Problems solved by technology

[0002] With the extensive use of polymer flooding technology in oil extraction, although the oil recovery rate has been stabilized, it has greatly increased the difficulty of producing water treatment, because the sewage containing polymer has high viscosity, high emulsification degree, and difficult oil-water separation. characteristics, and due to the problem of large suspended solids due to high viscosity, etc., the processing cost is virtually increased, so how to reduce the cost under the condition of meeting the processing standard becomes a key issue

Abstract

The invention provides a device and method for producing electricity by utilizing a polyacrylamide solution specially used for an oil field and relates to a device and method for producing electricity. The device provided by the invention is composed of a cathode chamber, an anode chamber, a proton exchange membrane, a titanium wire brush, a reference electrode, an external resistor, two water outlets, two feeding holes, a conducting wire, a cavity and an aerator. The method provided by the invention comprises the following steps: adding a polyacrylamide solution into two reaction chambers, respectively adding a certain amount of domesticated activated sludge into the reaction chambers as starting microorganisms, and starting and running at room temperature, so that electric current can be produced. Microbial florae used in the method provided by the invention are from activated sludge which is domesticated with the polyacrylamide solution for a long time, reaction is started by virtue of the method, and the advantages of quick electricity production and maintenance of the whole relatively stable system are achieved; meanwhile, the method is carried out at normal temperature and heating does not need to be carried out, so that energy is saved, the device and the method which are provided by the invention have a broad application prospect, and important theoretical reference and practice are provided for recycling and energy utilization of oilfield sewage.

Description

Technical field [0001] The present invention relates to the field of resource utilization and energy recovery of petroleum production wastewater. A method and device for generating electricity using polyacrylamide commonly used in chemically driven oil production are developed, and a method and device for recycling polymer-containing wastewater is developed. New technologies to harm. Background technique [0002] With the extensive use of polymer flooding technology in petroleum exploitation, although the oil recovery rate has been stabilized, it has greatly increased the difficulty of produced water treatment. Because sewage containing polymers has high viscosity, high emulsification, and oil-water separation is difficult In addition, due to the high viscosity resulting in larger suspended solids and other problems, the processing cost is virtually increased, so how to reduce the cost while meeting the processing standards has become a key issue. [0003] At present, when the exi...
