Three-chamber electrodialysis hydrogen production fermentation reactor and hydrogen production method

Abstract

The invention discloses a three-chamber electrodialysis hydrogen production fermentation reactor and a hydrogen production method. The three-chamber electrodialysis hydrogen production fermentation reactor includes: an anode chamber, a fermentation chamber, a cathode chamber, a cathode electrode, an anode electrode, an anion exchange membrane and a cation exchange membrane. The fermentation reactor is characterized in that: the cathode chamber and the fermentation chamber are separated by the cation exchange membrane; the anode chamber and the fermentation chamber are separated by the anion exchange membrane; the cathode electrode and the anode electrode are respectively disposed in the cathode chamber and anode chamber; and the cathode electrode and the anode electrode are inert graphiteelectrodes, the electrode surface area is the same as the ion exchange membrane surface area, the cathode electrode and the anode electrode are externally connected to a direct current power supply negative pole and positive pole respectively, the upper part of the cathode chamber is equipped with a first discharge and drain port, and the lower part is equipped with a first water inlet. The reactor provided by the invention can achieve effective removal and enrichment of ammonia nitrogen in high ammonia nitrogen organic wastewater and volatile fatty acids produced during fermentation, and canbe widely applied to biology, energy, chemical industry and other fields.

Description

technical field [0001] The invention relates to a fermentation reactor, in particular to a three-chamber electrodialysis hydrogen production fermentation reactor and a hydrogen production method. Background technique [0002] The direct discharge of organic wastewater from agriculture and animal husbandry will cause serious environmental pollution due to the high content of COD and ammonia nitrogen, so it needs to be treated before discharge. The use of anaerobic fermentation hydrogen production technology to treat agricultural and animal husbandry organic wastewater can not only bring environmental benefits, but also bring added value because anaerobic fermentation hydrogen production technology can use microorganisms to digest organic matter to generate hydrogen. As a clean energy, hydrogen energy is known as the most potential energy in the 21st century. In the process of anaerobic fermentation hydrogen production, microorganisms can digest organic matter in wastewater t...
