Technical Field

The utility model relates to a sewage treatment technical field, concretely relates to oil field sewage treatment purifier.

Background

At present, most oil fields in China enter the middle stage and the later stage of oil exploitation, the water content of crude oil reaches 70-80%, and the water content of some oil fields reaches 96% even. If a large amount of oily sewage generated by oil-water separation is directly discharged without being treated to reach the standard, the oily sewage can cause pollution harm to the environment, seriously threatens the life safety of people and causes economic loss. At present, the domestic oily sewage treatment process flow is largely the same and different, and the combination of sedimentation, inclined plate oil removal, air floatation or electric air floatation decontamination and filtration processes is generally adopted.

Sewage treatment is a process of purifying sewage to meet the water quality requirement of draining a certain water body or reusing the sewage.

The bottom of the existing sewage treatment tank is easy to accumulate precipitates which are not cleaned for a long time and are easy to stick to the bottom of the sewage treatment tank, so that the precipitates are very difficult to clean and the treatment of the oil field sewage is relatively complicated.
