Generally, oil field extracted water salt content high (most of even as high as 290000mg/L between 20000-120000mg/L, having),
Ca2+And SO4 2-Ion concentration is high, often contains a certain amount of HCO in sewage in addition3 -、CO3 2-, therefore sewage fouling belongs to generally existing
As the even strong fouling water having.
Produced water treatment has at present:At Physical, chemical method, physical-chemical process, microorganism treatment etc., wherein microorganism
Reason technology has that the dirty Organic substance in water ability of mild condition, degraded is strong, the feature of stable effluent quality, and therefore, this method turns into
One of method of oil recovery treatment very advantageous.In microbiological treatment technology, obtain dominant degradation bacteria and improve its degraded
Performance is the key of the technology.By effort for many years, activated sludge process, biomembrance process and stabilization pond method etc. have been formd many
Processing method and technique are planted, wherein with activated sludge process using more.
Although biological method processing oil extraction-generated waste water is technically feasible, it is related to microbiological treatment oil extraction-generated waste water and also deposits
In many problems.Such as meeting fouling, sewage fouling meeting because of interionic reaction after the poor multilayer oil extraction-generated waste water mixing of compatibility
Microorganism and extraneous Exchange of material and energy are influenceed, and is suppressed the microorganism in biological treatment system, microorganism is caused
Sewage treatment process treatment effeciency, which declines, even paralyses.
Therefore, need to solve because the high fouling of oil extraction-generated waste water causes dirt in micro- life during microbiological treatment oil extraction-generated waste water
Thing surface deposit and cause micro-organism treatment process bad stability, or even paralysis deficiency the problems such as, in order to avoid influence microorganism
To the efficient degradation of dirty Organic substance in water.
The content of the invention
