Abstract

The invention provides an oily sewage treatment device, and belongs to the sewage treatment field. The oily sewage treatment device can generally include a shell body, an inlet and outlet pipeline, aseparation device and a control unit. The shell body is composed of a cylindrical outer cylinder, an upper seal head and a lower seal head. The inlet and outlet pipeline is composed of an oily sewageinlet pipe, a primary overflow pipe, a secondary overflow pipe and an outlet pipe. The separation device includes a cylindrical inner cylinder, a cylindrical outer cylinder and a swirl guide plate, and the swirl guide plate is fixed on the upper part of the inner wall of the cylindrical outer cylinder. The control unit is connected to a gas-liquid mixer; the gas-liquid mixer is adjusted accordingto the oil content, so as to adjust the gas-liquid volume ratio of the sewage entering the interior of the cylindrical outer cylinder. The sewage treatment device adopts the control unit, and the gas-liquid mixer is adjusted according to the oil content of the oily sewage after treatment, so as to adjust the gas-liquid volume ratio. The oily sewage treatment device has high adaptability to deal with the flow quantity and the fluctuation of the oil content and the gas content and has high operational flexibility.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to an oily sewage treatment device with an automatic adjustment function. Background technique [0002] With the continuous development of oilfields, the water content of oilfield production fluids gradually increases, and the cost of sewage treatment accounts for an increasing proportion of production costs. Due to the needs of environmental protection and the limitation of oilfield permeability, sewage discharge standards and reinjection The requirements are becoming more and more stringent, which put forward higher requirements for the treatment capacity and treatment effect of sewage treatment plants. In addition, for offshore oil fields and some onshore oil fields, due to space limitations, the sewage treatment system needs to be simple and compact. [0003] In order to overcome the shortcomings of traditional air flotation and cyclone and further enhance the oil-water separati...
