Embodiment Construction

[0020] The present invention will be further described in conjunction with the accompanying drawings and specific embodiments, but the present invention is not limited thereto.

[0021] The electrodes used in the following examples: the anode and the cathode are titanium plates; the cationic membrane, the anionic membrane and the proton membrane are all purchased from the market, such as can be purchased from Japan Asahi Glass Company; the material of the reaction device shell is plexiglass.

[0022] see figure 1 , the device is composed of reverse electrodialysis module RED module D, anaerobic ammonium oxidation chamber C and microbial fuel cell module.

[0023] RED module D is composed of alternately arranged anion membranes 11, cation membranes 12 and partitions. The partitions are respectively placed between the alternately arranged anion and cation membranes to form a concentrated water chamber and a fresh water chamber. The working fluid in the chamber is concentrated am...

Abstract

The invention discloses an anaerobic ammonia oxidation microbe reverse electroosmosis sewage treatment and power generation method and device. The device comprises a reverse electroosmosis module, an anaerobic ammonia oxidation chamber and a microbe fuel cell module, wherein the reverse electroosmosis module is a device for generating power by utilizing salinity gradient of an ammonium bicarbonate solution; the anaerobic ammonia oxidation chamber is a device for performing ammonia nitrogen treatment by utilizing anaerobic ammonia oxidation microbes; and the microbe fuel cell module is a device for treating sewage by utilizing power generation microbes and obtaining electric energy. According to the reverse electroosmosis module, the ammonium bicarbonate serves as operating fluid, and ammonium carbonate negative ions pass through the reverse electroosmosis module, enter the anaerobic ammonia oxidation chamber and do not enter an anode chamber of the microbe fuel cell module, so that suppression of ammonia on the activity of the power generation microbes is avoided. The advantages of the reverse electroosmosis module, the anaerobic ammonia oxidation chamber and the microbe fuel cell module can be complemented with each other, the functions are coordinated with one another, and ammonia accumulation is avoided, so that the sewage treatment cost is low, and the power generation capacity is high.

Description

technical field [0001] The invention relates to an electrodialysis sewage treatment technology, in particular to a method and a device for simultaneously generating electricity by anaerobic ammonium oxidation microbial reverse electrodialysis sewage treatment. technical background [0002] With the development of economy, human beings' demand for energy is increasing. The lack of energy and environmental pollution have become one of the most concerned issues in the world, seriously affecting people's daily life. Can the increasing pollutants in today's society be transformed into energy that is constantly lacking? Microbial Fuel Cell (MFC for short) is a device that uses microorganisms to directly convert chemical energy in organic matter into electrical energy. In the anaerobic environment of the anode chamber, organic matter decomposes under the action of microorganisms and releases electrons and protons. Electrons rely on suitable electron transfer mediators to efficien...
