Abstract

The invention relates to the technical field of foam drainage wastewater treatment, and discloses an electrocatalytic oxidation treatment method for foam drainage gas production wastewater, which comprises the following steps: s1, collecting the foam drainage gas production wastewater into a collecting tank, and then carrying out precipitation treatment; s2, a homogeneous receiving tank: introducing the settled sewage into the homogeneous receiving tank, recovering free oil obtained at the upper part through gravity separation, storing the free oil in a dirty oil recovery tank, and collecting other bubble drainage water; s3, coagulating sedimentation: introducing the treated foam drainage water into a coagulation device for coagulation treatment; and s4, treatment with an electrolytic oxidation pond. According to the method, high-salt-tolerance microorganisms are adopted to carry out biochemical treatment on the soaking drainage water. The treatment process is simple, the energy consumption is low, and various substances in the bubble drainage water can be thoroughly treated. In addition, through cooperative use of a poke rod and a spiral sheet, stirring and mixing of mixed wastewater are realized, and the mixing effect of the device is improved.

Description

technical field [0001] The invention relates to the technical field of bubble drainage wastewater treatment, in particular to an electrocatalytic oxidation treatment method of bubble drainage gas production wastewater. Background technique [0002] With the continuous development of gas fields and the improvement of reserves production, the water production of gas reservoirs and the number of water production wells are increasing, and problems such as fluid accumulation in wellbore and water production of gas wells affecting normal production have gradually emerged. Fluid accumulation in the wellbore will increase the back pressure on the gas layer and limit the production capacity of the well. If the fluid accumulation in the wellbore is too large, the gas well will stop blowing completely. In addition, the liquid column in the wellbore will damage the formation near the wellbore, reduce the gas phase permeability, and seriously affect the ultimate recovery of the gas field...
