Abstract

The invention provides a forced overflow type graphene oil-containing sewage treatment device. A tank is a horizontal cylindrical sealed container, and a nitrogen inlet is arranged at the top of the tank; an oil-containing sewage inlet is connected with an oil-water separation chamber, and a water distribution tube A is arranged in the periphery of the upper part of the oil-water separation chamber; the left side of the oil-water separation chamber is an oil receiving chamber, and the right side of the oil-water separation chamber is a sewage chamber; a water permeation hole is arranged between the oil-water separation chamber and the sewage chamber; the right side of the sewage chamber is a water production chamber, and a water distribution tube B is arranged between the sewage chamber and the water production chamber; a graphene-based screen membrane is distributed below a water spray tube at the upper part of the water production chamber, and an oil receiving tank is arranged at the tail part of the graphene-based screen membrane; an oil receiving tube is arranged at the bottom of the oil receiving tank; and a water tube is arranged at the bottom of the water production chamber. The device has the advantages of high oil removal efficiency, small occupied area, high resistance to pollution, wide inlet water quality requirements, satisfactory adaption to the oilfield sewage conditions, and simple matched treatment process flow.

Description

technical field [0001] The invention relates to the technical field of oil production sewage treatment in oil fields, in particular to a device for removing oil and suspended matter from oil production sewage. Background technique [0002] With the diversification of reservoir development methods, the continuous application of new oil recovery technologies, and the continuous improvement of the recovery rate, the production fluid is becoming more and more complex, the production water is increasing, and the treatment difficulty is increasing. The adaptability of oil removal + two-stage filtration” process needs to be further improved. [0003] At present, gravity degreasing facilities commonly used in oily sewage treatment systems have problems such as low degreasing efficiency and large floor area. Commonly used filtration equipment includes walnut shell filter, emery filter, double filter material filter, multi-media filter, etc., but these filters have high requirements ...
