Problems solved by technology

Conditioning-mechanical dehydration can effectively separate oil-water-sludge, but the resulting mud cake needs further treatment; biological treatment can completely degrade organic matter in oily sludge into CO2 and H2O, but the degradation efficiency needs to be improved; solidification can greatly reduce the seepage rate of harmful substances; resource utilization will become the development trend of oily sludge treatment technology

Embodiment Construction

[0023] A mobile oilfield oily sludge biological, conditioning and tempering separation treatment device, the device is divided into pretreatment and screening process section ①, primary oil sludge treatment process section ②, secondary oil, water, mud separation process section ③, biological sludge Treatment process section ④, oil-water separation treatment process section ⑤, mud sand treatment process section ⑥;

[0024] The pretreatment screening process section ① consists of feed screening machine 1, three-stage oil-water screening pool 2, and 2mm vibrating screen 3; the main function of the pretreatment screening process section is to remove large-size sludge particles and change the sludge flow state. The raw material enters the feed screening machine 1, and the sludge enters the hopper through the hopper grille to remove solid particles larger than 20 mm, and removes large-volume stones, waste materials, and woven sundries for external transportation. The screened materi...

Abstract

Provided is a movable oil field oily sludge biological tempering separation treatment device. The device comprises a pretreatment screening process section, a primary oil-mud treatment process section, a secondary oil-water-mud separation process section, a biological sludge treatment process section, an oil-water separation process section, a sand treatment process section and other sludge treatment systems. Each process section of the device is independently prized and modularized, transportation is convenient through prizing, and aiming at the characteristics that remote oil fields, factories and mines and other blocks are scattered and are poor in ground environment condition, the movable oily sludge treatment device has the design rule of being simple, applicable, safe and reliable and meeting production. The device achieves equipment concentration and overall prizing, can be transported to all oil-mud dispersion points, and meanwhile can achieve the treatment effect of a fixed sludge treatment station, and convenience is brought to enterprises with small oil-mud output and remote locations.

Description

[0001] Technical field: [0002] The invention is a device for advanced treatment of oily sludge in oilfields. It relates to a mobile oilfield oily sludge biological, conditioning and tempering separation treatment device. [0003] Background technique: [0004] With the deepening of oilfield development, a large amount of oily sewage and oily sludge will be produced in the process of oilfield development and production. Oilfield oily sludge mainly includes landing sludge, settling tank sludge, sediment at the bottom of sewage treatment plant structures, three-phase separator sludge, and oil spill sludge from production accidents. With the increase of oil exploration, development and production activities, the total amount of oily sewage and oily sludge produced is increasing, and the pollution to the environment is becoming more and more serious. Tertiary oil recovery technology has become one of the main measures to improve oil recovery. However, it increases the difficulty...
