Problems solved by technology

Its advantage is that it can completely oxidize organic matter to produce carbon dioxide and hydrogen. The disadvantage is that the purity of its reaction substrate is relatively high, and MFC makes up for this problem.

Embodiment

[0022] as attached figure 1 As shown, a method for producing hydrogen from organic waste is characterized in that it comprises the following steps:

[0023] First, the organic matter is pretreated;

[0024] Next, the organic waste pretreated in the first step is mixed with the inoculum containing hydrogen-producing bacteria and placed in an anaerobic fermentation reactor for anaerobic fermentation. The pH is controlled between 4 and 7.5 to produce hydrogen, carbon dioxide and organic waste. Acids and gases are separated and removed to obtain relatively pure hydrogen, and the remaining liquid containing organic acids is discharged from the anaerobic fermentation tank.

[0025] Then, part of the organic waste pretreated in the first step and part of the organic acid waste liquid generated in the second step enter the anode chamber of the microbial fuel cell, and are oxidized by electrogenic bacteria to produce carbon dioxide, protons and electrons, and the electrons pass throug...

Abstract

A method for preparing hydrogen by using organic wastes comprises the following steps: 1, preprocessing organic matters; 2, mixing the preprocessed organic wastes obtained in step 1 with a hydrogenogen-containing inoculum, placing the above obtained mixture in an anaerobic fermentation reactor, and carrying out anaerobic fermentation; and 3, introducing parts of the preprocessed organic wastes obtained in the step 1 and parts of an organic acid waste liquid generated in the step 1 to an anode chamber of a microbiological fuel cell in order to produce an electrogenesis effect, introducing parts of an organic acid waste liquid obtained in step 2 to an anode chamber of a microbial electrolysis cell, and generating hydrogen by protons permeating an exchange membrane and electrons on a cathode under the catalysis under a voltage applied by the microbiological fuel cell in order to realize microbial electrolysis hydrogen production. The method and the apparatus have the advantages of energy consumption reduction, full recycling and pollution reduction in the biological hydrogen production process of the organic wastes by utilizing an MFC-MEC self-power system to provide energy needed by hydrogen production.

Description

technical field [0001] The invention belongs to the field of comprehensive treatment of organic waste and development of clean energy, and specifically relates to a method and device for biological hydrogen production using organic waste through a self-powered system Background technique [0002] The excessive development and utilization of fossil fuels has brought about a series of environmental problems such as air pollution and global warming, and the increasingly depleted fossil fuel resources are also difficult to meet people's rapidly growing energy needs. Based on the requirements of the environment and energy, people urgently need to develop clean and renewable energy as the main energy source. Hydrogen energy is an ideal clean energy with high calorific value, which can generate water after full combustion without producing greenhouse gases and pollutants. Considering environmental issues, biohydrogen production from organic waste has become a major research hotspo...
