Problems solved by technology

But its shortcoming is that the water treated with a large amount of chemicals has become eutrophic, and this eutrophic treated water becomes nutrients for various bacteria and algae in the ground after being reinjected into the formation, which not only makes them reproduce rapidly, but also Produces a large number of metabolites and promotes their mutation
When this water is extracted in the next cycle, it will not only increase the difficulty and cost of demulsification and dehydration of crude oil, but also increase the difficulty of subsequent sewage treatment, which greatly hinders the sustainable development of the oil field.

Abstract

The oil field waste water treating apparatus includes electric antiscaling unit electric flocculating unit, electric air floating unit, fruit husk filter, quartz filter and electric disinfector connected successively with pipeline. In the upper opening part of the electric air floating unit, oil scraper is provided. The oil field waste water treating apparatus has simple operation and is automatic, and the treated water may be re-injected into stratum without damage on ecological environment. The present invention makes it possible to utilize raw oil in the oil bearing waste water, and this changes waste into useful matter while protecting environment.

Description

technical field [0001] The invention relates to the technical field of sewage treatment equipment, in particular to sewage treatment equipment for treating oil field sewage. Background technique [0002] At present, the process of oilfield sewage treatment equipment is generally: dosing → sedimentation → filtration; or dosing → air flotation → filtration. The above-mentioned process has the characteristics of simple operation and strong reliability, and has also achieved good results in practical application. But its shortcoming is that the water treated with a large amount of chemicals has become eutrophic, and this eutrophic treated water becomes nutrients for various bacteria and algae in the ground after being reinjected into the formation, which not only makes them reproduce rapidly, but also Will produce a large number of metabolites, and promote their mutation. When this water is extracted in the next cycle, it will not only increase the difficulty and cost of demul...
