Problems solved by technology

At present, seawater desalination has spread to 125 countries and regions all over the world, and desalinated water feeds about 5% of the world's population. Among them, distillation, electrodialysis, ultrafiltration-reverse osmosis, etc. are currently the main desalination processes, and these processes have high treatment efficiency. But it comes with high power consumption

Abstract

The invention belongs to the technical field of water resource processing, and in particular relates to a technology and a device for processing sewage from synchronous electricity generation and desalting, which comprises an anode chamber, an anion exchange membrane, a middle desalting chamber, a cation exchange membrane and a cathode chamber. An electric generation microorganism membrane is arranged on an anode. Sewage flows into the anode chamber and is removed by oxidization under the action of electric generation microorganisms, and electrons are conducted to the anode. Anions in the middle desalting chamber penetrate the anion exchange membrane to reach the anode, and cations penetrate the cation exchange membrane to reach the cathode to realize the desalting processing and form internal currents. The electrons reach the cathode by external circuit loading to generate reduction reaction to realize the electricity generation process. The internal currents of the microorganism fuel battery are used for sewage processing, electric generation and desalting. The technology of the invention is simple and easy to operate and has low energy consumption and high efficiency. The device is simple in structure and is convenient for industrial production and utilization.

Description

technical field [0001] The invention belongs to the technical field of water resources treatment, and in particular relates to a sewage treatment process and device for synchronous electricity generation and desalination. Background technique [0002] Water is an important natural resource for human survival. The deterioration of the global water environment and the severe energy crisis urgently require high-efficiency and low-consumption sewage resource technology to alleviate the shortage of water resources and the demand for energy. 97% of the total water reserves on the earth are salt water (including sea water and brackish water). To obtain fresh water from the sea and salt lakes to alleviate the increasingly serious world water crisis has not only formed a consensus in the global scientific and technological circles, but also has become a The governments of the coastal countries propose and develop new water sources. At present, seawater desalination has spread to 12...
