Abstract

The invention provides an oil field oily sewage treatment device based on bio-electronic regulation and control and an electricity generation method by using the oil field oily sewage treatment device and relates to the electricity generation method of sewage treatment, aiming at solving the problems that since an existing oil field oily sewage treatment method cannot reasonably utilize energy sources generated by degrading organic matters, resources are wasted. The oil field oily sewage treatment device based on the bio-electronic regulation and control is characterized by comprising an anode chamber, a cathode chamber, a stirrer, a reference electrode, an anode carbon brush, a cathode carbon brush, an aeration device, an anode chamber water outlet, a cathode chamber water outlet, an ion exchange membrane, an external resistor, a bottom separation net, fillers and a columnar filler barrel. The electricity generation method comprises the following steps: 1, domesticating; 2, carrying out water treatment to generate electricity, wherein the electricity generation is realized by using the oil field oily sewage treatment device based on the bio-electronic regulation and control through adopting an intermittent operation manner. The oil field oily sewage treatment device and the electricity generation method, provided by the invention, are mainly used for treating oil field oily sewage and can also be used for carrying out electricity generation.

Description

technical field [0001] The invention relates to an electricity generation method for sewage treatment. Background technique [0002] my country's oilfields have generally entered the stage of high water-cut production, and a large amount of oily produced water needs to be treated every year. In the previous treatment process, the purpose of oily sewage treatment was to serve oilfield production, so most of the treatment targets set were to meet the water quality standards for reinjection. The water quality indicators concerned were oil content, suspended solids, viscosity, and particle size. The value is the main focus, ignoring the proper disposal and resource utilization of petroleum substances in oily sewage. Therefore, the choice of process is mostly based on traditional gravity sedimentation and filtration. Biological method has become an important direction of research because of its strong adaptability, flexible operation, low treatment cost and no secondary polluti...
