer formed by the packing material 71 (specifically, walnut shells) of the turbulent air flotation type III processor. Suspended solids and other impurities in the wastewater are trapped by the filter material. The adsorbed and trapped pollutants are discharged during backwashing. The filtered wastewater enters the working area of ​​the second electro-cation water processor 87 in groups 4-6. After the electro-cation water processor 87 performs descaling, scale prevention, corrosion inhibition, and sterilization, it is discharged through the turbulent air flotation type III processor outlet and backwash inlet dual-purpose pipe 73 at the bottom of the turbulent air flotation type III processor.

Through multiple instantaneous aerations, the packing layer becomes loose under the rapid disturbance of the airflow, which facilitates the next step of water washing.

[0090] Turn on the backwash pump 11 and the corresponding inlet valve. Clean water flows through the backwash pump 11 and backwash pipe 39 from the liquid outlet and backwash inlet dual-purpose pipe 62 of the turbulent air flotation type II processor and the liquid outlet and backwash inlet dual-purpose pipe 73 of the turbulent air flotation type III processor, and enters the corresponding processor. Maintain a certain pressure (0.05-0.3MPa) and time (10-30min) to allow the water to fill the entire tank. At the same time, open the backwash drain pipe 29 of the turbulent air flotation type II processor and the liquid inlet and backwash drain pipe 30 of the turbulent air flotation type III processor to realize the water flow from bottom to top and backwash the packing layer.

[0091] During the water washing process, the material pump 12 circulation device is turned on at the same time. The discharge pipe 40 is provided in the lower part of the processor tank, and the inlet pipe 38 is provided in the upper part of the processor tank.
