Abstract

The invention relates to the technical field of sewage treatment, in particular to an oilfield sewage treatment device. The invention aims to solve the technical problems that the extraction rate of crude oil is easily interfered by using a flocculating agent, large waste is caused, and blockage is easily caused by deposition of part of silt at the bottom of a floating gas tank. In order to solve the technical problems, the oil field sewage treatment device provided by the invention is composed of a settling tank, a stirring mechanism, a floating ball valve mechanism, an oil-water separating tank and an oil-water filtering mechanism, and crude oil floating on the surface of sewage overflows into the oil-water separating tank through a discharge port in the top of the settling tank; and the influence on the extraction rate of the crude oil by using a flocculating agent is avoided, the extraction rate of the crude oil is improved, the waste of the crude oil is greatly reduced, the sewage at the bottom of the settling tank is stirred through the stirring mechanism, so that the sewage at the bottom flows spirally, the settling speed of soil in the sewage is accelerated, and the separating efficiency of the soil and the crude oil and the sewage treatment efficiency are improved.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to an oilfield sewage treatment device and a method for using the same. Background technique [0002] Sewage treatment is the process of purifying sewage to meet the water quality requirements of a certain water body for drainage or reuse. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, catering, etc., and it is also increasingly entering the daily life of ordinary people. [0003] The existing patent (notification number: CN106045125B) discloses a comprehensive oilfield sewage treatment device, which can shorten the treatment time, short hydraulic retention time, small equipment investment, small footprint, and no backwashing. In the process of realizing the present invention, the inventor found that at least the following problems in the prior a...
