Abstract

The invention relates to the field of wastewater treatment and resource cyclic utilization, in particular to an electronically-regulated electricity-producing desalting oil field fracturing flowback fluid treatment device and a method for treating oil field fracturing flowback fluid through the device. The device and the method aim at solving the problems that the existing industrial sewage treatment difficulty is large, biochemical treatment is difficult, and energy in the industrial wastewater is wasted. The device comprises an anode chamber, an anode carbon brush, an anion exchange membrane, a desalting chamber, a cation exchange membrane, a cathode carbon brush, a cathode chamber, a reference electrode, an external resistor and an aeration device. The method includes the steps of firstly, domesticating activated sludge; secondly, treating sewage; thirdly, producing electricity; fourthly, desalting treatment. The device and the method are used for treating the industrial sewage.

Description

technical field [0001] The invention relates to the fields of waste water treatment and resource recycling, in particular to an electronically regulated electricity generation desalination device for treating oilfield fracturing flowback fluid and a method for using the device to treat oilfield fracturing flowback fluid. Background technique [0002] Environmental issues and energy issues restrict the development of human society. Due to the continuous development of my country's industry, resulting in a sharp rise in industrial water consumption, which undoubtedly aggravated the crisis of water shortages. A large amount of chemical wastewater produced in the production of chemical industry contains hydrocarbons and other refractory substances. If it cannot be disposed of properly, it will inevitably cause pollution to the receiving environment, threaten the safety of the ecological environment, and endanger the health of humans and other organisms. Therefore, chemical indus...
